Abstract

The invention relates to a low-toxicity white-light glued crystal board and a manufacturing method thereof. The crystal board comprises the following materials: 100 polyvinyl chloride, 40-60 dioctyl phthalate, 1.8-2.5 liquid barium-zinc stabilizer, 0.2-0.6 crylic acid processing agent, 0.05-0.08 pigment and 0.3-0.6 PHR nontoxic organic phosphate. A process comprises the following processes of: anautomatic metering process, a high-speed mixing process, a cooling and stirring process, a planet extruder plastifying process, a filtering process, a four-roller calendering process, a calendering cooling process, a bait recycling manufacture process, a calendering winding process, a gluing material feeding process, a gluing and preheating gluing process, a gluing and cooling edge cutting process, a gluing winding process and a finished product packaging and warehousing process. The invention meets the requirements of EN71Part3, RoHS and PAHs in European Union and standard ASTM F963-08 in America and has the advantages of elasticity superior to that of glass, high surface transparency and brightness, good planeness and small water wave of a membrane surface, approximately colourless single gluing membrane and characteristics of the glass.

Description

technical field [0001] The invention belongs to a polyvinyl chloride calendered and laminated crystal plate, in particular to a glass-like glass that meets the requirements of 4.3.5.2 in the European Union EN71Part3, RoHS, PAHs and American standard ASTM F963-08, with small water marks and can achieve whiteness, A low-toxicity white light laminated crystal plate with a transparent and bright appearance effect and a manufacturing method thereof. 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 temp...
