Embodiment 1

[0029] The injection molding method of rubber and plastic electrical insulation hand gloves and rubber boots uses rubber and plastic as the main raw material and adopts a movable plunger rubber injection machine with a pre-plastic screw. The injection holes of the mold are connected, and the processing steps are as follows:

[0030] 1. Rubber as the main raw material: In order to meet the different performance requirements of gloves and rubber boots, rubber is used as the main raw material, and a small amount of plastic can be added. Natural rubber, synthetic rubber, or synthetic rubber, natural rubber and plastic may be used alone.

[0031] Raw materials: natural rubber 100Kg, zinc oxide 5 Kg, stearic acid 3 Kg, sulfur 0.6 Kg, accelerator M0.5 Kg, accelerator D0.4 Kg, accelerator DM0.5 Kg, antioxidant RD1 Kg, hydraulic oil 10 Kg, active nano ultrafine calcium 20 Kg.

[0032] 2. Mastication: The rubber is thinly passed in the open mill for 6-8 times, and the roller temperatu...

Abstract

The invention relates to an injection moulding method of rubber and plastic electric insulation hand gloves and rubber boots, belonging to the technical filed of rubber and plastic moulding. The injection moulding method of the rubber and plastic electric insulation hand gloves and the rubber boots comprises the following steps: (1) taking rubber as a raw material; (2) plastication: thinly passing 3-15 times when the roller space on an open mill is 1-2mm; (3) mixing: mixing in the open mill or a banbury mixer; (4) filtering by a filter; (5) shaping to prepare rubber sheets the thickness of which is 10-30mm and the width is 40-200mm; (6) plasticizing: adding the rubber sheets to a plunger type rubber injection machine provided with a pre-plasticized screw rod to plasticize; (7) injection and sulfuration: connecting the nozzle of a movable plunger type rubber injection moulding machine provided with the performing screw rod with the injection hole of the mould locked in a flat-plate pressure vulcanizer, injecting size into a hand glove mould or a rubber boot mould for moulding, maintaining pressure and vulcanizing; and (8) demoulding products. The method of the invention has the advantages of simple process, accurate control, small equipment investment, low cost, high production efficiency, high product density, good comprehensive performance, high electric insulation degree and the like.

Description

technical field [0001] The invention belongs to the technical field of rubber and plastic molding, and in particular relates to an injection molding method of rubber and plastic electrically insulating hand gloves and rubber boots. Background technique [0002] At present, the production of high-voltage (AC voltage: 30-40KV) rubber-plastic electrical insulating hand gloves and rubber-plastic electrical insulating rubber boots is limited to the use of special rubber injection molding machines for hand gloves or special rubber injection molding machines for rubber boots. This kind of special equipment has complex structure, large equipment investment, and can not pre-plasticize the rubber material before injection molding. Its processing technology is complicated, the control is inaccurate, the production efficiency is low, the production cost is high, the degree of electrical insulation is low, and the production cycle is lengthened. Cause the high cost of manufactured produc...
