Abstract

A metal atomic ash consists of main ash and curing agent with weight ratio100:2. The main ash consists of unsaturated polyester resin: 100, improver: 3-5, phenylethylene: 3-5, filling: 120-130,and metal powder: 8-12. The curing agent consists of initiator: 100 and filling: 8-10. The production is carried out by taking special resin or special mixed resin as matrix material, and adding metal powder( iron powder, aluminum powder and copper powder etc. ) besides universal pigment and filling( titanium pigment, bentonite, French white, china clay powder, coarse whiting, and gas-phase silicon dioxide ). It achieves good combing ability, higher hardness and strength of atomic ash.

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 leveling 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 putty in that it can adjust the curing speed with curing agent and can cure quickly. Its largest application market is currently mainly for automobile manufacturing and overhaul industry. With the continuous development of the domestic ...
