Embodiment Construction

[0022] The first step of the present invention is to make slurry earlier, and the weight ratio of each composition of making 1844Kg slurry is as follows:

[0023] Paste resin: 960Kg Di-salt: 15Kg

[0024] Three salt: 20Kg Antimony trioxide: 100Kg

[0025] Zinc borate: 65Kg TCEP: 200Kg

[0026] DOP: 300Kg Paraffin: 180Kg

[0027] Carbon black: 4Kg

[0028] The second step is the making of adhesive, and the weight ratio of each composition of making 22Kg adhesive is as follows:

[0029] Resorcinol: 14Kg Urotropine: 8Kg.

[0030] Then, after the above-mentioned components are fully pulverized by a colloid mill, they are added to a beating tank, and then the binder is added in a ratio of 1%, and stirred at a high speed to make them evenly mixed.

Abstract

The invention relates to a manufacture method for PVC conveyor belt materials, which is technically characterized in that slurry is formed by mixing paste resin, disalt, threesalt, antimony trioxide, zinc borate, TCEP (also called phosphate tribasic (2-chloroethyl) ester), DOP (dioctyl phthalate), paraffin, carbon black according to a certain ratio; and an adhesive which is a mixture of resorcinol and urotropine with a certain ratio is added into a beating tank after being fully grinded by colloid, and is stirred by high speed to be uniformly mixed with the slurry. When the slurry is prepared, the adhesive is added according to the amount of 1 percent, and a belt body which is made by plasticization after the adhesive is added into the slurry ensures that gum and a core body are tightly combined, can not loose and is not easy to be torn, thereby the service life of the conveyor belt is prolonged by more than one time to obtain favorable effect.

Description

Technical field [0001] The invention relates to the technical field of producing PVC materials required for the production of conveyor belts, in particular to a method for producing PVC materials. Background technique [0002] At present, the plastic whole-core flame-retardant belts sold in the market are composed of internal skeleton and PVC material. Its skeleton material is generally a whole belt core woven by polyester fiber and cotton yarn, with a fluffy structure; the prepared slurry (PVC material) is fully impregnated into the weaving gap of the belt core and the inside of the fiber, and is plasticized at high temperature to form a whole . However, whether the slurry is firmly combined with the core fiber of the whole belt directly affects the quality of the product, and affects the operation and service life of the belt. Therefore, it is particularly important to find a way to combine the slurry with fiber reinforcement to improve the quality of the conveyor belt a...
