Abstract

The invention discloses an internal plasticization artware molding emulsion which comprises the following solid components: vinyl acetate, polyving akohol, butyl acrylate, crylic acid, an internal plasticizer, potassium peroxodisulfate, an anion-nonionic emulsifier, biological preservatives and an organic silicon defoamer. A preparation method of the molding emulsion comprises the following steps of: preparing protective colloid, preparing a pre-emulsification solution, carrying out seeding polymerization, carrying out continuous polymerization, and gelatinizing to obtain the internal plasticization artware molding emulsion. The invention has the beneficial effects that after an internal plasticization method is adopted, and the copolymerization proportion of the vinyl acetate and the butyl acrylate are adjusted, the adhesive film of the molding emulsion is proper in flexibility, can not be adhered to a film plate, free from cracks when being formed, free from springback after being impressed, free from the precipitation of plasticizer, environmentally-friendly, and non-toxic; and a finished product is distinct in grain, obvious in embossing effect, and free from flaw in the body.

Description

technical field [0001] The invention relates to a handicraft plastic emulsion, in particular to an internally plasticized handicraft plastic emulsion and its preparation method and application. Background technique [0002] Handicraft molding emulsion refers to a molding emulsion that coats a layer of clay on the surface of handicrafts, and then embosses patterns through molds, so that the patterns on the surface of handicrafts have a relief effect. Such as photo frames, picture frames, door frames, furniture, etc. are processed by this process, and the appearance is more beautiful and the shape is more realistic. At present, this handicraft with relief effect is widely recognized by consumers and exported to Europe, America, the Middle East and other regions, earning a large amount of foreign exchange every year. [0003] The surface of traditional handicrafts is stamped and fixed on the surface of the substrate with iron sheets or plastics. It is difficult to form an orga...
