Epoxy modified lacquer putty

Abstract

An epoxy modified puddy for metallic materials is composed of components A and B. Said component A is prepared from epoxy modified unsaturated polyester resin, functional filler, quinone substance, cobalt naphthenate (or isooctoate), polyvinyl chloride or SiO2 gas, and active diluent. Said component B is vinylamide polymer. Its advantages are long application time (60 min) and high low-temp high-moisture performance.

Description

technical field

[0001] The invention relates to a primer coating material in large-area embedded filling materials on metal surfaces required by trains, automobiles, machine tools, shipbuilding and motor manufacturing industries, in particular to an epoxy-modified unsaturated putty. Background technique

[0002] In the background technology, commonly used putties include alkyd putty, epoxy putty and putty putty, among which the putty with unsaturated polyester resin as the main raw material has good overall performance. Chinese patent application 94115901 discloses a formula of "quick-drying high-grade polymerized putty at normal temperature" and its production method. It discloses the formula of A component and B component, and the formula (weight ratio) of its A component is: 100 parts of saturated resin, 80-90 parts of talcum powder, 5-10 parts of paris plaster powder, 5-10 parts of heavy calcium carbonate, 5-10 parts of light calcium carbonate, 15-25 parts of quartz sand...
