Wear-resistant PVC roll material and preparation method thereof

Abstract

The invention discloses a wear-resistant PVC roll material comprising PVC resin, composite resin, TPU resin, an antioxidant, a modified plasticizer, a stabilizer, a filling agent and a foaming agent;the composite resin comprises modified ABS resin, inorganic nano-ceramic resin, vinylidene fluoride homopolymer resin, ultra-high molecular weight polyethylene resin and ethylene-vinyl acetate copolymer; and the modified plasticizer comprises the components according to the weight ratio: dioctyl phthalate, 2-ethylhexyl epoxystearate, dioctyl azelate, epoxybean oleic acid 2-ethylhexyl ester and ethylene butyl acrylate-glycidyl ester. The prepared wear-resistant PVC roll material has the effects of use convenience, high wear resistance and higher environment friendliness.

Description

technical field [0001] The invention relates to a PVC floor material which can be used for trains, office buildings and hospitals, in particular to a wear-resistant PVC coiled material and a preparation method thereof. Background technique [0002] A large number of PVC transparent coils are used in public places with super high flow of people, which have very high requirements for wear resistance. Among them, they are mainly used in high-end office buildings for floor boards, which can increase friction and reduce cracking. It is used in hospitals or some public places with dense traffic. When food or some difficult-to-clean compounds drip on the bottom plate, it can be easily wiped off with a rag, which is very convenient and can maintain a long-term cleaning effect.

Problems solved by technology

[0003] PVC is well known as a very common plastic material, its full name is polyvinyl chloride. In recent years, the development of PVC is mainly used in pipes. It can perfectly replace metal pipes and be installed in every household, but PVC is on the bottom plate. The application of PVC is still in its infancy, and the material has just emerged in recent years, and the PVC on the market is initially granular and then shaped through thermoplastic extrusion and other processes, and then processed into a plate-like structure that can be bent arbitrarily, but There are very high requirements for the wear resistance level. Although the wear resistance of the PVC resin coil with a high proportion (greater than 65%) can reach the T level, the excessively high proportion not only increases the difficulty of processing, but also increases the processing difficulty. The dimensional change rate of the floor heating is relatively large, which cannot meet the standard requirements. After all, coiled materials are used in densely populated areas. This requires more attention to the wear resistance of the surface of the coiled material. If the wear resistance is not good, pits or damage will appear after a long time, which is serious. It affects the use, and most of the PVC coils on the market are multi-layer structures. Among them, the patent number CN200710118914.8 discloses an improved PVC elastic coil floor and its production method. Although a wear-resistant layer is provided, there are technical requirements and The cost of raw materials is relatively high, and it can only be used in some special places, but it cannot be widely promoted
