Description
Technical field
The present invention relates to a kind of manufacture field of composite, especially a kind of manufacture method of thermoplastic resin Nomex and production line.
Background technology
Glass fiber mat reinforced thermoplastic composite (GMT) is is matrix with thermoplastic resin, take glass mat as the sheet structure material strengthening skeleton.Having good toughness, intensity is high, density is little, excellent corrosion resistance and heat resistance, good mouldability, waste material reproducible utilization can the advantage such as long-term storage, is the green material of low energy consumption, non-environmental-pollution.
Chopped Strand Mat in current GMT sheet material is processed and the precursor felt made with needle point method through polypropylene sizing agent special, coupling agent etc. by E glass fibre, and the Nomex that domestic supply thermoplastic resin strengthens is still immature.
Thermoplasticity Woven glass cloth is not had as base cloth in existing thermoplastic resin Nomex structure, pure in acupuncture after the combing of thermoplasticity short glass fiber.There is intensity low, the shortcomings such as mutability.
The thermoplastic resin Nomex product of our company with different types of thermoplasticity Woven glass cloth for base cloth, the thermoplasticity chopped glass fiber fiber of certain mass is sprinkled in the one side of thermoplasticity Woven glass cloth, by the needling action up and down of pricker, thermoplasticity Woven glass cloth and thermoplasticity short glass fiber are combined into an entirety.
Thermoplasticity Woven glass cloth used in product, its grammes per square metre scope is 100 ~ 1000 grams/m, and kind comprises thermoplasticity glass woven roving, thermoplasticity glass stitch bonded fabrics etc., is applicable to the client of various uses.Wherein thermoplasticity glass woven roving and thermoplasticity glass stitch bonded fabrics thermoplasticity glass used, be the non-twist direct yarn through the process of polypropylene sizing agent special, number number is generally 1200tex and 2400tex.
Thermoplasticity short glass fiber used in product, its grammes per square metre scope is 50-500 gram/m, can select eight beam splitting, very bundle, 16 beam splitting.This thermoplasticity short glass fiber, be formed with short the cutting of folded yarn by non-twist short the cutting through the process of polypropylene sizing agent special, single number is as follows: eight beam splitting, 33tex; Extremely restraint, 26tex; 16 beam splitting, 16.5tex.
Summary of the invention
The object of the invention is the deficiency in order to solve above-mentioned technology and manufacture method and the production line of thermoplastic resin Nomex are provided, with thermoplasticity Woven glass cloth for base cloth, by a kind of novel thermoplastic resin Nomex that thermoplasticity short glass fiber and thermoplasticity Woven glass cloth are combined with each other and make by the mode of acupuncture, it has the advantages such as vertical transverse strength is high, not yielding, porosity is high, thermoplastic resin melt impregnation is quick.
In order to achieve the above object, the manufacture method of a kind of thermoplastic resin Nomex designed by the present invention, comprises the following steps:

Chopped device is made up of rotor, roller, mace, and rotor is mounted with blade, and thermoplasticity short glass fiber, after short cutting, through evenly the breaing up of mace of rotating, falls within the upper surface of the thermoplasticity Woven glass cloth on the uncoil-stand of below;
The thermoplasticity Woven glass cloth being covered with thermoplasticity short glass fiber enters needling device through conveyer belt, and this needling device is made up of upper needle plate, lower needle-bar and drive disk assembly; The thermoplasticity Woven glass cloth being covered with thermoplasticity short glass fiber in needling device by needle plate with the speed acupuncture of 1 time/second, there is hangnail at the syringe needle place of pricker, at pricker stroke to bottom and when returning, short for part thermoplastic yarn cutting retracts by hangnail; Through a series of acupuncture operation, thermoplasticity short glass fiber is evenly distributed in the upper and lower surface of thermoplasticity Woven glass cloth, and in puffy, both closely combine by mechanical force and obtain thermoplasticity acupuncture composite felt;
After thermoplasticity acupuncture composite felt is made, then through trimming device, wrap-up and become finished product.
The present invention also provides a kind of thermoplastic resin needle felt production line, comprise uncoil-stand, creel, chopped device, conveyer belt, needling device, trimming device and wrap-up, the rear of uncoil-stand is located at by described creel, described creel is provided with thread tube and thermoplasticity short glass fiber is delivered to chopped device above uncoil-stand by thread tube, described chopped device is by rotor, roller, mace forms, rotor is mounted with blade, thermoplasticity short glass fiber is after short cutting, through evenly breaing up of mace rotation, fall within the upper surface of the thermoplasticity Woven glass cloth on the uncoil-stand of below, the thermoplasticity woven roving being covered with the short yarn cutting of thermoplasticity enters needling device successively through conveyer belt, trimming device, wrap-up.
As preferably, described needling device is made up of upper needle plate, lower needle-bar and drive disk assembly.
Further, the adjacent two panels blade space on the deflector roll in described chopped device is 50mm.
The thermoplastic resin Nomex that manufacture method of the present invention obtains, with thermoplasticity Woven glass cloth for base cloth, by the mode of acupuncture, the thermoplastic resin Nomex that thermoplasticity short glass fiber and thermoplasticity Woven glass cloth are combined with each other and make had the advantages such as vertical transverse strength is high, not yielding, porosity is high, thermoplastic resin melt impregnation is quick.
Thermoplastic resin needle felt production line of the present invention has flow scheme design compact and reasonable, easy to operate, can produce in a large number, and step connects closely, the thermoplastic resin Nomex made has the advantages such as vertical transverse strength is high, not yielding, porosity is high, thermoplastic resin melt impregnation is quick.
