Antiseptic primer for medium gray indoor steel structure and preparation method thereof

Abstract

The invention provides antiseptic primer for a medium gray indoor steel structure and a preparation method thereof. The primer is prepared from the following components in parts by weight: 25-30 parts of home-made 750# resin, 5-10 parts of chlorinated rubber solutions, 0.1-0.5 part of carbon black, 2-5 parts of titanium dioxides ( A type ), 15-25 parts of titanium powder, 0.01-0.05 part of phthalocyanine blue( BS type ), 10-20 parts of ground calcium carbonate, 5-10 parts of zinc phosphate, 0.1-0.5 part of organobentonite, 0.1-0.3 part of 1% silicone oil xylene solutions, 0.3-0.8 part of composite drier CY320, 20-25 parts of functional addition agents and 10-15 parts of mixed solvent. The antiseptic primer provided by the invention has the advantages that the air drying is quick, the adhesive force of primer films is strong, the acid resistance is strong, the cost is low, the use is quick and convenient, the heating and the drying are not required, the coating time and the expense are reduced, and the energy is saved. For the antiseptic primer, waste dacron materials are used, so that the waste dacron materials are changed into things of value and circularly utilized, and harm to environment caused by the waste materials is eliminated.

Description

Technical field: [0001] The invention relates to the field of paints, in particular to a medium gray indoor steel structure anticorrosion primer and a preparation method thereof. Background technique: [0002] With the increasing rise of steel structure workshops, most of them have replaced the traditional cement and brick structures. At the same time, protective coatings on steel structures have also emerged. It requires not only anti-corrosion performance, but also fire protection. At the same time, the drying of the coating Time is very fast, so a new 750# resin was developed, the introduction of petroleum resin and terephthalic acid improved the drying time of "polyester modified alkyd resin" in the prior art, especially its shortcoming of impermeable drying , the addition of "chlorinated rubber" in the finished paint has greatly improved the drying time of the coating film, and has greatly improved acid resistance, alkali resistance, and salt spray resistance (corrosion...

Problems solved by technology

[0002] With the increasing rise of steel structure workshops, most of them have replaced the traditional cement and brick structures. At the same time, protective coatings on steel structures have also emerged. It requires not only anti-corrosion performance, but also fire protection. At the same time, the drying of the coating Time is very fast, so a new 750# resin was developed, the introduction of petroleum resin and terephthalic acid improved the drying time of "polyester modified alkyd resin" in the prior art, especially its shortcoming of impermeable drying , the addition of "chlorinated rubber" in the finished paint has greatly improved the drying time of the coating film, and has greatly improved acid resistance, alkali resistance, and salt spray resistance (corrosion performance). Currently, products in this market use "Epoxy" series, their problems are: single-component anti-corrosion performance is not good, two-component "curing agent" is very inconvenient to use, the construction time is too long, and the cost is high, 750# resin It takes into account the reuse of waste materials and eliminates pollution; because the finished paint has an extremely fast drying time, it reduces the coating man-hours and costs, and saves energy; so the finished anti-corrosion paint has a good advantage in terms of cost performance
