The ingredients in the formulation are further explained in the present invention:
heavy calcium powder, called heavy calcium for short, is a white powder prepared by using high-quality calcite (calcium carbonate content is more than 98%) as a raw material and processing the calcite into white powder by a lime mill, and the main component of the heavy calcium powder is calcium carbonate, so that the production cost can be reduced, and the toughness and the strength of the product can be increased.
The air entraining agent is used for improving the workability, water retention property and cohesiveness of the concrete mixture and improving the fluidity of the concrete, and a large amount of uniformly distributed, closed and stable additives of micro bubbles are introduced in the mixing process of the concrete mixture, so that the using performance of the putty is improved and the construction hand feeling is improved.
The thixotropic agent can ensure that the glue solution has higher consistency when being static after being added, and becomes a low-consistency fluid substance under the action of external force, has the function of ensuring that after thick paste is applied to a wall, the wall surface is not uneven due to sagging caused by the self gravity, and can become low-consistency paste in the batch scraping process, so that the batch scraping can be performed easily.
The starch ether improves the viscosity stability due to the etherification of the starch, is not easy to hydrolyze under strong alkaline conditions, is suitable for building dry mixtures such as mortar, plastering and the like, and can endow higher thickening property, stronger structural property, sagging resistance and easy operability when being used in the building dry mixtures.
The water-retaining agent is made of high water absorption resin which is a functional polymer material with extremely strong water absorption capacity.
The retarder is an additive for prolonging the hydration speed and the hydration heat of gypsum and the setting time of the gypsum, and aims to prolong the hydration hardening time of mortar, so that the freshly mixed mortar can keep plasticity for a long time, and the setting time of the freshly mixed mortar is adjusted.
The polyvinyl alcohol particles are mainly used for increasing the bonding performance of the product, the hardness of the product after the product is dried on the wall is ensured, the phenomena of hollowing and the like can not occur after the product is dried on the wall, the toxicity of the raw material is mainly harmful to the human body after the raw material is absorbed into the human body, but the raw material is less in the adding amount of the product and odorless, can not be absorbed into the human body and can not be harmful after being directly contacted with the skin, and after the material is added into the wall, the raw material can not volatilize along with the moisture and can move to all parts of the product along with the moisture, so that the effect of increasing the strength is achieved.
The product of the invention is used on the inner wall, basically does not contact with water, and the dissolution efficiency of the raw material and cold water is extremely low, so the raw material can increase the strength under normal conditions and can not migrate into the air to cause harm to human bodies.
The mildew inhibitor is one kind of high molecular material additive capable of inhibiting the growth of mildew and killing mildew, and can protect high molecular material from being corroded by fungi and maintain excellent appearance and physical and mechanical performance.
