Abstract

A urea resin formaldehyde thermal-insulating composite powder and its production are disclosed. The composite powder consists of urea formaldehyde plastic 60-90 proportion, cellulosine or straw powder 5-20 proportion, fibrous glass 0.5-6 proportion, asbestos 1-8 proportion, gypsum 1-8 proportion, silicate 0.1-1.5 proportion and glycerin 0.5-3 proportion. It has excellent strength, fire-retardant and insulating performances. It can be used to substitute plastics, ceramics, cast iron and glass fiber reinforced plastics to produce pipes, flanged disk, valve and pump.

Description

technical field [0001] The invention relates to a urea-formaldehyde resin foam thermal insulation composite powder and a preparation method thereof, as well as a composite board synthesized by die-casting using the powder and a synthesis method thereof. Background technique [0002] Urea-formaldehyde resin powder (UF), also known as electric jade powder, is composed of urea-formaldehyde resin, glass fiber and other fillers, stearic acid and other lubricants, hexamethylenetetramine and other stabilizers, urea or thiourea and other plasticizers, pigments, etc. The components are mixed and processed. It is usually made by impregnating cellulose filler with urea-formaldehyde resin aqueous solution, and then drying, crushing, ball milling, sieving and other processes. Electric jade powder is widely used in electrical appliances, meters, wiring appliances, electrical parts, electrical casings, telephone accessories, electrical switches, plugs, buttons, chess, cards, toys, bottle ...
