Problems solved by technology

[0005] In addition, at present, most of the silk processing workshops use the method of soaking in the sizing agent pool and then removing and drying to carry out secondary modification. This process will not only cause a lot of water pollution and waste of water resources, but also produce a single variety of products. Performance indicators such as water content and oil content are not easy to control, which is time-consuming and labor-intensive

Embodiment 1

[0031] A method for producing thermoplastic chopped strands after modification of glass fiber filaments, comprising the steps of:

[0032] S1. The glass fiber filaments are chopped by a chopping system equipped with a guillotine, and the chopped length is 4mm to form short filaments;

[0033] S2. The chopped short filaments are transported to the granulator by the conveyor belt for granulation, and the sizing agent is atomized and sprayed through the high-pressure air gun in the granulator to form spare granules;

[0034] S3. The spare granules after spraying are transported to the vibrating fluidized bed by the conveyor belt for drying. The dust removal device is equipped above the vibrating fluidized bed. While drying, the dedusting device sucks the hairs mixed between the spare granules clean. That is, thermoplastic chopped strands modified by glass fiber filaments are obtained.

[0035] The chopping system includes a feeding platform, a guillotine blade and a blanking out...

Abstract

The invention relates to the technical field of production technology of thermoplastic chopped strands, in particular to a method for producing thermoplastic chopped strands after modification of glass fiber filaments. The process waste produced in the glass fiber production process of the present invention is short-cut by a Humen guillotine, granulated by a granulator, then sprayed with a self-developed infiltration agent, then dedusted by a dust removal device, and finally enters a vibration fluidization The bed is dried to produce thermoplastic-reinforced chopped strands. The sizing agent is composed of the following raw materials in weight percentage: coupling agent 0.3‑1%, film forming agent A1‑15%, film forming agent B1‑16%, lubricant 0.6‑2%, crosslinking agent 0.050.01‑0.3% , 0.05‑0.2% of antistatic agent and the balance of deionized water, and optimize the preparation method of wetting agent. The treatment process of the invention is simple and reasonable, and the final product is clean and of good quality.

Description

technical field [0001] The invention relates to the technical field of production technology of thermoplastic chopped strands, in particular to a method for producing thermoplastic chopped strands after modification of glass fiber filaments. Background technique [0002] Glass fiber is a new type of inorganic non-metallic material, which has a series of excellent properties such as high temperature resistance, corrosion resistance, low specific strength, good electrical insulation, low moisture absorption, and small elongation. Moreover, it has certain functional designability and is an irreplaceable basic material for the development of modern industry, agriculture, national defense and cutting-edge science. As a high-performance reinforced substrate, glass fiber is compounded with polymer materials to become various high-performance composite materials and FRP products. It is not only an indispensable material in the high-tech field and national defense industry, but also...
