Abstract

The invention belongs to the technical field of polyurethane synthetic materials, and particularly relates to a novel polyurethane composite material for wall decoration and a preparation method thereof. The novel polyurethane composite material for wall decoration comprises a component A and a component B. The component A is prepared from the following raw materials in percentage by mass: 10-40 percent of polyether polyol a, 40-70 percent of polyether polyol b, 0-40 percent of polyether polyol c, 0.2-2.0 percent of auxiliary agent, 0.2-1.0 percent of catalyst and 2.5-3.5 percent of water; andthe component B comprises the following raw materials in percentage by mass: 60-100% of polyisocyanate and 0-40% of a plasticizer. The polyurethane material prepared by the invention has higher bearing property and low raw material cost and is energy-saving and consumption-reducing. The invention also provides a simple and feasible preparation method.

Description

technical field [0001] The invention belongs to the technical field of polyurethane synthetic materials, and in particular relates to a novel polyurethane composite material for wall decoration and a preparation method thereof. Background technique [0002] As polyurethane gradually enters people's lives, its use is becoming more and more extensive. For some entertainment places such as KTV, bars and other places, in order to achieve sound absorption and safety protection, some polyurethane products with higher rebound effect are usually used. Good product for interior wall decoration. [0003] At present, most of the wall interior materials commonly used in the market are high-resilience products, which are not strong enough, and require a certain amount of support from the outer layer of auxiliary materials; at the same time, the cost of this product is relatively high, resulting in a certain waste of resources. Contents of the invention [0004] Aiming at the deficienc...
