Dry-mixed mortar dust-proof agent and dry-mixed mortar containing same
The invention provides a dry-mixed mortar dust-proof agent which can reduce dust generated in the production, transportation and application processes of dry-mixed mortar. The dust-proof agent is obtained by adopting a dry powder blender for stirring in advance and uniformly mixing, by weight, 55-85% of fibers and 5-15% of bentonite, and then spraying 10-30% of silicone oil uniformly into a mixture in the stirring process, wherein the fibers are obtained by pulverizing natural wood chips, halm or straw into powder with the diameter ranging from 0.1 mm to 0.5 mm, then soaking the powder in hot water for two hours at the temperature ranging from 90 DEG C to 100 DEG C, and finally conducting the drying. According to the dust-proof agent, the cost is low, the additive amount is small, dust generated by other raw materials of the dry-mixed mortar can be well adsorbed, dust generated in the dry-mixed mortar production and application processes can be effectively reduced, net structures can be formed in the hardening process of the mortar, and cracks in the hardening process of the mortar can be greatly reduced. The invention further provides the dry-mixed mortar containing the dust-proof agent, and the mortar comprises 12-40% of inorganic cementing materials, 60-85% of aggregate, 0.8-2.0% of additives and 0.6-0.8% of the dust-proof agent.
