Embodiment Construction

[0025] The present invention will be described in detail below in conjunction with the examples. The weight parts and weight percentages of the raw materials used to prepare the substrate and the plastic sheet in the specific examples are shown in Table 1 and Table 2.

[0026] 1. Substrate preparation:

[0027] The first step: weigh the raw materials according to the formula in Table 1;

[0028] The second step: put 1 # Put the smoked sheet rubber into the rubber mixer for two-stage plastication, and then put in Z-mercaptobenzothiazole, dithiodibenzothiazole, N-phenyl-α-naphthylamine, N-phenyl —β-naphthylamine, zinc oxide, stearic acid, paraffin, and then put in one-half of carbon black, pottery clay, and light calcium carbonate;

[0029] The third step: put 1 / 2 of the pine tar and 1 / 2 of the remaining carbon black, pottery clay, and light calcium carbonate into the material when the above process is completed, and then put 1 / 2 of the remaining pine tar into Mix well.

Abstract

The invention relates to a material for manufacturing a composite water seal and a preparation method thereof. The material is compounded by a base material and a plastic sheet, wherein the base material is prepared from 1 smoke sheet rubber, sulfur, Z-thiol benzothiazole, dithio-bisbenzothiazole, carbon soot, pottery clay, light calcium carbonate, N-phenyl-alpha-naphthylamine, N-phenyl-beta-naphthylamine, zinc oxide, stearic acid, paraffin and pine tar; and the plastic sheet is prepared from 1 smoke sheet rubber, high styrene rubber, vinyl chloride-acetate copolymer, carbon soot, white carbon black, sulfur, TMTD dithio-tetramethyl thiuram, CZN-cyclohexyl-2-benzothiazole sulfonamide, DM dithio-bisbenzothiazole, zinc oxide, stearic acid, dibutyl phthalate, zinc stearate, barium stearate, N-isopropyl-N-diphenyl-para-phenylene diamine and N-phenyl-alpha-naphthylamine. The frictional coefficient is low, and the product can be bent randomly; the problems of special packing expense and high transportation expense for the water seal are solved, the production process is concise, and the manufactured water seal has higher rate of certified products than other water seals and better economical efficiency.

Description

technical field [0001] The invention relates to a rubber seal for a water conservancy gate, in particular to a preparation material and a preparation method of a composite water seal. Background technique [0002] The new low-friction composite water seal products are widely used in the water-stop devices of various gates in large and medium-sized water conservancy, hydropower, ships, ports, chemical industry, petroleum, metallurgy, machinery and municipal engineering construction, especially suitable for large-diameter, high-head deep holes Water-stop devices for plane gates and arc gates, etc. [0003] Existing water seals are mainly pure rubber water seals and polytetrafluoroethylene composite water seals. [0004] Due to the various reasons of the nature of the rubber material, although the pure rubber water seal has good sealing performance in its application, it is convenient for transportation and operation, but its friction coefficient is high and it is easy to wear...
