Problems solved by technology

[0003] However, because the traditional epoxy antirust paint is cured and cross-linked at room temperature to form a film, it must be applied at an ambient temperature above 5°C. In addition, it cannot be applied with a thick film, otherwise it will cause problems with the paint film
For example, using the traditional epoxy antirust paint on the market, the curing reaction will stop after construction below 5°C, thus causing various defects of the paint film; in addition, the traditional epoxy antirust paint generally sprays more than 300μm will cause sag problem
These defects have brought great difficulties to the construction, and also limited the use of epoxy antirust paint with good anticorrosion performance on large steel structures.

Abstract

This invention relates to one kind of epoxy antirust paints, discloses one kind of epoxy antirust paints and its making method that can spray by using the thick film and construct under the winter environment. This invention begins with ameliorating the model material, selects the modified amines firming agent and the epoxy group to response, and add preventing flowing hang-aid material, when using the epoxy antirust paint of this invention to paint, not being restricted because the temperature is lower than 5 degree C. In addition, it can do a construction of one-time thick film spray, the wet film thickness can achieve 600 mu m, after uniformly mixing the Group A and B, it has excellent film-forming character and good storage stability under the normal or low temperature (above -10 degree ).

Description

technical field [0001] The invention relates to an epoxy antirust paint, in particular to an epoxy antirust paint capable of thick-film spraying and suitable for construction in winter environments and a preparation method thereof. Background technique [0002] With the continuous development of the national economy and basic construction, national key projects and large-scale projects have higher and higher requirements for anti-corrosion. Large-scale steel equipment and components have higher requirements for coatings, which require coatings to have excellent anti-corrosion properties. Performance, but also must have good construction and adaptability. Epoxy antirust paints are known to have good chemical and corrosion resistance. [0003] However, since the traditional epoxy antirust paint is cured and cross-linked at room temperature to form a film, it must be applied at an ambient temperature above 5°C. In addition, it cannot be applied with a thick film, otherwise it ...
