Problems solved by technology

The release agent used in the drying process of decorative boards has always been based on animal oil. The disadvantage is that it is inconvenient to use and needs to be melted before application; The pungent smell pervades the workshop, which not only pollutes the air and the environment, but also penetrates into the mineral wool sheet layer due to the smell of animal oil, affecting product quality and export earnings; third, the cost is too high. As we all know, animal oil At least 4,000 yuan per ton, which virtually increases the cost of the mineral wool board

Abstract

The invention provides a synthetic material to be used as the releasing agent of mineral wool sound-absorbing decorative panel for substituting animal oil and fat, and its preparing process, wherein the material comprises (by weight ratio) stearic acid 1-2, sulfuric acid castor oil 0.5-1.2, polyoxythylene fatty alcohol ether sodium sulfate 0.9-1.8, water-soluble silicon oil 0.3-0.8, polyacrylamide 0.1-0.4, urea 2-6, pentaerythritol 0.8-1.6, metal surface protectant 0.2-0.3, EDTA 0.4-0.6, and balancing water.

Description

technical field [0001] The invention relates to a synthetic release agent and a preparation method which can replace conventional animal oil release agents in the production of mineral wool sound-absorbing decorative panels, and belongs to the technical field of additive preparation for mineral wool manufacturing. Background technique [0002] The production method of the mineral wool sound-absorbing decorative board in the prior art is based on mineral wool, supplemented by cornstarch, glass short fiber, sepiolite, zinc acetate, boric acid, borax, bone glue, paraffin, stearic acid, Dozens of inorganic and organic chemical raw materials such as polyacrylamide are formed by beating, trough, raceway, and rolling, and then they are held up by iron plates one by one, filled in an oven one by one, dried and cut. The release agent used in the drying process of decorative boards has always been based on animal oil. The disadvantage is that it is inconvenient to use and needs to be ...
