Abstract

The invention provides a preparation method of a polyvinyl chloride kitchen / bath board. The preparation method of the polyvinyl chloride kitchen / bath board comprises the following steps of sequentially feeding materials, i.e. a reclaimed material, a plasticizer, polyvinyl chloride resin, triple superphosphate, a modifier, polyvinyl chloride resin, triple superphosphate and a reclaimed material into a heat mixing pot, stirring and heating for 30 to 40min until the temperature is 100 DEG C, then adding the residual materials, stirring and heating for 10 to 12min until the temperature is 120 DEGC, then cooling for 3 to 5min until the temperature is 60 to 70 DEG C, cooling for 10 to 20min until the temperature is 40 to 50 DEG C, then conveying a cooled material to an extruder, heating througha charging barrel screw rod so as to plastify favorably, conveying to a mold, controlling the temperature and the pressure in the mold, extruding, cooling, laminating and shaping through a shaping table, and dragging through a dragger so as to obtain a finished product. The polyvinyl chloride kitchen / bath board has the advantages of low density, high hardness, high nail-holding ability and low water absorption rate.

Description

technical field

[0001] The invention relates to a preparation method of a polyvinyl chloride kitchen and bathroom board, belonging to the technical field of polyvinyl chloride boards. Background technique

[0002] In recent years, with the development of the economy, the government has paid more and more attention to the environment. The country vigorously advocates the development of energy-saving and green products, and PVC is an energy-saving and environmentally friendly product. Therefore, the promotion and application of PVC products is an important measure to save resources, save energy, "replace wood with plastic" and "replace steel with plastic". Among them, PVC board has the characteristics of being sawn, nailed, planed, and glued, and has the characteristics of waterproof, fireproof, insect-proof, alkali-resistant, anti-corrosion, sound insulation, good stability and weather resistance. It has a very good development and is widely used in furniture boards, constr...
