Embodiment 1

[0040] A kind of microfoam plastic floor, refer to figure 1 As shown, it includes a layer of base material layer 1. The base material layer 1 is formed by physical foaming method of plastic raw material. The plastic raw material can be selected from any one of PVC, PE, and PP. One of the plastic raw materials is weighed Then it is added to the barrel of the injection molding machine and plasticized under the shear force of the screw of the injection molding machine and the heating of the heating ring. At this time, the physical foaming agent is directly injected into the end of the melting section of the screw and mixed evenly with the melt formed by the plastic raw material, and then High pressure and high speed are injected into the mold cavity, and the pressure is suddenly reduced in the mold cavity, so that a large amount of supersaturated gas in the melt is separated out, thereby forming a microporous substrate layer 1. The diameter of the cells in the substrate layer 1 is...

Embodiment 2

[0043] A microfoamed plastic floor, the difference from Embodiment 1 is that with reference to figure 2 As shown, a surface layer 2 is compounded on the upper surface of the substrate layer 1 by bonding or hot pressing, and the surface layer 2 is a transparent wear-resistant layer 21 made of PVC material.

Embodiment 3

[0045] A microfoamed plastic floor, the difference from Embodiment 1 is that with reference to image 3 As shown, a surface layer 2 is laminated on the upper surface of the substrate layer 1 by bonding or hot pressing. The surface layer 2 is a color filter layer 22 made of PVC material, and ink patterns are printed on the color filter layer 22 .

Abstract

The invention discloses a micro-foaming plastic floor and a production technology thereof, and relates to the field of floors. The micro-foaming plastic floor comprises a base material layer formed through a physical foaming method, and the base material layer is selected from a plastic raw material, wherein the plastic raw material is one of PVC, PE and PP; a surface layer is compounded on the upper surface of the base material layer, and the surface layer comprises one or more of an abrasion-resistant layer and a color film layer; and a non-woven fabric is compounded on the upper surface ofthe base material layer. The production technology comprises the following steps of A, blending, B, extrusion molding, and C, compounding. According to the micro-foaming plastic floor and the production technology thereof, the lightweight floor can be achieved, and the foot feel is improved in the using process.

Description

technical field [0001] The invention relates to the field of floors, in particular to a microfoamed plastic floor and a production process thereof. Background technique [0002] Plastic flooring is a new type of light-weight floor decoration material that is very popular in the world today. It is widely used, such as indoor homes, hospitals, schools, office buildings, factories and other places. [0003] Chinese Patent Publication No. CN 103195228A discloses a sound-absorbing and heat-insulating floor and its processing method. The floor includes a surface layer and a bottom layer, the bottom layer is attached below the surface layer, the surface layer includes a PVC sheet layer, and the bottom layer includes PVC foam Coiled material layer, PVC foamed coiled material layer is a foamed coiled material layer added with glass fiber felt, glass fiber mesh or non-woven fabric, among which PVC foamed coiled material is foamed in high temperature foaming by using chemical foaming p...
