Abstract

The invention relates to the technical field of high polymer materials, in particular to an impact-resistant PVC board. A pure hard PVC product is crisp, the notch impact strength is only 2.2 kJ/m<2>,brittle rupture is extremely likely to happen when the product is impacted, and use of the product as a structural material is limited. Based on the problem, the invention provides an impact-resistant PVC board. A self-made modified ACR impact modifier is added into a material system, a small amount of SiO2 particles are introduced into a modified ACR shell layer material, so that the surface roughness of the shell layer material is increased to a certain extent, the effect of timely stopping excessive development of crazes can be achieved, destructive cracks are prevented from being formed,the purpose of greatly improving the impact strength of the material is achieved, and good commercial prospects are achieved.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to an impact-resistant PVC board. Background technique [0002] Polyvinyl chloride (PVC for short) resin, together with polyethylene, polypropylene, polystyrene and ABS resin, are collectively referred to as the five general-purpose resins. PVC resin has excellent physical and chemical properties, which are mainly reflected in the following aspects: (1) Strong corrosion resistance and stable chemical properties; (2) Excellent flame retardancy and insulation resistance; (3) Good plasticity, PVC resin is a thermoplastic resin, which can be prepared by various molding and processing methods to meet various needs. , At the same time, the uncrosslinked PVC resin can be recycled and reused. (4) Excellent wear resistance, PVC products can be widely used as wear-resistant floors, wear-resistant pads and anti-corrosion and wear-resistant coatings. [0003] Although PVC resin has g...
