Abstract

The invention discloses a one-time PVC (Polyvinyl Chloride) floor heating, pasting and embossing method for manufacturing a floor which is free of formaldehyde and in addition capable of preventing mold, dampness, fire and insects. The method specifically comprises the following steps: 1) preparing materials, wherein a PVC floor comprises the following raw materials in parts by weight: 145-155 parts of calcium carbonate, 45-55 parts of a PVC powder, 3-5 parts of an ACR (Acrylic Acid) resin, 3-5 parts of a stabilizer, 0.5-0.7 part of an external lubricant, 0.6-0.8 part of an internal lubricant,3-5 parts of an antishock aid and 2-4 parts of a processing aid; 2) mixing the materials; 3) carrying out extrusion; 4) cutting; 5) carrying out UV (Ultraviolet) tempering treatment on the surface ofa base material obtained in the step 4); 6) processing connecting parts. The one-time PVC floor heating, pasting and embossing method disclosed by the invention is particularly applicable to production of PVC floors.

Description

technical field [0001] The invention relates to the technical field of PVC flooring, in particular to a one-time heating and embossing method for PVC flooring. Background technique [0002] With the vigorous development of our country's economy, the demand for timber is increasing, and the forest coverage rate in our country is already low, coupled with the deforestation in recent years, this has led to a decrease in the supply of timber year by year, and the price has also decreased. climbing year by year. Therefore, my country put forward the requirement of "replacing wood with plastic" as early as the 1980s. [0003] PVC flooring is a new type of light-weight floor decoration material that is very popular in the market, also known as "light-weight material". It is a very popular product in Europe, America and Asia, and is popular at home and abroad. It entered China in the 1980s and has been widely recognized in large, medium and small cities in China. [0004] At pres...
