Problems solved by technology

[0004] Chinese patent (00811449.8), the invention relates to a curable silicone coating composition, especially a silicone coating applied to textile fabrics, the silicone coated fabric is especially suitable for the manufacture of inflatable safety shock absorbers , such as airbags, parachutes, or geotextiles for construction. Compared with the present invention, the curing method is different. It adopts traditional thermal curing, and heavy metal catalysts (such as platinum catalysts, organic titanium catalysts) need to be added to the coating. Compared with the radiation of this patent Curing method, high energy consumption and cost, and product applications are also different
[0007] Among the reported patents, the low-energy electron beam radiation curing technology has not been applied to textile coated fabrics. In the reports of silicone-coated fabrics, most of them use traditional thermal curing methods, which not only consume high energy, but also add precious metal catalysts. The cost of raw materials is high, and the coating is generally a solvent system, and the solvent volatilizes during the curing process, causing certain pollution to the environment

Abstract

The invention relates to a method for radiation curing of a pure organic silicone coated fabric by using electron beams. The method comprises the following steps of: dispersing vinyl silicone oil, dimethyl silicone oil, hydrogen-containing silicone oil, a silane coupling agent, trimethylolpropane triacrylate, nanoscale silica, a flatting agent and a surface active agent in a vacuum kneading machine, mixing evenly to obtain a coating, finishing a fabric with certain humidity by a rubber blanket preshrinking machine, hot pressing the fabric through a hot pressing roller of a mirror glazing calendar to obtain base cloth, evenly coating the coating on the base cloth, and placing the base cloth on a transmission beam rack of a low-energy electron accelerator through a transmission roller for radiation curing to obtain the fabric. The fabric produced by the method is silky and soft in hand feel, waterproof, anti-seepage, and good in breathability and moisture permeability, and can be widely used in clothing, outdoor, fashionable fabrics and the like; the clothing does not have wrinkles, is easy to iron, and has stretching and recovering properties, and outdoor textiles can withstand the invasion of sun, wind and water; and the coating provided by the invention does not contain any solvent, and is environment-friendly, safe, non-toxic, pollution-free, simple in preparation technology, convenient in operation and construction, and low in energy consumption.

Description

technical field [0001] The present invention relates to a method of curing pure silicone coated fabrics by electron beam radiation. Background technique [0002] In recent years, the main reason for the continuous development of electron beam curing technology is its product quality and economic benefits. Compared with other curing methods, electron beam curing has greatly improved production efficiency and improved physical properties of cured products. It is a kind of Room temperature curing technology, low energy consumption, no volatilization, zero emissions, no pollution to the environment, is a new type of environmentally friendly curing technology. Electron beam curing technology is widely used in the fields of telecommunication cables, ink printing, wood spraying, medical food disinfection, etc., but it is rare to apply it to textile fabric finishing. A small amount of electron beam curing fabric coating technology has appeared abroad, but due to its technology It i...
