Description

Microporous foam light-weight decorative slabstone and preparation technology

Technical field

The present invention relates to building material field, and in particular to decoration uses microporous foam light-weight decorative slabstone and preparation technology.

Background technology

With the rapid development that science and technology is with rapid changepl. never-ending changes and improvements, the update of housing construction material constantly accelerates, various The continuous release of new material, style and quality.So that the outward appearance of building is more beautiful, environmental protection, urban architecture is changed The machine-made outward appearance of thing.The innovation of architectural construction technology, the continuous release of New Building Materials, with advances in technology, builds The design that thing respectively has personalization is built, constructing operation is simple and efficient, and construction cost is more cheap, will be mesh that people constantly pursue Mark.At present, more most than the skin of higher gears using patch stone slab, this is the construction technology that a comparison is difficult to carry out. Because stone slab itself is heavier, only by one layer of cement mortar being put on metope, bulky stone slab is adhered on wall much Cannot.Because its own is heavier, it can not be made to be joined together with wall, and need to bear extremely hot severe cold, exposed to the sun and rain Long-term harsh environmental test, stone slab have the danger to come off at any time.In order that stone slab is combined together with wall, people Employ stone plate dry hanging.Stone plate dry hanging construction is complicated；First have to drill out many expansions on the metope for wipe cement mortar Screw hole, then stone slab is fixed into angle bar with setscrew and is installed on wall.Fixing groove is also opened at the back side of stone slab, then is adopted Stone slab is fixed to screw and installed on the angle bar corrected.Then cement mortar is spread at the back side of stone slab to fix. The construction technology is very complicated, and required precision is high, and difficulty of construction is big, and speed of application is slow, and building cost is very high.

The content of the invention

Present invention aims at microporous foam light-weight decorative slabstone is provided, the plate light-weight foam, cohesive is good, form of construction work It is simple and direct.

Microporous foam light-weight decorative slabstone, from top to bottom include stone panel successively and be bonded in stone panel inner face Bottom plate, the bottom plate are sufficiently mixed in proportion by perlite, stone flour, clinker, cement, string, solid blowing agent, water Stirring perfusion forms, and described each substance weight part is：Perlite is 15-25%, stone flour 4-8%, clinker 5-10%, cement For 25-35%, string 3-8%, water 25-35%, solid blowing agent 2-5%, through crushing, fineness is the stone flour 80-120 mesh, for the clinker through crushing, fineness is 80-120 mesh, and the string is monofilament length 3-7mm, the cement For portland cement;The thickness ratio of stone slab and bottom plate is 1：2.5-3.2；The thickness of the stone slab is 5-7 millimeters, bottom plate Thickness be 12.5-22.5 millimeters.

Another object of the present invention is the preparation technology for providing microporous foam light-weight decorative slabstone：1, surface treatment：Naturally The cutting of stone slab, grinding；The surface of natural stone is ground, the adhesive surface of natural stone is carried out at roughening Reason;2：Crush, mixing；Stone flour and clinker are crushed, then weigh each material in proportion, pearl is first added into mixer Rock, stone flour, clinker, cement, string, solid blowing agent carry out being sufficiently mixed stirring, add the water weighed in proportion and stir Mix 3 minutes, the agitator axle of the agitator is hollow structure, and it is empty to add the constant compression of pressure into material while stirring Gas, gas are entered in material by hollow agitator axle, and minute bubbles are formed in material, on mixing oar material surface after stirring When there is bubble, stop stirring and be irrigated at once;The air pressure is 0.5-0.8mpa, 3：Perfusion, foaming：Will be natural Stone slab is placed in the bottom of mould, and bonding is face-up, and the inorganic material being sufficiently mixed after stirring is controlled by PLC single-chip microcomputers, Quantitative perfusion is on natural stone, and after shaking levelling, stand foaming is after 20-30 minutes, the demoulding, then after standing 10 hours Accurately cut flat with by specification；4th, examine;5, packaging.

In order to increase the resistance to compression of micro cellular foam, tensile strength effect, the mixing oar material can also add polymer addition Agent, the polymeric additive are polyvinyl alcohol, and the weight ratio for mixing oar material and polyvinyl alcohol is 100：7-8, the solid hair Infusion is aluminium powder, and for the rotating speed of the agitator between 700~1000r/min, the peripheral speed of impeller end is 20-40m/ S, the string are monofilament, and length is 3-7 centimetres.

Due to using said structure and technique, good, the relatively low water absorption rate of the plate fire protecting performance, practical thermal conductivity factor are reachable 0.07[W/(m•k）, form of construction work it is simple and direct, and high-strength light, mitigate building loading, sound insulation value, compressive property, shock resistance It can work well, can also increase the effect of its toughness.
