Problems solved by technology

[0004] In the literature disclosed above, the waste material accounts for a small percentage of the entire raw material, resulting in a high cost of the material, and in the manufacturing process, the raw material needs to be mixed at high temperature and then rapidly cooled to be extruded, and during the heating and cooling process, both It needs to consume a lot of energy, which makes the production cost high and the forming efficiency of the plate is low

Abstract

The invention discloses a PVC (polyvinyl chloride) board and a production method thereof. The PVC board is produced from 84-86% of PVC scrap, 7-8% of calcium powder, 0.8-1.1% of a stabilizer, 3.5-4% of a foam control agent, 0.15-0.3% of a yellow foamer, 0.4-0.7% of a white foamer, 0.05-0.25% of PE (polyethylene) wax, 0.2-0.4% of OK60, 0.15-0.3% of OA6 and 1-1.7% of ACM. The production method comprises the following steps: performing low-temperature mixing, extruding, cooling and shaping. The PVC board produced by the production method is high in hardness, good in fire-proof performance and good in high temperature resistance; the production method is energy-saving, low in cost and high in efficiency.

Description

technical field [0001] The invention relates to a PVC board and a production method thereof. Background technique [0002] In the construction industry, the traditional formwork is basically wood formwork, but wood formwork is a loss of natural resources, and it is easy to rot, and the number of times of reuse is small, so it cannot be recycled again. Therefore, now wood formwork has been basically replaced by plastic. Template replaced. In the initial stage of plastic formwork research, new raw materials such as resins and additives were basically used, resulting in high material and manufacturing costs. Later, people began to study adding waste materials to additives to produce templates. [0003] For example, in the patent document with the application number 201310191688.1, the application date is 2013.5.22, and the application publication date is 2013.7.24, a composite plastic template and its preparation method are disclosed, and it is specifically recorded that the ...
