Abstract

The invention provides a preparation method for a self-adhesive PVC floor. The self-adhesive PVC floor comprises a PVC substrate layer, a UV treatment layer, an adhesive layer and a protective paper layer. The preparation method comprises the following steps: S1, preparation of the PVC substrate layer; S2, preparation of the UV treatment layer; S3, preparation of a rough friction surface; S4, preparation of protective paper; and S5, preparation of the adhesive layer. According to the invention, an acrylate emulsion is polymerized by adopting acrylic acid and methacrylic acid with a mass fraction of 2% to 5%, so oil resistance, solvent resistance and adhesive strength of the acrylate emulsion are significantly improved; freeze-thaw stability of the emulsion and wettability of the emulsion to a pigment filler can be improved; the polymerized emulsion can be endowed with the characteristic of thickening; meanwhile, through addition of different varieties of filling materials with different parts by mass and various auxiliary agents with different parts by mass, a floor adhesive is optimized; a PVC floor adhesive with good initial viscosity and high bonding strength is prepared; and the service life of a PVC floor is prolonged.

Description

technical field [0001] The invention relates to the technical field of floor technology design and application, in particular to a preparation method of a self-adhesive PVC floor. Background technique [0002] With the progress of society and the development of science and technology, people have higher and higher requirements for the living environment, especially the building and decoration materials used in residential places.” There are many new energy-saving and environmentally friendly building materials on the market, among which polyvinyl chloride (PVC) Plastic flooring is currently the most novel high-tech flooring material in the world's building materials industry. It has entered the Chinese market since the early 1980s and has been widely recognized in large and medium-sized cities in China. It is widely used, such as indoor homes and hospitals. , schools, office buildings, factories, public places, supermarkets, stadiums and other places. [0003] However, the ...
