Embodiment 1

[0041] A high dimensional stability laminate flooring, referred to figure 1 , which includes a wear-resistant surface layer 1, a finish layer 2, a first glass fiber impregnated paper layer 3, a substrate layer 4, a second glass fiber impregnated paper layer 5, a balance layer 6 and a wear-resistant bottom layer 7 arranged in sequence. Among them, the wear-resistant surface layer 1 and the wear-resistant bottom layer 7 are all melamine wear-resistant paper layers; the finish layer 2 is a melamine pattern paper layer; the substrate layer 4 is an SPC substrate, and the surface of the SPC substrate layer is sanded Processing; the balance layer 6 is a balance paper layer. In addition, in the present embodiment, the first glass fiber impregnated paper layer 3 and the second glass fiber impregnated paper layer 5 are all selected with a grammage of 135g / m 2 Fiberglass impregnated paper impregnated with melamine glue.

[0042] refer to figure 2 , its manufacturing process includes ...

Embodiment 2

[0045] A composite floor with high dimensional stability, based on Example 1, the difference between this example and Example 1 is that the gram weights of the first glass fiber impregnated paper layer 3 and the second glass fiber impregnated paper layer 5 are average 80g / m 2 .

[0046] Example: 3:

[0047] A composite floor with high dimensional stability, based on Example 1, the difference between this example and Example 1 is that the gram weights of the first glass fiber impregnated paper layer 3 and the second glass fiber impregnated paper layer 5 are average 20g / m 2 .

Embodiment 4

[0049] A composite floor with high dimensional stability, based on Example 1, the difference between this example and Example 1 is that the gram weights of the first glass fiber impregnated paper layer 3 and the second glass fiber impregnated paper layer 5 are average 60g / m 2 , and the balance layer 6 is a base paper layer of melamine pattern paper.

[0050] Its manufacturing process is as follows:

[0051]Wear-resistant bottom layer 7, balance layer 6, second glass fiber impregnated paper layer 5, substrate layer 4, first glass fiber impregnated paper layer 3, facing layer 2 and wear-resistant surface layer in sequence from bottom to top 1 Mold laid on lamination equipment. Hot pressing is carried out at 140°C and 10MPa, and the hot pressing time is controlled at 50 minutes, so that the composite floor is shaped; after natural cooling, the composite floor is demoulded; after the composite floor is completely cooled and kept healthy for 24 hours, it is placed at 75°C. The c...

Abstract

The invention discloses a high-dimensional-stability composite floor. The high-dimensional-stability composite floor comprises a wear-resisting surface layer, a facing layer, a first glass fiber impregnation paper layer, a base material layer, a second glass fiber impregnation paper layer, a balance layer and a wear-resisting bottom layer which are arranged in sequence. The glass fiber impregnation paper layers are arranged on the front face and the back face of the base material layer, the composite floor size dimensional stability is improved, and particularly, under the humid environment, the dimensional stability is improved. In addition, the invention correspondingly discloses a making process of the composite floor. The process comprises the steps of spreading, hot pressing, demolding and tempering. The making process is simple in step, and the made composite floor has the advantage of keeping the high dimensional stability under the humid environment.

Description

technical field [0001] The invention relates to a composite floor with high dimensional stability and its manufacturing process. Background technique [0002] At present, there are many technologies related to floor manufacturing, for example, the Chinese patent with the application publication number CN1814936A discloses a wear-resistant laminated solid wood floor and a manufacturing method thereof. The solid wood floor has a wear-resistant surface layer, a finish layer, a skeleton impact-resistant layer and a base material layer that are combined from top to bottom. The wear-resistant surface layer is impregnated with melamine formaldehyde resin with a quantitative value of 30-60g / m 2 1. The gummed paper layer is made of single-layer wood pulp paper containing 30-35% aluminum oxide. The veneer layer is a single-layer natural wood slice or rotary slice. The impact-resistant skeleton layer is made of phenolic resin impregnated with whole wood Pulp paper or semi-wood pulp p...
