Abstract
The invention discloses polyurethane modified silicone rubber and a preparation method thereof. The invention has the advantages that: the anti-aging silicone rubber material for producing the surface three-dimensional printing of the elastic fabric is prepared by modifying the methyl vinyl terminated silicone rubber by adopting a polyurethane silane coupling agent and adding a certain amount of white carbon black, hydroxyl silicone oil, active aluminum hydroxide, pigment, an auxiliary agent and the like.
Description
Technical Field
The invention relates to polyurethane modified silicone rubber for the surface of high-elasticity fabric and a preparation method thereof.
Background
The traditional silicon rubber has good initial viscosity, can keep good elasticity for the initial period of time (within 1 year) after being used on high-elasticity fabric, and the problems of cracking, peeling and the like of the silicon rubber can not be caused by pulling and wrinkling of clothes, but with the increase of the service time, the adhesive force of the common silicon rubber on the fabric begins to be reduced under the action of ultraviolet rays and various external environments, and the common silicon rubber also begins to be hardened, so that peeling is easily generated, and the defects on the surface of the fabric are caused.
Polyurethane is used as common high-elastic resin, the adhesive force of the polyurethane to the fabric is superior to that of silicon rubber, but the polyurethane is not suitable for being used as a resin decorative coating on the surface of the high-elastic fabric due to poor aging resistance, easy yellowing and embrittlement; therefore, aiming at the fields of high-grade sportswear, hair bands and the like, the invention provides a preparation method of polyurethane modified silicone rubber, aiming at the problems that a rubber with high elasticity, high adhesive force and high weather resistance, which can be used for a long time, is lacked, and the invention can simultaneously prolong the service life of the silicone rubber and improve the adhesive force to fabrics.
