Problems solved by technology

The existing polyurethane foam TV background wall is mostly made of TDI. This kind of polyurethane TV background wall is easy to produce volatile gas and cause health damage to the human body. However, the polyurethane foam made of modified MDI is equally A large amount of foaming agent has a large foaming density, and the price of modified MDI is high, which increases the cost of the TV background wall

Abstract

The invention discloses polyurethane for a television background wall, as well as a preparation method of polyurethane, belonging to the field of building decoration engineering and particularly relating to a wall surface covering for surface protection. The polyurethane for the television background wall is prepared from the following components in parts by weight: 60-80 parts of polyether polyol, 40-20 parts of polymer polyol, 1.5-3.5 parts of water, 0.5-1.0 part of foam stabilizer, 0.5-3 parts of hole opening agents, 0.11-0.88 part of a catalyst, 1-2 parts of cross-linking agents and 35-40 parts of polymethylene polyphenyl polyisocyanate. The prepared polyurethane is non-toxic, healthy, environmental friendly and low in cost.

Description

technical field [0001] The invention belongs to the field of building decoration engineering, and in particular relates to a wall covering for surface protection. Background technique [0002] The TV background wall is a concept introduced from the decoration of public buildings. It mainly refers to the main wall in the living room, office, and bedroom that can reflect your own image and style. The TV background wall is one of the key points of the decoration of the living room background wall. It occupies a very important position in the design of the background wall. The TV background wall is usually used to make up for the emptiness of the background wall of the TV area in the home space, and at the same time play a role in decorating the background wall of the TV area. . [0003] Glass, wooden materials, paint, tiles, stones, polyurethane foam and other materials can be used as TV background walls. Polyurethane foam is also a common material for TV background walls bec...
