Abstract

The fibrous unsaturated polyester putty is one kind of polymer putty. The fibrous unsaturated polyester putty consists of two parts, main fibrous unsaturated polyester putty and curing agent, in the weight ratio of 50. The main fibrous unsaturated polyester putty consists of unsaturated polyester resin 100 weight portions, promoter 2-4 weight portions, styrene 3-5 weight portions, fiber 0.3-0.5 weight portions, stuffing 100-120 weight portions, and pigment 3-5 weight portions. The curing agent consists of initiator 100 weight portions, pigment 3-5 weight portions, and stuffing 1-3 weight portions. The present invention has high strength, high attachment to metal material, convenient use, less shrinkage, fast drying speed, good air drying performance, high compatibility with paint, and fine and smooth film and makes it possible to fill hole as large as 10 mm in once operation.

Description

Technical field: [0001] The invention relates to a polymer putty. Background technique: [0002] Atomic ash is a kind of filling material, its scientific name is polymeric putty, it is mainly used for caulking and filling on the surface of metal and non-metal materials before painting, so as to obtain a flat and smooth appearance. Traditional putty is made of gypsum, calcium carbonate, cooked tung oil, etc., and can also be directly prepared with some paints. Their biggest disadvantages are slow drying speed, large shrinkage rate, poor strength, large solvent volatilization, and environmental pollution. , Harm the health of the operator. Atomic putty is mainly made of unsaturated polyester. It is different from other existing synthetic resin putties in that it can adjust the curing speed with a curing agent and can be cured quickly. Its largest application market is currently mainly for automobile manufacturing and overhaul industry. With the continuous development of the...
