A kind of surface wear-resistant extruded floor and its production process

Abstract

The invention discloses a surface wear-resistant extrusion molding floor and a production process thereof, comprising an inner floor, an inner shell, an outer shell, an anti-slip pad and anti-slip textures. , Install the center buffer between the center substrates, set the left sleeve and left auxiliary spring and the right sleeve and the right auxiliary spring in the outer inner casing and the outer casing respectively, and make them embedded in the inner layer of the floor respectively In the side buffer grooves at both ends, when the floor is installed and subjected to external impact, the buffer corrugated pads and buffer springs on the upper and lower sides of the adjustment rod in the central buffer piece cooperate to reduce the impact strength in the vertical direction. The auxiliary spring and the right auxiliary spring reduce the impact strength in the horizontal direction, and effectively improve the impact resistance in the horizontal and vertical directions while ensuring the wear resistance of the surface.

Description

technical field [0001] The invention relates to the technical field of extruded flooring, in particular to a wear-resistant extruded flooring with a skin and a production process thereof. Background technique [0002] Wear-resistant floor is also called practical floor and durable floor. During the production process, the floor is pressed and formed by U-shaped groove hot-pressed steel template to make it concave and convex and natural and real. At the same time, the edge of the floor surface is specially designed according to the optical principle of color. A "solid wood visual line" makes the floor visually have a solid wood U-shaped groove, which not only avoids the defects of traditional V-shaped grooves that are not wear-resistant and difficult to clean, but also creates the overall effect of large-area logs and wear-resistant floors It is usually prepared by extrusion molding.

Problems solved by technology

[0002] Wear-resistant flooring is also called practical flooring and durable flooring. During the production process, the floor is pressed and formed by using U-shaped groove hot-pressed steel templates to make it concave and convex and natural and real. At the same time, the edge of the floor surface is specially designed according to the optical principle of color. A "solid wood visual line" makes the floor visually have a solid wood U-shaped groove, which not only avoids the defects of traditional V-shaped grooves that are not wear-resistant and difficult to clean, but also creates the overall effect of large-area logs and wear-resistant floors It is usually prepared by extrusion molding. Extrusion molding refers to the method of forcefully extruding plastic clay to form it through a hole die. Both extrusion molding and plastic molding use plastic clay. The difference between the two is extrusion molding. Extruders that require strong extrusion are powered by hydraulic pressure, compressed air or mechanical pressure. They are mostly used in the production of special refractory materials. They must be plasticized before extrusion molding, usually by adding plasticizers or bonding Dextrin, industrial syrup, carboxymethyl cellulose, polyvinyl acetate, polyethylene drunk and other organic plasticizers are commonly used in industrial production. The wear-resistant floor prepared by the existing extrusion molding process, Its surface has strong wear resistance, but because it is formed at one time, its overall brittleness is high, resulting in poor impact resistance during normal use.
