Problems solved by technology

However, the water resistance of asbestos yarn produced by the wet method is often difficult to achieve the ideal state, which makes the asbestos cloth woven from it unable to achieve the ideal water resistance. After contacting water, it is easy to colloid again, and the asbestos fiber is easily deformed by external force. will return to the dispersed state, thus rendering the asbestos cloth useless

Abstract

The invention discloses a processing technology of composite high-molecular heat-insulation water-resistant asbestos cloth. The processing technology comprises the following steps of (1) mixing asbestos fibers with water and sodium diethylhexyl sulfosuccinate, and soaking the asbestos fibers, the water and the sodium diethylhexyl sulfosuccinate; (2) putting the soaked asbestos fibers into a pulping machine, and pulping to form pulp; (3) feeding a slurry into a hot water tank filled with solidification liquid to obtain a colloidal asbestos slurry, and adding caustic soda into the hot water tank until the pH value of the hot water tank reaches 10 to 12; (4) solidifying the colloidal asbestos slurry into a film through a film forming machine, and twisting to form asbestos yarns; and (5) immersing the asbestos yarns into waterproof coating liquid, drying, and spinning to obtain the asbestos cloth. According to the asbestos cloth processed by the asbestos cloth processing technology provided by the invention, the heat insulation performance is not influenced, the water resistance is obviously improved, and the use performance is obviously improved.

Description

technical field [0001] The invention belongs to the technical field of asbestos cloth production, and in particular relates to a processing technology of composite polymer heat-insulating and water-resistant asbestos cloth. Background technique [0002] Asbestos cloth is a cloth woven from asbestos fibers. It has good fire resistance and heat insulation properties, and is often used as heat preservation and heat insulation materials for various equipment or processed into other asbestos products. [0003] If the asbestos cloth is produced by the dry method, it needs to be loosened, high-temperature fusing and remolded. The dust in the whole production process is large, and the product is easily damaged and the fibers fall off. After the asbestos fibers fall off, they are easily inhaled by the human body, causing people who come into contact with them to die. Symptoms such as pneumoconiosis or skin itching are extremely harmful to human health. Therefore, the current commonl...
