Embodiment 1

[0026] A preparation process for a spiral steel mesh rubber belt body. The prepared belt body has a width of 2800mm, a thickness of 25mm, and a length of 20mm. The skeleton material is a spiral steel mesh with a thickness of 6mm, and the covering rubber is EPDM rubber. EPDM.

[0027] The preparation process is as follows:

[0028] 1. Cover rubber calendering

[0029] Roll the upper cover rubber 2 and the lower cover rubber 3 so that the thickness of the upper and lower cover rubbers is 14-16mm;

[0030] Among them, the upper cover rubber and the lower cover rubber are mainly made of EPDM rubber mixed with other rubber materials;

[0031] 2. Spiral steel mesh calendering

[0032] The core rubber is respectively rolled on the upper and lower surfaces of the spiral steel mesh 1, and the thickness of the core rubber after rolling is 8mm;

[0033] The core rubber is formed by mixing natural rubber and neoprene;

[0034] 3. Forming

[0035] Lay the rolled spiral steel mesh wi...

Embodiment 2

[0042] The difference between this embodiment and Example 1 is that in order to further increase the width of the single-block spiral steel mesh rubber belt body, in Example 1, in order to further increase the width of the single-block spiral steel mesh rubber belt body, the step 3 ) during molding, a widening part 5 equal to the thickness of the spiral steel mesh is arranged on one side of the width direction of the spiral steel mesh. Set up a spiral steel mesh with core glue of equal thickness, and finally lay the upper covering glue. The width of the upper and lower covering glue = the width of the two spiral steel mesh + the width of the widening part + the width of the side glue; the widening part It is made of any one of rubber material, polyester cloth, and cotton canvas core.

[0043] After a lot of research time, it has been proved that the strength of the belt body prepared by using polyester or cotton canvas core as the skeleton layer can only reach 200-300N / mm, whi...

Abstract

The invention relates to a preparation technology for a spiral steel mesh rubber belt and belongs to the technical field of the preparation for the spiral steel mesh rubber belt. The preparation technology comprises the following steps: (1) rolling covering rubber; (2) rolling a spiral steel mesh; (3) molding; (4) vulcanizing; and (5) splicing. According to the preparation technology for the spiral steel mesh rubber belt provided by the invention, the production mode of preparing the rubber belt by using the spiral steel mesh instead of polyester or cotton canvas core is adopted, so that the whole strength of the rubber belt is greatly increased and the production process and the connecting mode are simplified; the cost is reduced by about 30% by preparing the product at same strength level in the production mode; the elongation of the product is small; the rubber belt is free from layering during use process; and the cost performance of the rubber belt is increased.

Description

technical field [0001] The invention relates to a preparation process of a spiral steel mesh rubber belt body, and belongs to the technical field of preparation technology of a spiral steel mesh rubber belt body. Background technique [0002] At present, the core materials of rubber belts produced at home and abroad are all polyester or cotton canvas. The single-layer core has low strength and cannot meet the strength requirements. Short life, long elongation, low cost performance. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings of the above-mentioned prior art, and provide a spiral steel mesh rubber belt body with high strength, low elongation, high cost performance and simple production process and its preparation process. [0004] A kind of preparation technology of spiral steel mesh rubber belt body of the present invention, its special feature is to comprise the following steps: [0005] 1. Cover rubber calenderi...
