PVC (polyvinyl chloride) floor and production process thereof

Abstract

The invention discloses a PVC (polyvinyl chloride) floor which comprises a bottom layer, a middle layer, an ink jet basic layer, an ink jet layer, a UV (ultraviolet) abrasion resistant primer layer and a UV scratch-resistant top coat layer, wherein the bottom layer, the middle layer, the ink jet basic layer, the ink jet layer, the UV abrasion resistant primer layer and the UV scratch-resistant top coat layer are successively distributed from bottom to top. The production process of the PVC floor provided by the invention comprises the steps of: a. pasting the ink jet basic layer on a composite layer formed by the bottom layer and the middle layer; b. printing the ink jet layer on the ink jet basic layer; c. roller-coating the UV abrasion resistant primer layer on the ink jet layer; d. roller-coating the UV scratch-resistant top coat layer when the UV abrasion resistant primer layer is half-dry; and e. embossing or not embossing the UV scratch-resistant top coat layer through a roller or a track. The PVC floor and production process provided by the invention have the following beneficial effects: a colour film needs not pressing and pasting at high temperature, thereby preventing the colour film from getting yellow, reducing the defects of colour film overstock and short colour film effective period in the current production process by using the ink jet layer to replace the colour film and improving the use defect that the PVC floors on the market at present can not resist scrape; and the PVC floor has easily controlled quality, saves manpower and material resources and has high production efficiency and low investment.

Description

technical field [0001] The invention relates to a stone-plastic floor and its production process, in particular to a stone-plastic floor and its production process that saves manpower and material resources, has high production efficiency, small investment, and easy quality control. Background technique [0002] At present, solid wood flooring is generally used for house decoration. Due to its natural wood texture, solid wood flooring has beautiful and natural annual ring textures and wood colors of various tree species. More and more raw materials cannot meet the needs of the market, so the price of solid wood flooring is very expensive; on the other hand, solid wood flooring has poor wear resistance, and is easy to deform and crack, and it is prone to unevenness during installation. In order to solve the above problems, we have produced imitation direct printing or inkjet stone-plastic flooring with more realistic wood grain or other ground material patterns on the layout....
