Problems solved by technology

[0002] At present, leakage is most likely to occur at the overlapping joints of adhesive tape products during production. The general method to prevent leakage is to stick adhesive strips at the overlapping joints. This method has the following problems: First, there is a certain gradient (step) at the overlapping joints. It makes the adhesive strip not fit firmly, and it is difficult to achieve the real anti-leakage effect
The second is that the rubber strip has a certain thickness (about 1.1mm), which affects wearing and affects the appearance quality
The third is that the process of laminating the rubber strip is complicated. First, the glue should be applied to the rubber cloth and the glue strip separately, and then the glue should be dried before lamination and then vulcanized.

Embodiment 1

[0021] 1. Ingredients:

[0022] Neoprene 100kg, sulfur 0.2kg, accelerator M0.2kg, accelerator NA-220.2kg, zinc oxide 2kg, magnesium oxide 2kg, paraffin wax 4kg, pine tar 4kg, antioxidant H0.2kg, Vaseline 4kg, engine oil 10kg, high wear-resistant carbon black 20kg, calcium carbonate 40kg, coloring agent 0.5kg.

[0023] 2. Mixing and tableting:

[0024] First wrap the neoprene rubber on the open mill without holes, then add other prepared materials and knead evenly to produce a sheet.

[0025] 3. Beating:

[0026] First add 206kg of butyl acetate into the beater, and then add the prepared mixed film for beating. After the glue is ready (no grains and lumps), add 19 kg of mixed oil of 50% each of butyl acetate and No. 120 solvent gasoline, and adjust the glue concentration to 15 seconds.

[0027] 4. After passing the inspection, make a spare and use it up within 72 hours. When the room temperature is lower than 18°C, the glue must be kept warm, and the heat preservation temp...

Abstract

The invention relates to a mucilage for producing rubber coated fabric products, in particular to an anti-infiltration mucilage for rubber coated fabric products. The mucilage is prepared from the following raw materials in portions by weight: 100-120 portions of neoprene, 0.2-0.7 portion of sulfur, 0.2-0.7 portion of accelerator M, 0.2-0.7 portion of accelerator NA-22, 2-7 portions of zinc oxide, 2-6 portions of magnesium oxide, 4-6 portions of paraffin, 4-6 portions of pine tar, 0.2-0.7 portion of anti-aging agent H, 4-6 portions of vaseline, 10-15 portions of machine oil, 20-35 portions of high abrasion furnace black, 40-60 portions of calcium carbonate and 0.5-1.0 portion of colorant. The mucilage is prepared from the neoprene, and ultra-fast accelerators are used in the formula, so that the mucilage can be naturally vulcanized at room temperature, thereby omitting the high-temperature vulcanizing process in the original process, reducing the investment for equipment and barrack capital and reducing the energy consumption at the same time. When being used for the rubber coated fabric products, the invention has the advantage of favorable anti-infiltration effect and enhanced product percent of pass. The colorant is added into the formula, so that the color of the mucilage is the same as that of the rubber coated fabric products, and the mucilage does not affect the product appearance.
