Embodiment 1
[0026] A process for processing composite polymer heat-insulating and water-resistant asbestos cloth, comprising the following steps:
[0027] (1) Soak asbestos fiber after mixing with water and dioctyl sulfosuccinate sodium salt, wherein the mass ratio of cotton fiber, dioctyl sulfosuccinate sodium salt, and water is: 1:0.14:12;
[0028] (2) putting soaked asbestos fibers into a beater to form a slurry, wherein the soaked asbestos fibers have a weight ratio of 4.5:100 to water when beating;
[0029] (3) Send the slurry into a hot water tank equipped with coagulating liquid to obtain colloidal asbestos slurry, wherein, add caustic soda in the hot water tank until the pH value of the hot water tank reaches 10-12, of course the coagulating liquid can be soap liquid ;
[0030] (4) The colloidal asbestos slurry is solidified into a film by a film forming machine, and an asbestos yarn is formed after twisting;
[0031] (5) Dip the asbestos yarn into the waterproof coating solutio...
