Description

Anti-adhesion polyethylene light conveying belt and preparation method thereof
Technical Field
The invention relates to the technical field of conveying belts, in particular to an anti-adhesion polyethylene light conveying belt and a preparation method thereof.
Background
The light conveyer belt is a fine product in the conveyer belt, takes fabrics of cotton, Polyamide (PA), terylene and the like as a belt core or a framework material, takes rubber (including rubber and plastic) or plastics as a covering layer (or has no covering layer belt), and has smooth surface and deep and shallow patterns or transverse section bars, baffles and corrugated flanges with various patterns. The light conveyer belt has the characteristics of light and thin belt body, good dimensional stability, high precision, bright color, high tension, safety, no toxicity and the like. Meanwhile, with the development of preparation technology, the product types and performance range which can be selected by users are wider and wider, and the product has various special performances such as static resistance, corrosion resistance, flame retardance, low noise and the like.
According to the national standard GB/T236772009 of lightweight conveyor belts, they can be divided into two main categories according to the type of material of the covering layer of the lightweight conveyor belt: rubber type (including rubber-plastic type) and plastic type (including polyvinyl chloride PVC, thermoplastic polyurethane elastomer TPU, polyethylene PE, etc.). Conventional rubber conveyor belts, invented by dupont in the united states and used for the conveyance of various articles, have been used for over 100 years. Basically, natural rubber, nitrile rubber, chloroprene rubber, styrene-butadiene rubber and the like are used as main components. At present, the use of modified raw materials such as plastic reinforced rubber, rubber toughened plastic and the like prompts the conveying belt taking rubber as a main raw material to turn to a novel rubber-plastic composite conveying belt.
The development of the high polymer material modification technology has a great promoting effect on the development of new materials for the conveyor belt, and the novel conveyor belt material with high strength, high cohesiveness, high friction, flame retardance, antistatic property, environmental friendliness and other additional properties can be obtained by modifying the high polymer material.
The conveyer belt is generally used for transporting bulk materials, and a conveyer belt with special properties is needed to finish conveying on special working conditions, for example, an anti-adhesion conveyer belt is needed to finish conveying biscuits, candies and cakes in food processing.
Disclosure of Invention
Aiming at the defects in the prior art, the invention provides an anti-adhesion polyethylene light conveyor belt and a preparation method thereof, and aims to solve the technical problem of realizing the purpose of anti-adhesion on the surface of the conveyor belt in the food processing process.
In order to solve the technical problems, the technical scheme provided by the invention is as follows: the anti-adhesion polyethylene light conveyor belt sequentially comprises a polyolefin colloidal layer, a bottom fabric layer and a cotton fiber fabric framework from top to bottom, wherein the polyolefin colloidal layer comprises 100 parts by weight of polyethylene powder, 5 parts by weight of lubricant and 3 parts by weight of anti-adhesion agent, and the cotton fiber fabric framework and the bottom fabric layer are woven by cotton fibers.
Further, the bottom fabric layer comprises warp and weft, the warp comprises first warp and second warp, the first warp is made of single polyester fiber, the second warp is made of multiple cotton fibers, and the first warp and the second warp are arranged at intervals.
Further, the polyolefin is model number mitsui chemical DF 810.
Further, low molecular weight polypropylene with an irregular structure is selected as a lubricant of PE.
Further, the anti-blocking agent is a water gloss chemical SILTON JC-50 anti-blocking agent.
Further, the preparation method of the conveyer belt comprises the following steps:
selecting 100 parts of PE powder, 5 parts of lubricant and 3 parts of anti-blocking agent according to the parts by weight, fully and uniformly mixing the PE powder, the lubricant and the anti-blocking agent, then coating the mixture on a polyester fabric framework, wherein the coating thickness is 0.4-0.5mm, and then plasticizing at the high temperature of 180-200 ℃ for 0.15h to obtain the polyolefin substrate anti-blocking light conveyor belt.
The beneficial effect that this technical scheme brought is:
1. the three-well chemical DF810 polyethylene resin and the water-luster chemical SILJC-50 anti-adhesion agent are used in a blending and matching mode, so that the adhesion of food and the surface of a conveying belt during food conveying can be effectively prevented, and meanwhile, compared with a common polyolefin glue layer conveying belt, the three-well chemical DF810 polyethylene resin has lower deformation rate and is more suitable for food conveying.
2. The low molecular weight polypropylene with an irregular structure is used as a lubricant of PE, the performance is excellent, and the dispersibility of other additives can be improved.
3. The anti-blocking agent is a gloss chemical SILTON JC-50 anti-blocking agent which can form fine concave-convex on the surface of the film, so that the contact area between the films is reduced, Janie is prevented, the anti-blocking performance is improved, and meanwhile, the anti-blocking agent also has high safety performance.
4. The second warp that many fibre constitute can form outstanding strip structure to form the strengthening rib, and then make the tensile strength of whole conveyer belt obtain improving.
5. The tensile strength of the conveyor belt can be improved by adopting the cotton fiber plant skeleton woven by cotton fibers and the bottom fabric layer.
6. The preparation process is environment-friendly, and the oil-resistant and anti-adhesion purposes in the food processing process are achieved through the oil-resistant and anti-adhesion characteristics of the polyolefin colloidal layer on the surface of the conveying belt.
