preparation example Construction

[0040] The preparation method of polyether polyol B1 comprises the following steps: (1) 100 parts by weight of propylene glycol react with 767 parts by weight of ethylene oxide to form low-molecular polyether polyol, the reaction time is 8h, and the reaction temperature is 120°C; ( 2) In step 1, 100 parts of low-molecular polyether polyol and 90 parts by weight of phthalic anhydride are polymerized to form polyol I, the reaction time is 8 hours, and the reaction temperature is 120° C.; (3) 100 parts of polyol I in step 2 React with 93 parts by weight of propylene oxide to form polyether polyol B, the reaction time is 6 hours, and the reaction temperature is 125°C.

[0041] The preparation methods of polyether polyol B2 to polyether polyol B4 were carried out according to the steps in Example 1. The only difference was that the reaction raw materials, reaction types, raw material ratios, reaction time and reaction temperature were different. See Table 2 for details.

Abstract

The invention relates to a composite material for automotive interior skin and its preparation method and application, and mainly solves the problems of low composite fastness, large amount of flame compounding agent used and large odor of the composite material for automotive interior skin in the prior art during flame compounding question. The present invention adopts a composite material for automotive interior skin, which is composed of component I and component II, and the weight ratio of component I to component II is 100:20~60, wherein component I is expressed in parts by weight The count includes polyether polyol A: 30-60 parts, polyether polyol B: 30-60 parts, polymer polyol C: 10-40 parts, water: 1-5 parts, amine catalyst: 0.1-1 Parts, tin catalyst: 0.1 to 1 part, foam stabilizer: 0.5 to 2 parts, flame retardant: 2 to 12 parts, flame compounding agent: 0.5 to 5 parts; component II includes isocyanate 20 to 5 parts by weight 60 parts and the technical scheme of the preparation method thereof have achieved good technical effects and can be used in the industrial production of automotive interior skin composite materials.

Description

technical field [0001] The invention relates to a composite material for automobile interior trim skin and its preparation method and application. Background technique [0002] In the prior art, automotive interior skin composite materials usually use polyurethane automotive flame composite sponges and fabrics or leather composites to be used in automotive interiors; polyurethane automotive flame composite sponges can be mainly divided into polyether sponges and polyester sponges. , The production process of polyether sponge is simple, its performance is slightly worse than that of polyester sponge, and its cost is lower. It is mainly used in low-end models; the production process of polyester sponge has high requirements for equipment, and the produced sponge has good performance and high price. Mainly used in high-end models. [0003] At present, the flame composite sponge with the largest amount on the market is polyether polyurethane sponge, that is, the main raw materi...
