Hard PVC floor production technology

Abstract

The invention discloses a hard PVC floor production process, which comprises the following steps: 1) mixing materials; 2) banburying; 3) opening practice; 4) cutting; 5) hot pressing; Fire; 8) health preservation; 9) cutting board slotting; 10) health preservation; 11) packaging. In the hard PVC floor production process of the present invention, the PVC base plate is made of hard PVC foam material, which can effectively prevent deformation, increase strength and prevent collapse while effectively controlling the shrinkage rate.

Description

technical field [0001] The invention relates to the technical field of PVC flooring, in particular to a production process for hard PVC flooring. Background technique [0002] With the development of the country's economy, the supply of timber has become more and more tense. The main reason is that the forest coverage rate in our country is low. After decades of deforestation, large forests have become bare mountains. Government departments have begun to strictly prohibit logging, which has led to a significant reduction in the supply of timber and rising prices. Internationally, with the reduction of forest resources and the enhancement of environmental protection awareness, countries have also formulated relevant policies to restrict logging and export, resulting in fewer and fewer sources of wood panels and more expensive prices. In addition, wooden boards are prone to formaldehyde pollution in construction and home decoration, which is harmful to human health. Therefor...
