Preparation method for silver drop-proof thermoplastic acrylic resin

Abstract

The invention discloses a preparation method of sliver-dropping proof thermoplastic acrylic resin, comprising 1. feeding an A material into a reaction kettle and uniformly stirring; 2. dripping B material, controlling the reaction temperature in the reaction kettle between 110 DEG C and 130 DEG C and controlling the time of dripping the B material between 3.5 to 4.5 hours; 3. after dripping, keeping the temperature between 110 DEG C and 130 DEG C for 5 hours; 4. adding C material, insulating and esterifying for 5 hours; 5. cooling to below 75 DEG C and filtering; then the sliver-dropping proof thermoplastic acrylic resin is obtained. The sliver-dropping proof thermoplastic acrylic resin of the invention has the advantages that the sliver-dropping proofing effect is realized without adding sliver-dropping proof accessory ingredient. The invention also solves the problems of lay separation and pig skin during resin storing and constructing process, paint film blackening and bad compatibility with other resins.

Description

technical field

[0001] The present invention relates to a kind of preparation method of acrylic resin, in particular, the present invention is a kind of preparation method of anti-silver thermoplastic acrylic resin. The characteristic of this acrylic resin is that the paint made of it and aluminum silver powder has anti-silver property on the ABS plastic base. Background technique

[0002] ABS plastics are widely used in home appliances, decoration, daily necessities and other fields at home and abroad. This type of plastic has the advantages of being cheap, light, durable, and recyclable, but it also has some disadvantages, such as unsightly appearance, poor scratch resistance, and easy discoloration for external use. In order to overcome these defects, the method of surface spray painting is generally adopted in the market to overcome the shortcomings of its appearance. The main technical requirements of the paint film on the surface of these household appliances are hig...
