Abstract

The invention discloses a plasticizer-free micro-foaming PVC (polyvinyl chloride) floor which sequentially comprises a PVC hard transparent sheet bottom layer, a rigid micro-foaming SPC (styrene-butadiene-styrene) base material, a PVC printing layer and a PVC hard transparent sheet surface layer from bottom to top, wherein the PVC hard transparent sheet bottom layer and the PVC hard transparent sheet surface layer do not contain plasticizers. The invention further discloses a preparation method of the micro-foaming PVC floor without the plasticizer. In the use process of the PVC plastic floor, people do not need to worry about harm to the human body and the environment due to migration, diffusion and precipitation of a plasticizer; besides, according to the rigid micro-foaming SPC base material prepared by the invention, the rigidity of the product is ensured, the use size stability of the product is ensured, and meanwhile, the foam holes or the expandable microspheres uniformly distributed in the base material have the effects of shock absorption, buffering, sound absorption, noise reduction and the like.

Description

technical field [0001] The invention belongs to the field of floors, and in particular relates to a micro-foamed PVC floor without plasticizer and a preparation method thereof. Background technique [0002] PVC flooring is a new type of light-weight ground decoration material that is very popular in the world today, also known as "light-weight ground material". It is a popular decorative product in Europe, America, Asia, Japan and South Korea. It is popular abroad. It has entered the Chinese market since the early 1980s. It has been widely recognized in large and medium-sized cities in China and is widely used, such as homes and hospitals. , schools, office buildings, factories, public places, supermarkets, commercial and other places. "PVC floor" refers to the floor made of polyvinyl chloride material. Specifically, polyvinyl chloride and its copolymer resin are used as the main raw materials, and fillers, plasticizers, stabilizers, colorants and other auxiliary materials...
