Problems solved by technology

[0004] However, in all technologies, PC bags are first molded into sheets by injection molding, and then assembled to form a whole bag through the sheets, and there is no information and documents on PC bags that are directly integrally formed.
The reason is that if it is integrally formed, the requirements for the PC material are higher, and there are many bending parts and corners of the whole bag, and it is difficult to form the whole bag with the integrally formed PC material.

Abstract

The invention discloses a preparation technology for an integrally molded PC (polycarbonate) case. The preparation technology comprises the following steps: step 1, a PC material is dried, and the dried PC material is prepared; step 2, a pigment is well prepared through blending: materials are mixed sufficiently and dried, and the prepared pigment is obtained; step 3, 1,000-2,000 parts by weight of the PC material in the step 1, 3-10 parts by weight of a styrene / acrylamide copolymer, 0.5-1.5 parts by weight of zirconium phosphate, 1-3 parts by weight of hydrotalcite, 0.5-1.5 parts by weight of zinc borate and 1-3 parts by weight of zirconium borate are stirred sufficiently and added with 1-10 parts of the prepared pigment in the step 2, the materials are stirred sufficiently, and a PC raw material is obtained; step 4, the PC raw material obtained in the step 3 is injected into a mold by a high-speed injection molding machine for direct injection molding of a case body; step 5, the case body obtained in the step 4 is covered with a PE (polyethylene) protective film; step 6, the case body obtained in the step 5 is dehumidified and packaged. Due to integral molding, the obtained PC case has better high-temperature resistance and cold resistance and still has better hardness under the condition of low density, and normal use of the case is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of case and bag preparation, more specifically, it relates to a preparation process of a once-formed PC case. Background technique [0002] As the main equipment for travel, luggage plays an extremely important role in the journey, and providing excellent protection for luggage is the first priority. Therefore, it is required not only to have accommodation, but also to have functions such as anti-extrusion, waterproof, and anti-collision. Especially the luggage should accommodate luggage, so reducing the weight of the luggage itself to the greatest extent is also what people are pursuing. Among them, polycarbonate (PC), a material from the aviation industry, is as light as a swallow but as hard as steel. Amorphous thermoplastic resin with excellent electrical insulation, elongation, dimensional stability and chemical corrosion resistance, high strength, heat resistance and cold resistance; also has self-ext...
