Problems solved by technology

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.

Embodiment Construction

[0031] The technical scheme that the present invention takes for realizing the above object is:

[0032] A kind of PC luggage manufacturing process, the process steps are:

[0033] (1) After 100% PC material is dehumidified and dried at 120°C for 4-10 hours, it is worth drying the PC material,

[0034] (2) After mixing the coloring material, first pass it through the mixer for 40 to 60 minutes, and then process it through high-temperature dehumidification and drying to obtain the coloring material;

[0035] (3) PC material in step 1, 3-10 parts of styrene-acrylamide copolymer, 0.5-1.5 parts of zirconium phosphate, 1-3 parts of hydrotalcite, 0.5-1.5 parts of boric acid Zinc and 1~3 parts of zirconium borate are thrown into the reaction kettle and stirred thoroughly, then 1~10 parts of the blending material in step 2 are added, and the PC raw material is obtained after fully stirred;

[0036] (4) Put the obtained PC raw material into the injection molding machine, the injectio...

Abstract

The invention belongs to the technical field of bag preparation and particularly relates to a PC bag manufacturing process. The characteristics of small density and high strength of a PC material are fully utilized. Compared with the prior art, the PC bag manufacturing process has the advantages that the weight of a bag is reduced by at least 20%, so that the bag is more convenient to carry; meanwhile, the strength can be guaranteed; the finally obtained PC bag which is integrally molded has the overall strength far higher than that of a bag formed by splicing plates; and the obtained PC bag has good high-temperature resistance and cold resistance, and has high hardness under the condition of low density, and normal use of the bag is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of luggage preparation, in particular to a PC luggage manufacturing process. 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-extinguishing, flame retardant, non-...
