Production method of continuous glass fabric reinforced thermoplastic sheet

Abstract

The invention discloses a continuous glass fabric reinforced thermoplastic sheet, which uses a packaged continuous glass fabric as an initial material and thermoplastic plastic as a base stock. The production method comprises the following steps of unreeling, flattening, plastic dipping, finishing, thermosetting, molding processing and reeling, wherein the seven steps are continuously produced on a production line. The production method is reasonable and ensures high production efficiency and high finished product quality.

Description

Technical field [0001] The invention relates to a production method of a continuous glass fiber cloth reinforced thermoplastic plastic sheet, belonging to the technical field of materials. Background technique [0002] The continuous glass fiber cloth reinforced thermoplastic plastic sheet of the present invention generally has a thickness of less than 1 mm, and is a sustainable thin synthetic material. [0003] The reinforced plastic sheet can be directly used for the surface decoration of solid parts, or it can be laminated and bonded to form a composite board, which is used to manufacture panels for solid parts such as floors, furniture and indoor partitions. Wait. Therefore, the reinforced plastic sheet is widely used in various fields. [0004] At present, most of the existing technologies use glass fibers or glass fiber bundles as the memory reinforcement material of the plastic matrix, and produce the reinforced plastic sheet or other products through various methods. The e...

Problems solved by technology

The production method of this reinforced plastic product, because the reinforcing material it adopts is a fiber bundle, not a continuous fiber bundle, let alone a fabric, so the tensile strength of the finished product, especially the transverse tensile strength, is obviously unsatisfactory. , not enough to produce high-strength plastic products

[0008] And the Chinese patent application number is 200710025869.1, after pulverizing and granulating the pure glass fiber polypropylene waste material, blending and granulating with polyethylene plastics, etc., and then producing reinforced plastic products such as plates, although this patent application provides waste recycling technology, but the mechanical properties of its finished products are obviously ignored, and it is not enough to produce high-strength plastic products
