Embodiment Construction

[0014] 1) Glue compounding process: Weigh 1.5Kg benzophenone, 20Kg rubber and 3.1Kg acrylic glycolic acid to mix, add 400g gasoline and stir evenly to make a rubber solution and mix it for later use;

[0015] 2) Coating process: use a calender to evenly coat the rubber layer liquid on the base cloth, the speed of the calender is 500 rpm, the feeding speed of the base cloth is 1 m / min, and the thickness of the obtained rubber coating is 500 grams / square meter;

[0016] 3) Curing process: using two kinds of ultraviolet light waves to irradiate twice, the irradiation wavelength of the irradiator 1 ultraviolet light is 250 nanometers, the irradiation wavelength of the irradiator 2 ultraviolet light is 400 nanometers, and the total irradiation energy is 900 millijoules / square meter.

[0017] 4) Winding process: the finished product is wound by the cloth guide roller.

Abstract

A process of optically solidifying a rubber coating, especially under ultraviolet radiation. Photosensitive agents are added into the rubber coating and solidified under ultraviolet radiation. Photosensitive agents of the invention are agents inducing free radicals, such as biethoxy hypnone, benzophenone, bibenzoyl. Additives are acylic carboxyethyl ester or the like, and so on. Compared with thecurrent process of solidifying rubber, since the photosensitive agents could absorb energy of ultraviolet radiation in a short time, the rubber coating could be solidifies quickly, which simplify theprocess, and save cost.

Description

technical field [0001] The photocuring process of a rubber coating relates to a curing method of a rubber coating, in particular to a method for curing a rubber coating by means of ultraviolet light irradiation. Background technique [0002] Coated fabric is an important branch of textile products. The function of coating is to make up for and improve the insufficiency of the original textile products, so as to expand the application field. [0003] The base fabric product with rubber coating is light in weight, anti-corrosion, good in insulation performance, excellent in elasticity and flexibility, and flame retardant. It is suitable for making insulating cloth, sleeves, and flexible connectors for pipes, and can also be used as Anti-corrosion materials, building sealing materials, high-temperature anti-corrosion conveyor belts and packaging materials, etc., are widely used. [0004] The existing curing method of coated rubber products is: in the compounding process, add a...
