Abstract

The invention provides a calcium carbonate surface-active agent and relates to a modifying agent used for calcium carbonate, and further provides a preparation method and using method thereof. The surface-active agent comprises the following components: stearic acid, isopropyl alcohol, ethylene-glycol, diethylene glycol monobutyl ether, isooctyl alcohol, aluminic acid ester, amino silicone oil, sorbitan monolaurate and polyoxyethylene sorbitan monolaurate. The activator modified calcium carbonate has an unprecedented effect; scagliola produced through filling of calcium carbonate is greatly improved in strength, rigidity, rigidity, especially shock resistance and scratch resistance, and is more compact and smoother. Meanwhile, the activator is low in cost; when the activator is added in a powder vertical mill for grinding the calcium carbonate to 600-mesh fine powder, 40 Yuan more is required for every ton of the calcium carbonate; and moreover, a DOP oil absorption value is smaller than 12, so that the economic benefit of the scagliola processing is greatly improved.

Description

technical field [0001] The invention relates to a modifying agent for calcium carbonate, a preparation method and a use method thereof. Background technique [0002] As an important chemical raw material, calcium carbonate is widely used in the production of artificial marble, paper, paint, plastics, cosmetics, etc. With the improvement of people's requirements for product quality, the requirements for the fineness and uniformity of calcium carbonate are also increasing. For the production and application of ultrafine calcium carbonate, surface modification is particularly important. Because the particle size of ultrafine calcium carbonate becomes small, the number of surface atoms increases, the surface energy increases, the adsorption effect is enhanced, and the particles tend to agglomerate each other, which leads to the particles not being well dispersed in the polymer matrix; at the same time, calcium carbonate The commonality of hydrophilic and oleophobic makes it ea...
