Problems solved by technology

[0003] Existing silicone rubber coated fabrics are coated with fully vulcanized silicone rubber coatings on one or both sides. Fabrics with this coating can only be made simply by cutting and sewing because the coating has been fully vulcanized. Shaped products have no replasticity and cannot be vulcanized into products with overall different interlayer structures and different appearance shapes
And the products obtained by sewing have low strength and leakage, which limits their scope of use

Embodiment 1

[0021] Prepare 140 kg of semi-vulcanized rubber solution.

[0022] 1) Choose flame-retardant methyl vinyl silicone rubber (manufacturer: Jiangsu Hongda Chemical New Material Co., Ltd., brand name: HD-8961), weigh 40 kg with ferric oxide (Fe 2 o 3 ) 2 kilograms of color masterbatches are put into the kneader, add 40 kilograms of 200# gasoline and stir, the stirring speed is 30 rpm, and the stirring time is 2 hours;

[0023] 2) Take by weighing 8 kilograms of 200# gasoline, in a high-speed stirrer, slowly add 4 kilograms of Al2O3 while stirring, to obtain Al2O3 suspension;

[0024] 3) Use modified phenol novolak resin (manufacturer: Cytex Corporation, brand: PN759) as the adhesive, weigh 3 kg, select 2,5-dimethyl-2,5-di-tert-butyl peroxide Hexane oxide is a semi-sulfurizing agent, weigh 4 kilograms, and drop into a kneader simultaneously with the aluminum oxide suspension prepared in the above-mentioned operation, stir evenly, and the stirring speed is 30 rpm, and the time is ...

Embodiment 2-3

[0027] See Table 1 for the formula of the semi-vulcanized glue solution, and the preparation method is the same as in Example 1.

[0028] Table 1: Example 2-3 semi-vulcanized glue formula

[0029] Component names and process conditions

Embodiment 4

[0031] Fabrication of semi-vulcanized silicone rubber coated fabrics on one side.

[0032] 1) The substrate treated with the coupling agent is passively unwound from the unwinder 1, and enters the magnetic powder tensioner 3 to adjust the tension, and then the substrate is scraped at the scraping head 4, and the gap between the scraping heads is adjusted to 90 wires; Pass through laminating machine 15 again, finish drying process in baking oven 16, and drying temperature is 70 ℃, and the baking time of control product in baking oven is 4 minutes, finishes cooling in two roller cooling 17, passes separator 20 again Guide, and finally pass through the guide roller 19 on the winder 18 and apply a layer of 3-wire polyethylene isolation film to complete the winding or complete the winding on the winder 22 through the guide roller 21;

[0033] 2) Place the above-mentioned finished coil on the unwinder 1 of the unit again, with the semi-vulcanized rubber facing up, set the polyethyle...

Abstract

A semi-sulfurized silicon rubber coated fabric used to prepare the high-strength impervious seamless shaped product is composed of a fabric substrate and a coated semi-sulfurized silicon rubber layer prepared proportionally from raw methylvinyl silicon rubber, acylane-type organic per oxide as sulfurizer, phenolic resin as adhesive and hydrocarbon or benzene type organic solvent. Its coating process includes such steps as recoiling, controlling tension, scraping material, baking at 30-100 deg.C for 4-10 min, sticking an isolating film, and coiling.

Description

technical field [0001] A semi-vulcanized silicone rubber coated fabric belongs to the field of silicone rubber coated fabrics, and in particular relates to a semi-vulcanized silicone rubber coating formula and a coating method. Background technique [0002] Silicone rubber coated fabric is a kind of composite material with excellent performance. It has the properties of temperature resistance, chemical corrosion resistance, water impermeability, and oil resistance. It can be widely used as sealing material, flame retardant material, and insulating material in electricity, construction, and fire protection and other industries. [0003] The existing silicone rubber coated fabric is coated with fully vulcanized silicone rubber coating on one or both sides. The fabric with this coating can only be made by cutting and sewing because the coating has been fully vulcanized. Shaped products have no replasticity and cannot be vulcanized into products with overall different interlaye...
