Problems solved by technology

The matting effect of the paint surface naturally also depends on the amount of matting agent, in view of the precipitation of SiO 2 In addition to its matting effect, it also leads to an increase in paint viscosity, thus allowing SiO 2 The share in the paint is limited
At the same time, precipitated silica is artificially synthesized, and the resource and energy consumption of raw materials and product manufacturing are relatively large, and the price is relatively expensive.

Embodiment 1

[0030] In the present invention, the powdered quartz mineral raw material after mining and selection is firstly processed, added with water and stirred to make pulp, and then added grinding aid to continue stirring through multiple series-connected stirring mills, a part of the raw material is directly press-filtered, and the other part of the raw material is then added with acid and bleached After washing, press filtration is also carried out. The raw material after pressure filtration can be dried and dehydrated to directly obtain high-crystalline micro-silica powder, or after drying and dewatered, synthetic wax can be added to obtain modified micro-silica powder after surface modification. Silica fume. The modifying agent can be polyethylene wax, the dosage is 1-2%, the modification temperature is 80°C-90°C, and the modification time is 20-40min. Material particle size ≤10μm.

[0031] This product has good matting performance and can be used in paints and inks. It is an id...

Embodiment 2

[0033] The usage method of the present invention:

[0034] First wet the powder quartz high-efficiency matting agent with a solvent, add it to the resin, and disperse it in a high-speed disperser for 10-15 minutes, the dispersion speed is 1000-1200 rpm, and the line speed is about 5m / s.

[0035] Amount added:

[0036] Semi-gloss: 3-5% by weight

[0037] Matt: 6-10% by weight.

Abstract

An efficient flatting agent based on SiO2, its production and use are disclosed. It's simple and cheap and has excellent fatting performance. It can be used in pigment and ink.

Description

technical field [0001] The present invention relates to an "environmentally friendly" mineral raw material - powdered quartz (SiO 2 ) efficient matting agent and its preparation and application in inks and paints. Background technique [0002] Flatting agent, also known as flatting agent, is a kind of agent that can matt paint without affecting its surface roughness. The gloss of the coating film is due to the refraction of light to the surface of the paint film and reflection at a certain angle, which can be direct or scattered. In order to reduce the gloss of the coating film, the surface of the coating must have a certain roughness, so that the reflection becomes scattering. The matting agent is either suspended on the surface of the coating or filled in the interior of the coating system, which causes the surface of the coating film to have different degrees of roughness, scatters the penetrating light in the coating, and then scatters from the surface of the coating f...
