A kind of production process of lightweight composite floor

Abstract

The present invention relates to the technical field of flooring, specifically a production process for lightweight composite flooring, which includes steps in sequence: ( 1 ) Prepare materials according to the structure and efficient production needs; ( 2 ) once bonded to form a U frame; ( 3 ) secondary bonding to form a semi-closed box with openings at both ends; ( 4 ) Polyurethane foam molding, three times of bonding to form a semi-finished composite floor; ( 5 ) Cutting: The semi-finished composite floor is cut into fixed sizes. The lightweight composite floor produced by the present invention has high structural strength, good physical properties, environmental protection, wide application range, high production efficiency, strong controllability and low cost.

Description

technical field [0001] The invention relates to the technical field of floors, in particular to a production process of lightweight composite floors. Background technique [0002] There are many types of flooring in the market, among which solid wood flooring, composite flooring, and bamboo flooring are the most common. They have a wide range of applications and are the focus of people's attention. Moreover, the performance indicators are also improving day by day. However, there are also many problems. The Chinese invention patent that publication number is 101644101 discloses a kind of three-layer waterproof solid wood floor. , the waterproof performance is relatively rough, and it cannot achieve good results. Another example is that the Chinese invention patent with the publication number of 1535813 discloses a polyurethane-hard plastic composite floor. In addition, the texture has also become lighter, but the molding process requires the use of multiple molds, many mold...

Problems solved by technology

[0002]There are various types of flooring in the market, among which solid wood flooring, composite flooring, and bamboo flooring are the most common, with a wide range of applications. The index of performance also improves day by day, but, also there are many problems, discloses a kind of three-layer waterproof solid wood floor as the Chinese invention patent of publication number 101644101, and this floor main body is all solid wood, causes cost height and weight is very big, in Some very high buildings cannot be used as floors. In addition, the waterproof performance is relatively rough and cannot achieve good results. Another example is that the Chinese invention patent with the publication number of 1535813 discloses a polyurethane-hard plastic composite floor , although the water resistance, wear resistance, and adhesion are better, and the texture becomes lighter, but the molding process requires the use of multiple molds, many molding steps, and subsequent demoulding, etc., the entire production time is very long , the efficiency is low, and the probability of problems in the process is also high, which affects production, and the density of the polyurethane surface layer should not be too large. If it is too large, it is easy to deform the low-density plastic bottom layer, so that the density becomes smaller and cannot play a better role. abrasion resistance, adhesion
