Description

A kind of high-strength polyethylene light-type conveyer belt and preparation method thereof
Technical field
The present invention relates to a kind of tobacco business conveyer belt, more particularly to a kind of high-strength polyethylene light-type conveyer belt and its Manufacture method.
Background technology
Polyethylene conveying belt is as a kind of light-type conveyer belt, with its tensile strength height, good, frivolous circumnutating property, oil resistant, nontoxic Hygienic, easy to clean the features such as, it is widely used in the industries such as food processing, tobacco.
It by polyethylene is coat that polyethylene conveying belt, which is, using polyester chemical ＆ blended fabric as framework material, main conveying is light, in One class conveyer belt of quality material.Polyethylene has acid and alkali-resistance, corrosion-resistant, nontoxic in the case of 800 DEG C of high-temp combustions, and accords with U.S. FDA food grade hygienic is closed, therefore polyethylene conveying belt is a kind of novel environment friendly conveyer belt, is had well following Development prospect.
The processing mode of current polyethylene conveying belt mainly has two kinds of cladding process and the tape casting, and which kind of ineffective mode adds Work, framework material uses polyester staple fibers dimensional fabric.Because polyester staple fiber is through cut-out in spinning post-processing by tow Into all size shorter yarn, there is filoplume on surface, plentiful fluffy, be very beneficial for improve and non-polar material polyethylene between Adhesive property.But polyester staple fiber self-strength causes polyethylene conveying belt extension by force intensity and broken strong than relatively low Degree does not all reach requirement, it is impossible to meet long distance delivery and higher level client's use demand.
The content of the invention
In order to solve the above problems, present invention aims at provide a kind of high-strength polyethylene light-type conveyer belt and its manufacture Method.
The purpose of the present invention can be achieved through the following technical solutions：
The manufacture method for the high-strength polyethylene light-type conveyer belt that the present invention is provided, methods described comprises the following steps：
S1：High-strength composite yarn woven fabric is shaped；The warp-wise of the high-strength composite yarn woven fabric is using RING SPINNING covering yarn Spinning system is by PFY and polyester staple fiber composite spinning, and PFY line density is that 800D low shrinkage polyesters activate silk, Polyester staple fiber uses the short yarns of 10S/3, and broadwise uses the short yarns of 21S/6, and fabric warp-wise density is 35~40/inch, fabric latitude It is 15~20/inch to density, weave uses plain weave structure；The radial direction yarn of this fabric uses the spinning of RING SPINNING covering yarn Mode feeds long filament PFY and chopped fiber composite spinning at the front roller nip of ring spinner together with chopped fiber Enter, long filament is placed in the middle of chopped fiber, the purpose for the arrangement is that allow chopped fiber preferably to envelope long filament, and long filament is closely assembled Together, that is, covering yarn is formed.This spinning system is that can make full use of PFY itself high-strength characteristic, and is not influenceed Adhesive property between peripheral chopped fiber and polyethylene, and make full use of the low noise characteristic of chopped fiber.
S2：Polyethylene powders primary coat is used on high-strength composite yarn woven fabric after step S1 sizings, and at 160~180 DEG C Lower carry out thermal finalization, is flattened through hot-pressing roller, constitutes priming coat；
S3：High-strength polyethylene film is extruded using casting technique on step S2 priming coat, makes polyethylene and priming coat It is combined, high-strength polyethylene light-type conveyer belt is produced after constituting polyethylene facestock, cooling room temperature.
In step s 2, the polyethylene powders are high melting means polyethylene powders, are adjusted with polythene material and melting means Agent blending granulation, its weight ratio is 100：4-8, then crushes obtained under liquid nitrogen cryogenics environment.The high melting means polyethylene The shore hardness of powder primary coat is 90A.During conveyer belt primary coat, this high melting means polyethylene powder will be poly- by high-temperature heating Ethylene powder melts, and the high fluidity after it is melted is permeated to fabric, polyester staple fibers peacekeeping long filament is combined closely Together, so as to reach the purpose for improving conveyer belt bulk strength.When melting means conditioning agent ratio is too high, fabric, high intensity can be made Polyethylene film and the compatibility of primary coat are bad, easily cracking so that obtained high-strength polyethylene light-type conveyer belt intensity decreases. If melting means conditioning agent ratio is too low, melting means conditioning agent does not just serve.
It is preferred that, the polythene material and melting means conditioning agent weight ratio are 100：4.5-5.5.Under this ratio, at this The compatibility of fabric, high-strength polyethylene film and primary coat under individual system is best, the high-strength polyethylene light-type conveyer belt of system Physical property is best.
In step s 2, the temperature of the hot-pressing roller is at 120~150 DEG C, and pressure is 1~2MPa.
In step s3, the thickness of the extrusion high-strength polyethylene film is 0.3mm, and film temperature is at 200~220 DEG C, heat Shaping time is in 1~2min.
High-strength polyethylene light-type conveyer belt prepared by above-mentioned manufacture method.
Application of the above-mentioned high-strength polyethylene light-type conveyer belt in tobacco business.
The present invention compared with prior art, with advantages below and effect：
1st, the PFY and short fiber material that high-strength composite yarn woven fabric of the present invention is radially used easily are obtained, only by spy Different spinning process can be prepared by, and fabric cost rises smaller.
2nd, the present invention uses high-strength composite yarn woven fabric, and PFY and chopped fiber are two relatively independent entirety, short Fibre compact envelopes long filament, makes full use of the high intensity of long filament and the low noise characteristic of chopped fiber,
3rd, the present invention is PE modified by high rigidity using addition melting means conditioning agent, greatly improves its mobile performance, passes through Heating pressurization enables polyethylene fully to penetrate into fabric, can be tight by two independent entirety of PFY and chopped fiber It is close to be combined together, so as to improve the bulk strength of polyethylene conveying belt.
4th, using the manufacture method of the present invention, 1% extension stress strength ratio routine techniques improves more than 50%, is conducive to preventing Only conveyer belt is elongated in use, reduces the tensioning length requirement of conveyer.
