Abstract

The invention discloses a transparent anti-impact hard PVC particle composition and a preparation method thereof. The transparent impact-resistant hard PVC particle composition is characterized in that vinyl chloride-vinyl acetate-butyl acrylate ternary copolymerized resin is used as a bridging agent and cooperates with other modifiers, then mixed granulation is performed to obtain the transparent anti-impact hard PVC particle composition; the composition comprises the following components in parts by weight with each 100 parts by weight of PVC as the benchmark: 100 parts of polyvinyl chloride, 8-15 parts of an anti-impact modifier, 0-4 parts of a bridging agent, 1-3 parts of a heat stabilizer, 2-3 parts of a plasticizer, 0.3-0.8 part of a lubricant, and 0.1-0.3 part of a color toner. By selection of the particle size of anti-impact modifier colloidal particles and introduction of the vinyl chloride-vinyl acetate-butyl acrylate ternary copolymerized resin as the bridging agent, the transparent anti-impact rigid PVC particle formula is improved, the purpose of improving the impact resistance and transparency of the material is finally reached, and the requirements of high-quality transparent anti-impact hard PVC products on high transparency and high impact resistance are met.

Description

technical field [0001] The invention relates to the field of transparent anti-impact rigid PVC granules, more specifically, it relates to a transparent anti-impact rigid PVC granule composition and a preparation method thereof. Background technique [0002] Polyvinyl chloride (PVC for short) is one of the most widely used polymer materials, because it is non-toxic, transparent, easy to process and shape, especially the secondary molding has good air tightness and colorability, and has good physical properties etc., all aspects can meet the requirements as packaging materials, widely used in the field of packaging. However, PVC has poor toughness and is a brittle material. At the same time, its melt viscosity is high, and it is easy to decompose when heated, and the processing temperature is close to the decomposition temperature. , stabilizer, lubricant, toner and other second and third component processing aids to modify it. [0003] In the transparent impact-resistant ri...
