Problems solved by technology

This kind of processing technology is not easy to control, the production process is long, the amount of stabilizer is large, and the material heating time is long.
The PVC laminated thick film produced by this processing technology has poor transparency and brightness, and the color of transparent light-colored products is difficult to control, and it is difficult to achieve the appearance standard of white, transparent and bright white light laminated thick film.

Abstract

The invention relates to a white-light laminated crystal board and a making method thereof. The white-light laminated crystal board comprises the following ingredients: 100 polyvinyl chloride, 40-60 dioctyl phthalate, 1.6-2.5 liquid barium-cadmium-zinc stabilizers, 0.1-0.6 acrylic acid processing assistant, 0.03-0.08 pigment and 0.2-0.6 PHR of non-toxic phosphate. The making method comprises the following procedures of automatic metering, high-speed mixing, cooling and stirring, plastification by using a planetary extrusion machine, filtering, four-roller calendaring, calendaring and cooling, bait remaking, calendaring and reeling, laminating and feeding, preheating and laminating, lamination cooling and trimming, lamination reeling, and packaging and warehousing of finishing products. The product has better elasticity than that of glass and has high surface transparency and illumination, the surfaces of films have good flatness and small water wave, a single laminated film approaches to be colorless, and the films have high transparency.

Description

Technical field [0001] The invention belongs to a polyvinyl chloride calendered and laminated crystal plate, in particular to a white light laminated crystal plate that is similar to glass, has small water lines, and can achieve white, transparent and bright appearance effects 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, which generally requires 160-210°C to be processed. In addition, the substituted chlorine group contained in the molecular structure of PVC easily leads to the dehydrochlorination reaction of PVC resin, thereby causing the degradation reaction of PVC. PVC is extremely unstable to heat, and temperature rise will greatly promote the dehydrochlorination reaction of PVC. The characteristic is a series of transparent Color changes from c...
