Abstract

The invention provides a urea-formaldehyde resin-based composite material. The urea-formaldehyde resin-based composite material comprises, by weight, 40 to 60 parts of urea-formaldehyde resin, 6 to 8 parts of PPS, 3 to 4 parts of a compatilizer, 8 to 10 parts of alumina hollow microsphere, 2 to 5 parts of a flexibilizer, 15 to 20 parts of a filling material, 1 to 2 parts of a coupling agent, 1 to 2 parts of a curing agent, 0.5 to 1 part of pigment, 1 to 2 parts of a lubricant and 3 to 5 parts of a stabilizing agent. The invention also provides a preparation method for the composite material. The urea-formaldehyde resin-based composite material for skis has good toughness, hydrolysis resistance and heat resistance and can be applied to a plurality of occasions.

Description

Technical field: [0001] The invention relates to a composite material, in particular to a urea-formaldehyde resin-based composite material and a preparation method thereof. Background technique: [0002] Urea-formaldehyde resin, also known as urea-formaldehyde resin, abbreviated as UF, is the polycondensation of urea and formaldehyde under the action of a catalyst (alkaline or acidic catalyst) into an initial urea-formaldehyde resin, and then under the action of a curing agent or an auxiliary agent, it forms an insoluble, insoluble resin. Melting end-stage thermosetting resin. The color of cured urea-formaldehyde resin is lighter than that of phenolic resin, translucent, resistant to weak acid and weak alkali, good insulation performance, excellent wear resistance, and cheap. In 1924, it was developed by the British cyanamide company, and the product was sold in 1928. The output reached 1,000 tons in the mid-1930s, and the world's annual output exceeded 1.5Mt in the 1980s. ...
