Embodiment Construction

[0015] Please refer to figure 1 , Is a flow chart of making a rubber layer in an embodiment of the present invention. It includes the following steps:

[0016] First, proceed to step S10 to provide a rubber composition. The rubber composition includes at least 40 to 60 parts by weight (PHR) of natural rubber, 20 to 40 parts by weight of neoprene rubber, 20 to 40 parts by weight of ethylene propylene rubber, and 100 to 200 parts by weight of inorganic filler , 5 to 20 parts by weight of organic filler, and 2 to 5 parts by weight of vulcanizing agent.

[0017] Among them, the inorganic filler is selected from one of the group consisting of calcium carbonate, clay, calcined clay and their mixtures; the organic filler is selected from the group consisting of stearic acid, resin, petrolatum and their mixtures. Kind of. The vulcanizing agent is selected from one of the group consisting of sulfur, organic accelerator and zinc oxide. Organic or inorganic fillers can increase the hardne...

Abstract

The invention provides a rubber composition and a method for fabricating a rubber layer and a double-sided rubber composite layer. The method for fabricating the double-sided rubber composite layer comprises the steps of providing a base cloth having opposite upper surface and lower surface; immersing the base cloth in an adhesive; coating a first adhesive layer and a second adhesive layer on the upper surface and the lower surface respectively; making a first rubber layer and a second rubber layer with the thickness of 0.07-0.1 cm; coating the first rubber layer and the second rubber layer on the first adhesive layer and the second adhesive layer respectively; and finally carrying out sulfidizing treatment to cure the first rubber layer and the second rubber layer.

Description

Technical field [0001] The invention relates to a rubber composition and its application, and more particularly to a rubber composition and a method for manufacturing a rubber layer using the composition. Background technique [0002] Nowadays, the application of thin rubber products is more and more extensive, for example, as the main material of flame-resistant protective clothing, industrial raincoats, and medical bedspreads. However, thicker and heavier rubber materials are still used on the inflatable raft products. Therefore, the weight of the finished product will cause the load of the ship. In the existing rubber industry, since rubber cannot be processed at excessively high temperatures, it is technically difficult to thin the rubber to 0.1 cm. In addition, the rubber leather used as inflatable raft products has high requirements for air tightness, adhesion, mechanical strength, oil resistance, water resistance, UV resistance, and cold resistance, so it is suitable for ...
