Description
Technical field
The present invention relates to a kind of hot water bag, be specifically related to the preparation method of a kind of silica gel heat water bag, belong to heating system skill
Art field.
Background technology
The hot water bag of commercial type is all natural rubber hot water bag at present.The main material of natural rubber hot water bag is sky
So rubber, main manufacturing process is usually refined glue (adding the auxiliary agent such as vulcanizing agent, accelerator mixing), is hacked, vulcanizes, solder tail, repaiies
The operations such as limit.The feature of natural gum hot water bag is as follows:
First, manufacturing process is complicated, uses table of equipment set many, and power consumption is big.
Second, product is the most aging, and service life is shorter.
3rd, low temperature resistant resistance to elevated temperatures is compared with rubber polymer, relatively poor.
4th, in use there is the taste of one plastics, serviceability is poor.
Publication number 102173065A, publication date in JIUYUE, 2011 Chinese invention patent of 7 days disclose a kind of cloth and mould hot water
The processing method of bag, comprises the following steps:
First, first take internal layer, heat-insulation layer and cladding material；
Second, internal layer, heat-insulation layer and outer layer are stacked gradually as combination layer；
3rd, use the mould array being set up in parallel on high-frequency thermocompressor that combination layer is entered two-layer combination layer correspondence overlap
Row high frequency heat bonds, and obtains at least two connected hot water bag bags；
4th, utilize the cutting mould array corresponding with mould that hot water bag bag is carried out die cut, obtain single
Hot water bag Bag structure；
5th, internal layer and outer layer to single hot water bag bag mouth surrounding use high frequency heat seal to carry out sealing heat bonding；
6th, take polypropylene material and obtained the screw thread obturating plug of axially disposed through hole by injection mo(u)lding, then screw thread obturating plug is made
Put into mould for insert, take pvc material and be wrapped in the screw thread on screw thread obturating plug in the outer quadric injection mould formation of screw thread obturating plug
Obturating plug overcoat, the outer wall of screw thread obturating plug overcoat is symmetrically formed two polrvinyl chloride projections；
7th, the screw thread obturating plug being threaded obturating plug overcoat is loaded bag mouth, the symmetrical projection on screw thread obturating plug overcoat is the most right
The heat bonding limit of quasi-hot water bag opening, uses high-frequency thermocompressor to carry out hot sticky to hot water bag bag mouth internal layer and screw thread obturating plug overcoat
Close；
8th, take the screw thread gag that plastic material injection preparation matches with screw thread obturating plug；
9th, go silastic material to prepare gasket seal；
Tenth, the assembling of screw thread gag, pad and screw thread obturating plug is i.e. completed the preparation of cloth-plastic hot-water bag.
Use said method, need to first pass through high-frequency thermocompressor and carry out high frequency heat bonding, the most also need punching press to cut out, afterwards
Also need to internal layer and outer layer are carried out high frequency heat and, complicated process of preparation, processing and manufacturing difficulty, production cost is high.
Accordingly, it would be desirable to a kind of new hot water bag.
