Problems solved by technology

This processing technology has a long production process, is not easy to control, requires a large amount of stabilizer, and takes a long time to heat the material.
The low-toxic PVC laminated thick film produced by this processing technology has poor transparency and brightness, and it is more difficult to control the color of transparent light-colored products. It is difficult to achieve white, transparent and bright low-toxic white laminated sheets that comply with REACH regulations. Thick slice appearance standard

Abstract

The invention discloses an environment-friendly low-toxicity white-light gluing crystal board and a manufacture method thereof. The formula of the crystal board comprises the following components: 100 polrvinyl chloride, 40-60 diisononyl ortho-phthalate, 1.8-2.5 liquid Ba-Zn stabilizer, 0.3-0.6 acrylicacid processing aid, 0.05-0.08 pigment and 0.3-0.6 PHR nontoxic phosphate. The process comprises the following working procedures of automatically metering; mixing at a high speed; stirring by cooling; plasticizing by using a planet extruder; filtering; four-roll calendaring; calendaring and cooling; bait reusing; calendaring and winding; gluing and feeding; gluing, preheating and gluing; gluing, cooling and cutting edge; gluing and winding; and packing and put finished products in storage. The invention accords with the REACH regulatory requirements and has short process flow, less material plasticizing and processing time and high production efficiency. The environment-friendly low-toxicity white-light gluing crystal board has superior elasticity to glass, high surface transparency and brightness, good surface planeness and small water wave; in addition, a single gluing film is approximate to be colorless, has high transparency and has the characteristics of glass.

Description

technical field [0001] The invention belongs to a polyvinyl chloride calendered and laminated crystal plate, in particular to an environmentally friendly low-toxicity white light laminated crystal plate that meets the requirements of REACH regulations, is similar to glass, has small water marks, and can achieve white, transparent and bright appearance effects and its production method. Background technique [0002] Polyvinyl chloride (hereinafter referred to as PVC) resin is a kind of strong polar polymer, and its intermolecular force is large, which leads to higher softening temperature and melting temperature of PVC resin, and generally requires 160-210°C to process. In addition, the substituted chlorine groups contained in the molecular structure of PVC can easily lead to the dehydrochlorination reaction of PVC resin, thereby causing the degradation reaction of PVC. PVC is extremely unstable to heat, and the temperature rise will greatly promote the dehydrochlorination re...
