Embodiment approach

[0042] As an embodiment of the present invention, the reinforcing layer 11 is made of thermosetting resin, and the thermosetting resin is preferably 5224 high temperature curing epoxy resin;

[0043] During operation, the reinforcing layer 11 is made of a thermosetting resin material. The thermosetting resin is preferably 5224 high temperature curing epoxy resin. The curing reaction of 5224 high temperature curing epoxy resin is 180 degrees Celsius, which is greater than the peak value of the gypsum board during the drying stage. The temperature is 160 degrees Celsius. After the gypsum board is dried and cured, the temperature is heated again to melt the 5224 high temperature curing epoxy resin. The melted 5224 high temperature curing epoxy resin is melted and cured in a temperature space between 180 degrees Celsius and 190 degrees Celsius. During this process, the melted 5224 high temperature curing epoxy resin will penetrate into the surface layer of the board body 1 and then...

Abstract

The invention belongs to the technical field of building decoration materials, and particularly relates to an anti-crack gypsum board which comprises a paper surface layer, a board body, a reinforcing layer and high-melting-point paraffin, the paper surface layer adheres to the outer surface of the board body, so that the paper surface layer forms a protection layer for the board body, the waterproof performance of the board body is improved, and the reinforcing layer is fixedly connected between the board body and the paper surface layer. The reinforcing layer has a waterproof effect, so that external water can be effectively prevented from entering the inner space of the reinforcing layer to be in contact with the plate body, and the water is effectively prevented from eroding the interior of the plate body to damage the structural strength of the plate body; according to the gypsum board, the surface of the paper surface layer is coated with a layer of paraffin, and the paraffin is promoted to melt by utilizing residual heat after drying, so that the paraffin is liquefied and permeates into the paper surface layer, the waterproof performance of the board body can be further improved, and the overall structural strength of the gypsum board is further improved.

Description

technical field [0001] The invention belongs to the technical field of building decoration materials, in particular to a crack-resistant gypsum board. Background technique [0002] Gypsum board is a material made of building gypsum as the main raw material. It is a kind of building material with light weight, high strength, thin thickness, convenient processing, sound insulation, heat insulation and fire resistance. [0003] At present, with the improvement of people's living standards, gypsum boards are used in the decoration of most family houses. There are a variety of plate-shaped and bar-shaped products on the field. The hardness of the gypsum board is low, and the gypsum board is prone to cracks after being used for a period of time, thus affecting the overall structural strength of the gypsum board. Since the main material of the gypsum board is gypsum, gypsum has a certain water absorption. Moisture is easy to occur, and the moisture resistance of gypsum board is ...
