Abstract

The invention discloses polyurethane foaming glue with added large-molecular modified calcium carbonate. The foaming glue is prepared from, by weight, 150-160 parts of diphenyl methane diisocyanate, 100-105 parts of propoxylated glycerin, 100-110 parts of castor oil, 5-6 parts of glycerol, 40-43 parts of diethyl phosphate, a proper amount of 1mol / L sodium hydroxide, 13-15 parts of diatomite, 5-6 parts of distilled water, 2-3 parts of triethanolamine, 3-4 parts of dibutyltin dilaurate, 3-4 parts of alpha-olefin sulfonate, 5-6 parts of simethicone, 9-10 parts of methyl methacrylate, 9-10 parts of butyl acrylate, 0.25-0.26 part of mercaptoethanol, a proper amount of methylbenzene, 0.015-0.02 part of azodiisobutyronitrile and 5-6 parts of nano calcium carbonate. The production process of the product is convenient to control, on-site foaming can be achieved, cost is low, and the prepared foaming glue is good in viscosity, excellent in sealing performance, suitable for sealing of switch cabinets and good in stability.

Description

technical field

[0001] The invention relates to the technical field of styrofoam, in particular to a polyurethane styrofoam added with macromolecule modified calcium carbonate. Background technique

[0002] Two-component polyurethane adhesive is the most important type of polyurethane adhesive, usually composed of A component (main agent) and B component (curing agent), where A component is a hydroxyl component, B component For components containing free isocyanate groups, the two are packaged separately and can be formulated and used in a certain proportion. In our country, the research on foaming two-component polyurethane adhesives began in 1995 and was gradually put into use in the late 1990s. The foaming two-component polyurethane adhesive has the characteristics of porosity, low relative density, and high specific strength. According to different raw materials and formulas, it can be made into ordinary soft foam, hard foam, high-resilience foam and slow-rebound foam. ...
