Embodiment Construction

[0025] Preferred embodiments of the present invention are described below, and it should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0026] A non-shrinkage treatment method for soft glass, comprising the following steps:

[0027] 1) The PVC raw material is passed through a metering device, a high-speed stirring device, a cooling and stirring device, an internal mixer, and a calendering device to obtain a calendered film. According to the weight ratio, the raw material is composed of: 100 parts of PVC rubber, 2.5 parts of epoxy soybean oil, 46 parts of plasticizer, 3 parts of stabilizer, 23.5 parts of processing aids, including 0.8 parts of nano-gold, 0.6 parts of nano-cobalt, 0.6 parts of nano-iron, 2.5 parts of graphite powder, 1.5 parts of glass fiber powder, and 3 parts of mica powder , 2.5 parts of fruit acid, 3 parts of glacial acetic acid,...

Abstract

The invention provides a non-shrinkage treatment method of soft glass. The method comprises the following steps: (1) preparing PVC raw materials, including 100 parts of PVC glue, 2-3 parts of epoxidized soybean oil, 40-50 parts of plasticizer, 1-5 parts of stabilizer, 1-25 parts of processing additives which include 0.5-1 part of nano-gold, 0.5-1 part of nano-cobalt and 0.5-1 part of nano-iron, inparts by weight, through a metering device, a high-speed stirring device, a cooling stirring device, an internal mixer and a calendaring device; (2) preheating the film; (3) annealing the film with an oven; (4) immersing in cooling water; (5) drying the film; (6) performing air cooling at normal temperature; (7) cooling through cooling rollers which are filled with cooling water; and (8) rolling.Non-shrinkage of soft glass can be realized by the design of process and formula through preheating, annealing, cooling, drying, cooling and other processes.

Description

technical field [0001] The invention belongs to the technical field of PVC, in particular relates to a kind of soft glass, and more specifically relates to a non-shrinkage treatment method for soft glass. Background technique [0002] Polyvinyl chloride is referred to as PVC in English, and soft glass is also known as PVC soft crystal board. It is a high-quality plastic composite material. It has the characteristics of smooth surface, bright and transparent, no cracks, no bubbles, and uniform color. It is currently mainly used in electronics. , chemical, pharmaceutical, working platforms, etc., soft glass has no toxicity, and it has good flame retardant properties. [0003] Soft glass tends to shrink and wrinkle during cutting and use, causing the edge of soft glass to warp easily, affecting the appearance, and shrinking during cutting, resulting in shortened size. Contents of the invention [0004] The present invention overcomes the shortcomings in the prior art and pro...
