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 thermoplastic chopped yarn production processes, and in particular, relates to an impregnating compound for thermoplastic chopped yarn production, a preparation method of the impregnating compound and a method for producing the thermoplastic chopped yarn after modification of the glass fiber filaments. Process waste generated in the glass fiber production process is chopped by a tiger's guillotine, granulated by a granulator, sprayed with the independently developed impregnating compound, dedusted by a dedusting device, finally enters a vibrated fluidized bed and is dried to finally produce the reinforced thermoplastic chopped yarn. The impregnating compound is prepared from the following raw materials in percentage by weight: 0.3-1% of a coupling agent, 1-15% of a film-forming agent A, 1-16% of a film-forming agent B, 0.6-2% of a lubricating agent, 0.05-0.3% of a cross-linking agent, 0.05-0.2% of an antistatic agent and the balance being deionized water. The preparation method of the impregnating compound is optimized. The treatment process is simple and reasonable, and the final product is clean and good in quality.

Description

technical field [0001] The invention relates to the technical field of thermoplastic chopped yarn production technology, in particular to a sizing agent for thermoplastic chopped yarn production and a preparation method thereof, and a method for producing thermoplastic chopped yarn 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...
