Embodiment Construction

[0018] The present invention will be described in detail below in combination with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the teachings of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of the present application.

[0019] A nanometer additive, which is a colloid, and the colloid is prepared from inorganic silicate mineral material. The crystal form of the inorganic silicate mineral material is one of fibrous, flake or crystal. The colloid is composed of nanofibers and nanometer mineral particles. The nanofibers have a diameter of 20-50nm and a length of 5-10nm. The nanofibers are cross-stacked to form a fiber network, and t...

Abstract

The invention discloses nano additive which is colloid. The colloid is prepared from inorganic silicate mineral materials. The nano additive is obvious in suspension effect, and the storage stability and the can opening effect of water-based paint are improved; nano fiber network ensures that titanium dioxide particles cannot be agglomerated easily, the dispersion degree of the titanium dioxide is guaranteed, and the shielding effect of titanium dioxide in the water-based paint is improved; the physical and mechanical performance of a film is improved in the presence of the nano fiber network and nano ore body particles, and light scattering power is improved, so that the contrast ratio of the film is improved; the resistance, particularly the water resistance of the film is greatly improved; and the adhesion, the flatness and the smooth finish of the film are improved through the permeability and the filing effect of nano particles.

Description

technical field [0001] The invention relates to an additive, more precisely a nanometer additive. Background technique [0002] Nanomaterials have new physical and chemical properties that homogeneous (macroscopic) materials do not have. Such as: the bactericidal effect of nano-silver and nano-copper, the photocatalytic effect of nano-titanium dioxide; the reinforcing effect of nano-light calcium; A series of corresponding water-based nano coatings can be developed, such as: high-efficiency sterilization, anti-fog coatings, photocatalytic self-cleaning exterior wall coatings; anti-stone chip coatings for automobile chassis, etc. However, the anti-agglomeration of these nano-powders in specific applications must be separately dispersed and formulated into a water suspension before being used in a water-based system, and the function is single and the pertinence is relatively strong. Contents of the invention [0003] Due to the above-mentioned shortcomings of the prior ar...
