[0088] Preparation method of high density polyvinyl chloride light conveyor belt

[0089] The second aspect of the present invention provides a kind of preparation method of high-density polyvinyl chloride light conveyor belt as described in the present invention, wherein, comprise the steps:

[0090] (1) Provide a high-density polyvinyl chloride resin composition;

[0091] (2) The high-density polyvinyl chloride resin composition is kneaded to obtain a kneaded material;

[0092] (3) After the kneaded material is plasticized, a plasticized material is obtained;

[0093] Wherein, the plasticizing process includes at least three heating stages between 140°C and 160°C and at least five stages of heat preservation between 160°C and 170°C;

[0094] (4) The plasticized material is calendered to obtain a calendered material;

[0095] Wherein, in the calendering process, at least five-stage roller calendering is adopted, including the first roller with a temperature of 160°C to 180...

Embodiment approach

[0125] The prior art uses paste-like polyvinyl chloride material, made by coating and scraping method, and is plasticized under normal pressure. This method forms products, which cannot reach high-density levels.

[0126] In the most preferred embodiment of the present invention, use extruder, calender, and reasonable formula, speed, temperature, and the light-duty conveyer belt that process makes to obtain high-density polyvinyl chloride light-duty conveyer belt.

[0127] The thickness of the high-density polyvinyl chloride light conveyor belt of the present invention is 1.6 to 9 mm, and the structure includes one cloth and one glue, two cloths and two glues, three cloths and three glues, and four cloths and four glues. The thickness and structure are set according to the requirements of different industries.

[0128] Beneficial effects of the present invention:

[0129] Existing light-duty conveyor belts are manufactured using traditional techniques, that is, using pasty po...

Embodiment 1

[0140] The present invention is applicable to the fields such as the building material industry, etc. that require high compression deformation resistance for light-duty conveyor belts, such as tile polishing systems. Arrange 43 polyester multifilaments with a specification of 1000D in the horizontal direction, and arrange 23 polyester monofilaments with a diameter of 0.3 mm in the weft direction. The warp and weft density of the base fabric is 43*23A28 / inch, that is, 43 radially arranged per square inch. It is 1000D polyester multifilament, 23 polyester monofilaments with a diameter of 0.3 mm are arranged in the weft direction, and 1 out of every 8 radial fibers with a diameter of 20D is evenly arranged in the 43 polyester fibers in the warp direction. carbon fiber.

[0141] A high-density light conveyor belt, the thickness of which is required to be 2 mm, a high-density light conveyor belt with two cloth and two rubber structures, including polyester ordinary fabrics, polyes...

Abstract

The invention provides a high-density polyvinyl chloride light conveying belt. The high-density polyvinyl chloride light conveying belt comprises a polyester fabric and a high-density polyvinyl chloride covering layer. The polyester fabric serves as a framework material. High-density polyvinyl chloride serves as a surface material and a filling material, and the high-density polyvinyl chloride light conveying belt with the corresponding thickness is obtained. The invention further provides a manufacturing method for the polyvinyl chloride light conveying belt. The high-density polyvinyl chloride light conveying belt obtained through the method has the beneficial effects that the interior is dense, the surface is flat, energy is saved, the tensile strength is high, and the surface is not prone to deformation and also has the beneficial effects that binding between the high-density polyvinyl chloride light conveying belt and the polyester framework material is firm, and the peeling strength is high. The using performance of the conveying belt can be obviously improved, and the service life of the conveying belt can be obviously prolonged; and the work condition of a conveyor can be better improved, the replacing period is prolonged, and the using cost is reduced.

Description

technical field [0001] The invention belongs to the field of light conveyor belt and its preparation, in particular to a high-density light conveyor belt and its preparation method. Background technique [0002] Light conveyor belts are widely used in the field of building materials industry. As an uninterrupted load transfer carrier, in the face of various working environments, high pressure, high humidity, high dust and other environments, light conveyor belts are required to be moisture-resistant, temperature-resistant, wear-resistant, and compression-resistant. Deformation etc. [0003] Existing light-duty conveyor belts are manufactured using traditional techniques, that is, using pasty polyvinyl chloride materials, and manufacturing them through processes such as pulping, slurry coating and scraping, and oven plasticization. During the plasticization process of the polyvinyl chloride material in the oven, the material density is poor due to the surface slurry coating ...
