Problems solved by technology

[0003] With the specialization and nanometerization of calcium carbonate particles, its own defects greatly limit its application: one is CaCO 3 The smaller the particle size, the more atoms on the surface, the higher the surface energy, the stronger the adsorption, and the mutual agglomeration between the particles; the second is CaCO 3 As an inorganic filler, the particle surface is hydrophilic and oleophobic, has poor affinity with organic polymers, and is easy to form aggregates, resulting in internal defects and poor mechanical properties of polymers.

Abstract

The invention relates to the technical field of surfactants, and in particular relates to a macromolecule composite fat powder surfactant as well as a preparation method and an application thereof. The macromolecule composite fat powder surfactant comprises the following raw materials in percentage by weight: 5-15% of distearoyl isopropoxy aluminate, 8-15% of butyl stearate, 10-25% of glycerin monostearate, 50-70% of aliphatic ester and 2-6% of antioxidant. The surfactant is a multifunctional product with integrated functions of coupling, dispersion and lubrication, is large in reaction activity with surface of CaCO3 powder, light in color, non-toxic and small in odor and has the effect of improving the processing fluidity and the physical and mechanical properties of a CaCO3 packing system.

Description

technical field [0001] The invention relates to the technical field of surface treatment agents, in particular to a polymer composite fat powder surface treatment agent and its preparation method and application. Background technique [0002] The processing technology and application technology of calcium carbonate powder in my country has been developing rapidly, and it has been widely used in plastics, rubber, coatings and other polymer products industries. Calcium carbonate powder is added as a filler, which can reduce the cost of the product. Adding calcium carbonate to plastic can play the following roles: 1. Increment, reduce cost; 2. Improve the heat resistance of plastic products, adding 40% CaCO to polypropylene 3 , its heat distortion temperature can be increased by about 20oC; 3. Improve the astigmatism of plastics, play a role in shading or extinction; 4. Improve the electroplating performance or printing performance of plastic products; 5. Reduce the dimensiona...
