Abstract

The invention discloses a foam stabilizer. The foam stabilizer is prepared from a compound with the structure shown in a formula (1); R1 has the structure shown in a formula (2), m,n are both integers ranging from 0 to 20 and are not 0 simultaneously; R2 represents one of methyl, ethyl, propyl, isopropyl, n-butyl, tertiary butyl and alkyl of C5-C12, and x,y are both integers ranging from 1 to 20. The invention further discloses a preparation method of the foam stabilizer, polyoxyethylene polyoxypropylene, crylic acid or acryloyl chloride, a catalyst, a polymerization inhibitor and a water-carrying agent are mixed to react to generate an intermediate product, and alkoxy polyoxyethylene polyoxypropylene acrylate is obtained; the alkoxy polyoxyethylene polyoxypropylene acrylate is mixed with hydrogen-containing silicone oil and a chlorine platinum acid catalyst, and reacting is performed to obtain the foam stabilizer. According to a polyurethane foaming material prepared through the foam stabilizer, circular bubbles with the uniform size can be obtained, the bubble opening rate is higher, and the collapsed hardness is reduced.

Description

technical field [0001] The invention relates to a foam stabilizer, in particular to a foam stabilizer for preparing polyurethane, and belongs to the technical field of polyurethane material synthesis. Background technique [0002] Polyurethane (PUR) is a polymer with repeating structural units of urethane chain segments made by the reaction of isocyanate and polyol. PUR products are divided into two categories: foamed products and non-foamed products. Foamed products are divided into soft, hard, and semi-rigid PUR foams, sponges, and microcellular elastomers according to their hardness. Among them, soft is the main variety, which has excellent elasticity, softness, elongation and compressive strength, good chemical stability, resistance to many solvents and oils, excellent abrasion resistance, and is 20 times larger than natural sponges. Excellent processability, heat insulation, adhesion and other properties, it is a kind of cushioning material with excellent performance. ...
