Problems solved by technology

However, the strength of polyurethane foam is relatively poor. In order to improve the strength of polyurethane foam, it is usually necessary to add some high-strength particles or nano powders to polyurethane foam. The former has a certain negative impact on the uniformity of polyurethane foam material. The latter will increase the cost of polyurethane foam more

Embodiment Construction

[0011] The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0012] As an embodiment of the present invention, the high-strength polyurethane foam consists of the following materials in parts by weight: 50-60 parts of deionized water, 50-60 parts of isocyanate, 30-50 parts of polypropylene glycol, polydimethyl 20-30 parts of siloxane, 10-20 parts of curing agent.

[0013] Further, the isocyanate is alkylphenyl diisocyanate.

[0014] Further, the alkyl group of the alkylphenyl diisocyanate is a linear alkyl group.

[0015] Further, the alkylphenyl diisocyanate is C1-C6 alkylp...

Abstract

The invention discloses a high-intensity polyurethane foam plastic, which is prepared from the following substances in parts by weight: 50 to 60 parts of deionized water, 50 to 60 parts of isocyanate,30 to 50 parts of polypropylene glycol, 20 to 30 parts of polydimethylsiloxane and 10 to 20 parts of curing agents. The high-intensity polyurethane foam plastic has the advantages that the high-viscosity polydimethylsiloxane is used for performing polyurethane crosslinking; the zinc carbonate curing agents are used for curing the polyurethane foam plastic; the high-viscosity polydimethylsiloxaneand the zinc carbonate form powerful crosslinking in the polyurethane molecules, so that the intensity of the polyurethane foam plastic can be effectively improved.

Description

technical field [0001] The invention relates to the field of plastics, in particular to a high-strength polyurethane foam. Background technique [0002] Polyurethane foam is an important structural material because of its light weight and good thermal insulation effect. However, the strength of polyurethane foam is relatively poor. In order to improve the strength of polyurethane foam, it is usually necessary to add some high-strength particles or nano powders to polyurethane foam. The former has a certain negative impact on the uniformity of polyurethane foam material. The latter will increase the cost of polyurethane foam more. Therefore, it is of great significance to develop a polyurethane foam with high strength, uniform texture and little increase in cost. Contents of the invention [0003] The technical problem mainly solved by the invention is: the strength of the polyurethane foam plastic is relatively low, and there is no product formula for improving the stren...
