Abstract

The invention provides a bentonite assistant. The bentonite assistant comprises, by weight, 33-42% of bentonite, 7-12% of mica, 12-18% of phosphoric acid, 5-11% of silica sol, 10-12% of alumina, 1-6% of magnesium oxide and 2-8% of calcium oxide. Above components are reasonably mixed to improve the refractoriness of a coating and to make the coating have good dispersion and good crack resistance; compared with assistants in the prior art, the bentonite assistant provided by the invention has the advantages of 30-50%increase of the coating refractoriness, 20-35% increase of the dispersion parameter, 10-30% increase of the crack resistance, 10-15% reduction of the cost of the coating, and great widening of the application range of the coating.

Description

A kind of wilkinite auxiliary agent

Technical field

The present invention relates to a kind of wilkinite auxiliary agent.

Background technology

Coating is a kind of material being coated in coated article surface, and the function of various coating is different, as anti-corrosive type coating, waterproof type coating, insulation compound etc.; Just can reach corresponding effect because coating only need be coated with one deck outside coated article, therefore, coating is used widely in life.

In order to improve the performance of coating, coating may need to add auxiliary agent in allocation process, to make coating have good performance, as: in prior art, bentonite coating is due to its good performance, and is used widely; But bentonite coating refractoriness of the prior art is low, dispersed and splitting resistance is poor, and manufacturing cost is high, brings great limitation to the application of bentonite coating.

Summary of the invention

A kind of wilkinite auxiliary agent provided by the invention, is intended to overcome the deficiency that bentonite coating refractoriness in prior art is low, dispersed and splitting resistance is poor.

In order to solve the problems of the technologies described above, the present invention adopts following technical scheme: a kind of wilkinite auxiliary agent, comprises following component: wilkinite, mica, phosphoric acid, silicon sol, aluminum oxide, magnesium oxide and calcium oxide, and the weight percent of each component is:

Wilkinite: 33% ~ 42%;

Mica: 7% ~ 12%;

Phosphoric acid: 12% ~ 18%;

Silicon sol: 5% ~ 11%;

Aluminum oxide: 10% ~ 12%;

Magnesium oxide: 1% ~ 6%;

Calcium oxide: 2% ~ 8%.

As preferably, a kind of wilkinite auxiliary agent, comprises following component: wilkinite, mica, phosphoric acid, silicon sol, aluminum oxide, magnesium oxide and calcium oxide, and the weight percent of each component is:

Wilkinite: 40%;

Mica: 10%;

Phosphoric acid: 17%;

Silicon sol: 10%;

Aluminum oxide: 10%;

Magnesium oxide: 5%;

Calcium oxide: 8%.

Wilkinite: 33%;

Mica: 12%;

Phosphoric acid: 18%;

Silicon sol: 11%;

Aluminum oxide: 12%;

Magnesium oxide: 6%;

Calcium oxide: 8%.

As preferably, the concentration of described phosphoric acid is 30% ~ 70%.Adopt the phosphoric acid in this concentration ranges, make coating have good performance and low cost of manufacture.

As preferably, the concentration of described phosphoric acid is 60%.The phosphoric acid of this concentration is adopted to make coating have higher cost performance.

A kind of wilkinite auxiliary agent provided by the invention, tool has the following advantages: comprise following component: wilkinite, mica, phosphoric acid, silicon sol, aluminum oxide, magnesium oxide and calcium oxide, and the weight percent of each component is: wilkinite: 33% ~ 42%; Mica: 7% ~ 12%; Phosphoric acid: 12% ~ 18%; Silicon sol: 5% ~ 11%; Aluminum oxide: 10% ~ 12%; Magnesium oxide: 1% ~ 6%; Calcium oxide: 2% ~ 8%; By adopting rational weight ratio between above-mentioned each component and each component, improve the refractoriness of coating, and making coating have good dispersiveness and splitting resistance; Compared with prior art, technical scheme of the present invention makes the refractoriness of coating improve 30% ~ 50%, and dispersed parameter is better than prior art 20% ~ 35%, and splitting resistance parameter is better than prior art 10% ~ 30%; Further, make the cost of coating reduce 10% ~ 15%, greatly broaden the range of application of coating.

Embodiment

Phosphoric acid is one of component of the present invention, and the concentration of phosphoric acid can unrestricted choice, but learns in practice, and when the concentration of phosphoric acid is 30% ~ 70%, coating has good performance and low cost of manufacture; The concentration of phosphoric acid is 60%, and coating has higher cost performance; Certainly, the present invention is in concrete use procedure: it is 10% ~ 20% that auxiliary agent and coating also need with the use of its weight ratio;

Technical scheme of the present invention is further illustrated below by three embodiments:
