Base plate for integral bathroom wall panel and manufacturing method thereof

Abstract

The invention discloses a base plate for an integral bathroom wall panel and a manufacturing method thereof. The base plate comprises the components of, by weight, 90-110 parts of thermoplastic polymer PVC materials, 50-250 parts of fillers and 0.5n-0.7n parts of additives, wherein n is a natural number greater than or equal to 1 and denotes the type of the additives. Butting grooves which are matched with each other are arranged on the butting sides of two sides of the base plate. During manufacturing, the components are selected according to parts by weight, and the components are heated to115-125 DEG C for heat mixing first, and cooled to below 45 DEG C to be mixed and stirred evenly; a PVC extruder is used for being matched with a designed finished product die for heating extrusion; and sizing and cooling are performed by using vacuum under the traction of a tractor. The base plate can achieve quick butting, is convenient in installation and uniform and attractive in butting joints, and can be recycled; and good surface adhesion and convenient decoration are achieved. The manufacturing method adopts an extrusion process, can produce the base plate with high strength, a stablestructure, environmental protection, recyclable property, waterproof, fireproof and convenient installation for bathroom wall panels.

Description

technical field [0001] The invention relates to a substrate for an integral bathroom wall panel and a manufacturing method thereof, belonging to the technical field of wall substrates. Background technique [0002] At present, the wall panels used in prefabricated integral bathrooms generally use SMC materials, and SMC materials have the following problems in the actual production and use process: [0003] 1. SMC adopts molding production process. This process is limited by the mold. The finished product is single-layer and has low strength. It needs to be reinforced with steel pipes during installation; [0004] 2. There is no docking groove on the butt joint edge of the board and the board, and a special butt joint strip is required between the board and the board, which is very inconvenient to install and affects the appearance of uneven joints; [0005] 3. The material is not recyclable, and a large amount of use will not only waste social resources, but also increase t...

Problems solved by technology

[0003] 1. SMC adopts molding production process. This process is limited by the mold. The finished product is single-layer and has low strength. It needs to be reinforced with steel pipes during installation;

[0004] 2. There is no docking groove on the butt joint edge of the board and the board, and a special butt joint strip is required between the board and the board, which is very inconvenient to install and affects the appearance of uneven joints;

[0005] 3. The material is not recyclable, and a large amount of use will not only waste social resources, but also increase the burden of environmental protection on the society;

[0006] 4. The surface adhesion is poor, and the cost of surface decoration is high
