Polyvinyl chloride kitchen and bathroom board and preparation method thereof

Abstract

The invention discloses a polyvinyl chloride kitchen and bathroom board and a preparation method thereof, belonging to the technical field of polyvinyl chloride plates. The invention solves the problems that hydroscopicity of an existing product is poor, density is low and hardness is poor. The polyvinyl chloride kitchen and bathroom board is prepared from 60-80 parts of polyvinyl chloride SG8 resin, 40-60 parts of ground calcium carbonate, 20-40 parts of reclaimed materials, 7-9 parts of a foaming regulator, 2.7-2.9 parts of a lead salt stabilizer, 0.5-0.6 part of an internal lubricant SP-60,0.2-0.3 part of polyethylene wax, 0.2-0.25 part of micronized polyethylene wax N-14P, 0.1-0.15 part of a plasticizer OA6, 0.5-0.6 part of a heat release type AC foaming agent, 1.2-1.4 parts of a heatabsorption type foaming agent and pigments. The preparation method thereof comprises the following steps: sequentially putting materials into a hot mixing pot, heating and then cooling, and then conveying the cooled materials to an extruding machine, so that the finished product is obtained. The invention is mainly applied to preparation of the polyvinyl chloride kitchen and bathroom board.

Description

technical field [0001] The invention relates to a polyvinyl chloride kitchen and bathroom board and a preparation method thereof, 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 board...

AI Technical Summary

Problems solved by technology

[0003] For PVC kitchen and bathroom boards, the difficulty in production is that the density cannot be improved, the board is brittle and easy to break, the surface hardness is low, the water absorption rate is too high, the nail holding force is low, and the production cost is high. The production is unstable.

The production formula and process setting are also constantly changed and debugged with the production, and large-scale stable and unified production cannot be achieved, and the existing formula composition is relatively complicated
