preparation example Construction

[0020] The preparation method of this automotive interior material mainly comprises the following steps:

[0021] 1) Base fabric pre-finishing: the base fabric is made of viscose fiber woven fabric with a thickness of 0.4~0.7mm or chemical fiber and cotton blended twill woven fabric with a thickness of 0.5~0.8mm. Combustible impregnation finishing, the concentration is 0.1~5%, the pH value is 6~7; then pre-drying, the temperature is 100℃~130℃, the time is 1~3min; then the temperature is 150℃~200℃, the time is 2~5min Baking and fixing under certain conditions, and finally cooling and winding to prepare the solidified coating for use;

[0022] 2) Wet coagulation coating: After the pretreated base fabric is calendered, sizing and scraping coating on the coating machine, the sizing amount is 100~300g / m 2 , dry weight; then through the coagulation tank solidification molding, coagulation tank dimethylformamide (DMF) concentration of 15-25%, coagulation bath temperature 20-30 ℃, co...
