Problems solved by technology

[0002] Chlorinated paraffins are used in paints, chlorinated rubber and styrene-butadiene resin coatings. In plastics, they are used as flame retardants, binders, cementing agents and fillers, and can also be used as lubricating additives. They also have Moisture resistance and chemical resistance, it can also be used in surface treatment agents for fabrics and packaging materials to improve the flame and fire resistance of fabrics and packaging materials, however, the chlorinated paraffins currently used for fabric treatment can achieve resistance The flame retardant effect is poor, and it cannot achieve a good flame retardant effect when used alone. At the same time, the chlorinated paraffin currently available on the market for fabric treatment has a single function. In addition to flame retardant and lubricating effects, it is difficult to further improve the quality of the fabric. Therefore, the purpose of the present invention is to study a kind of chlorinated paraffin with better flame retardancy and more functions, which is specially used for fabrics.

Abstract

The invention discloses a preparation method of special chlorinated paraffin for the surface treatment of a fabric. The preparation method comprises the following steps: treating solid paraffin by adopting phosphoric acid, then preparing chlorinated paraffin by adopting a chlorine method, then blending the chlorinated paraffin and pentaerythritol, performing the catalytic reaction in the presenceof p-methylbenzene sulfonic acid, thus obtaining phosphate modified chlorinated paraffin, then dispersing the phosphate modified chlorinated paraffin into dimethyl carbonate, and blending with modifying ester amine to react, thus obtaining the quaternization modifying chlorinated paraffin. Triethanolamine is treated by adopting hexabromocyclododecane, so that the surface hydrophobic performance ofthe fabric is effectively improved; and the quaternization modified chlorinated paraffin is used for treating the fabric, so that the softness, electrostatic resistance, sterilization performance, and yellowing resistance of the fabric can be effectively improved.
