Embodiment Construction

[0021] The present invention is further described below in conjunction with specific examples.

[0022] Formulation raw materials / product performance

[0023] It can be seen from the above table that the high-friction conveyor belt material obtained by blending and modifying ordinary PVC resin with nitrile rubber and XNBR liquid rubber plasticizer has achieved the effect of [East Kochi Takeshi. "Plastic" (ブラスチツクスユ一 ツ), 1985, 31(5): 101] reported the superior performance of the copolymerized PVC-TPE resin produced by international large companies. That is to say, under the same hardness, although its tensile strength is not as good as that of thermoplastic polyurethane, it is higher than other thermoplastic elastomers; the compression set and heat deformation rate are lower than soft PVC, which are close to rubber, and the resilience is improved; heat and cold resistance Superior to soft PVC, good shape retention at high temperature, and less dependence of hardness on ...

Abstract

The invention relates to a high frictional conveyer apron material, which comprises basis materials, elastomer, elasticizer, stabilizer and reinforcing fillers. The said basis materials are made of PVC paste resin and PVC blending resin, the said elasticizer includes XNBR rubber elasticizer. In the invention, using acrylonitrile butadiene and XNRB liquid rubber elasticizer to get the high frictional conveyer apron material by blend modifying the common PVC resin. The said high frictional conveyer apron material can be used in a plastic canvas collosol applying process art, and its tensile strength above other thermoplastic elastomers except thermoplastic polyurethane in the same stiffness, its compressive permanent deformation and rate of thermal deformation are less than soft PVC and near rubber, the rebound elasticity increases, the heat and cold endurance are more than soft PVC, the form retentivity is good in high temperature, the dependence between stiffness to temperature is less than soft PVC, the flexural fatigue is more than common soft PVC.

Description

technical field [0001] The invention relates to a conveyor belt material, in particular to a high-friction conveyor belt material. Background technique [0002] The high-friction conveyor belt is one of the conveyor belts used in the automatic sorting conveyor line of postal letters and the automatic scanning and identification of the barcode of small commodity packaging in the food, tobacco and other industries. Because the conveyor belt runs very fast, some are faster than 50 meters / Minutes, and some conveyor lines are transported with a high and low slope of 15° to 45°. The scanning and resolution sensors require that the very small and light items carried on the conveyor line have good stability and cannot shake. The operating conditions of the high friction conveyor belt require the elastic modulus of the high friction conveyor belt material to be as large as possible, but at the same time require the material to have good wear resistance. The original domestic rubbe...
