[0024] The present invention provides a kind of preparation method of tactile oil, comprises the following steps:

[0025] (1) Mix polyether diol and polyester diol uniformly at 100°C-105°C. The polyether diol includes polyoxypropylene diol and polytetrahydrofuran diol with an average molecular weight of 3000-4000 Alcohol, polyester diol is polycaprolactone diol with a molecular weight of 3500-4500, and the weight ratio of the three raw materials in the mixed diol is 10%-15% of polyoxypropylene diol, polytetrahydrofuran diol 5%-10%, polycaprolactone diol 75%-85%; vacuumize at 100℃-105℃ for 1-2 hours to remove the water in the mixed diol. Mixed use of three diols, both polyether type and polyester type, can make the crystallinity of the soft segment reach 35%-45%, and the glass transition temperature is 65°C-70°C, the soft segment has recoverability;

[0026] (2) Cool down to 85°C-90°C, add isophorone diisocyanate to react for 2-3 hours under nitrogen protection, the amount a...

Abstract

The invention provides touch oil and a preparation method for a touch membrane utilizing the same. A preparation method for the touch oil comprises the following steps of: performing a polymerization reaction on mixed dihydric alcohol containing polyester diol and polyether glycol and isophorone diisocyanate; further reacting with a hydrophilic chain extender, a cross-linking agent and the like in the presence of a catalyst so as to form a polyurethane prepolymer; adding the prepolymer and deionized water into a dispersion machine, and performing emulsion dispersion; and mixing with a nano aluminum oxide aqueous solution, a flatting agent and ultraviolet absorbent, thereby obtaining the touch oil. The invention further provides a preparation method for a touch membrane utilizing the touch oil. The touch membrane is obtained in roller coating, a coating is sufficiently cured in a drying tunnel and is sufficiently crystallized in a third segment, so that the touch effect of the hot-pressed coating does not disappear. The touch method prepared by the preparation method can be applied to thermal gluing of an automotive trim plate, and has the advantages of good abrasive resistance, high light transmittance, no disappearing of touch feeling after hot-pressing, and the like. The method provided by the invention is capable of facilitating large-scale production and improving construction environments.

Description

technical field [0001] The invention belongs to the technical field of functional polymer films, and more specifically relates to a tactile oil and a preparation method for a tactile film using the tactile oil. Background technique [0002] With the rapid development of the domestic automobile industry, more and more new materials are used for car interior decoration. In order to eliminate the dizziness caused by the reflection of decorative materials such as car interior panels, engineers and technicians have adopted the method of spraying soft-feeling paint, so that the car panels have a silky feel and soft light reflection function. Although R&D personnel try to use low-toxicity solvents, it still brings harm to construction personnel, and the quality of spraying has a great influence on the final product, and the qualified rate is low. [0003] Tactile film, also called soft film, is a special matte film with special velvet smooth surface and delicate touch. It is main...
