Description
What the present invention relates to is that the passenger train floor (refers to lavatory, sanitary accomodation and kitchen floor, manufacture method down together) and the product of making by this method, especially utilize special material formulation, through methods such as stirring, casting, vibration, curing moldings, and the product of making by this method.
In China, passenger train is the national main vehicle, and people Duo Che is few, facility frequency of utilization height on the car very easily damages, particularly the train sanitary accomodation, more need the intensity height, antivibration, abrasion resistant material, and China railways bus deck, what the first generation was used is cement concrete material, is hard brittle material, and intensity is low, damage easily, repair difficulty, the water absorption rate height, easy to leak, rough surface easily adsorbs dirt, clean very difficult, globality is poor, and not attractive in appearance, concrete floor is cast onboard, curing time is long, prolonged the production cycle of train, train floor glass-felt plastic that the second generation adopts (FRP) material, this material hygroscopic character height, rigidity is poor, easily subside, poor fire, and also the Ministry of Railways has banned use of glass-reinforced plastic material to do floor, train sanitary accomodation.
Purpose of the present invention overcomes above-mentioned shortcoming exactly, adopt special material formulation and technology, thereby make a kind of intensity height, resistance to abrasion height, the passenger train floor that shock resistance and compressive strength are high, utilize technology of the present invention, make its product texture good, the surface finish height, do not adsorb dirt, easy cleaning, bright and clean lucid and lively, improve and beautified environment of toilet.
Passenger train method for making floor of the present invention; it is characterized in that: sprayed surface gel coat and place built-in fitting on floor mold; the surface gel coat is made of bisphenol A-type and Buddha's warrior attendant powder; behind surperficial gel coat semi-solid preparation; with the surface mix expect into and vibration; wherein should comprise that high fineness natural stone-powder and low contraction corrosion resistant unsaturated polyester and EM hindered the agent of contracting by the surface mixture; natural stone-powder is a calcium carbonate; silica flour and aluminium hydroxide; resin is adjacent benzene type agate resin; their weight mixture ratio is 1: 3.5(stone flour: resin); this skin depth is 6mm; surplus glue bond one deck enhancement Layer according to vibration; this enhancement Layer is a glass fabric; chopped mat etc.; thickness is 1.5mm; can smear one deck resin glue as required; the agent structure mixture that stirs; and then casting and vibration; this agent structure mixture is varigrained natural stone-powder and low unsaturated water-fast resin and the initiating agent of shrinking; for alleviating product weight; can add some micro glass beads; wherein natural stone-powder is a calcium carbonate; quarz sand and aluminium hydroxide; resin is the water-fast resin of adjacent benzene type; natural stone-powder need carry out pretreatment; promptly heat more than 85 ℃ and add coupling agent; stir in a container high speed; so that natural stone-powder is easy and resin bond; the weight ratio of natural stone-powder and resin is 1: 5; after its agent structure is solidified; lay down product template on every side; daub clothing again around the mould of not laying down that is contacted with the surface; hinder right resin and adhesive surface felt and glass fibre; form a solid plate; behind the semi-solid preparation; paste protective cover then in its product periphery and around the coaming plate; this protective cover comprises flame-retarded resin and glass fibre; and pasting 4 layers at least, the whole demoulding behind the semi-solid preparation makes its product behind ultraviolet hot setting.
In surperficial mixture, also can add weight and be 3% chopped fiber, and the fineness of used high fineness natural stone-powder is 300～350 orders, for making its surface aesthetic in its mixture, add mill base, the surface gel coat also can add mill base, wherein also can to add weight be 12～15% Buddha's warrior attendant powder to gel coat, and the described EM resistance agent use amount that contracts accounts for 7% of weight resin.In its agent structure mixture, be the micro glass bead that 40～350 orders do not wait for loss of weight adds granularity, it accounts for 3～5% of its total weight, the granularity of stone flour is 350 orders～1 millimeter in the agent structure mixture, also can add some short felt and chopped fiber and antiseptic fire-retardation resins in this agent structure mixture.For making its product expendable weight, can adopt part hollow (solid part adds micro glass bead) structure.
The product of making by said method comprises built-in fitting, the surface gel coat, superficial layer, enhancement Layer, between its surperficial gel coat and superficial layer, be provided with some drainage grooves, the agent structure layer is arranged below enhancement Layer, in the agent structure layer, be expendable weight, adopt some hollow structures, at the outside matcoveredn of its product and also comprise a coaming plate, in this product, surperficial gel coat is bisphenol A-type and has weight to account for 12～15% Buddha's warrior attendant powder; Described superficial layer comprises that natural stone-powder and low contraction corrosion resistant unsaturated polyester and EM hinder the agent of contracting, and this surface thickness is 6mm, and wherein natural stone-powder is calcium carbonate, silica flour and aluminium hydroxide, the weight ratio of natural stone-powder and resin 1: 3.5; It is 3% chopped fiber that weight also can be arranged, and the fineness of natural stone-powder is 300～350 orders, and the described EM resistance agent of contracting accounts for 7% of weight resin, also can comprise mill base, and this layer thickness is 6mm; Described enhancement Layer is glass fabric and resin glue, and thickness is 1.5mm; Described agent structure layer adds that by the natural stone-powder and the water-fast resin of adjacent benzene type of 350 orders～1 millimeter different fineness initiating agent is constituted, stone flour comprises calcium carbonate, silica flour, aluminium hydroxide, the proportion of stone flour and resin is 1: 5, for alleviating product weight, it is 40～350 purpose micro glass beads that 3～5% granularity of total weight can be arranged; In this agent structure, also reinforcing material can be arranged, promptly adopt the glass fabric of different size, felt and chopped fiber and antiseptic fire-retardation resin.Described protective cover mainly comprises flame-retarded resin (3911) and initiating agent and glass fibre; after making this product place the sanitary accomodation, be convenient to settle, a coaming plate (label as shown in FIG.) can be set; this coaming plate is mainly by surperficial gel coat, and surperficial felt, glass fibre and flame-retarded resin are formed.
