Modification Of Waterborne Polyurethane Leather Finishing Agent

Select 10g attapulgite clay, add 100ml of hydrochloric acid with a concentration of 1mol / L to the clay, mix the two, stir for 24 hours, and then cool them down. Then, the filtrate is washed with distilled water so that the filtrate no longer contains chloride ions. The filtrate is dried in an oven with a temperature of 100 ° C. after waiting for 24 hours, it is ground into powder. Thus, the acid treated attapulgite is obtained.

Modification Of Waterborne Polyurethane Resin Lotion With Attapulgite

Prepare the acid treated attapulgite into a dispersion with a mass fraction of 10%, employ electromagnetic stirring for two hours, and then conduct ultrasonic dispersion for one hour. Then, add aqueous polyurethane resin lotion into the dispersion under stirring conditions, wherein the mass fraction of aqueous polyurethane resin lotion is 20%, The content of the acid treated attapulgite is controlled to be between 0.1% and 5% of the water-based polyurethane resin lotion, the two are allowed to react at 70 ℃ for four hours, and then the product is concentrated to about 20% by using a rotary evaporator. Thus, the modification of the water-based polyurethane resin lotion by using attapulgite clay is initially realized. Subsequently, the film was made with the application of the modified product, and 20g of the product was put into the mold of polytetrafluoroethylene to achieve film making.
