AI Technical Summary

Problems solved by technology

The performance of the coating is mainly derived from the coating. The existing polyurethane flame retardant coating either has no flame retardant function or has a poor flame retardant effect. In order to achieve a better flame retardant effect, more than 30% of the flame retardant is generally added to it. The addition of a large amount of flame retardants will seriously affect other basic properties of the coating. For example, when the coating is scratched by external force, the basic properties of the polyurethane coating will be destroyed, and the waterproof, anti-fog and flame retardant will be lost. effect

[0085] Preparation of Experimental Example 1 Coating

[0086] The coatings provided by Examples 1-7 and Comparative Examples 1-9 are used to prepare flame-retardant and scratch-resistant coatings, and the preparation method is as follows:

[0087] S1. Under nitrogen atmosphere, mix 30% of total isocyanate, flame retardant polyester polyol, PDMS, adhesion promoter, acrylate modified nano silica, flame retardant, catalyst, chain extender, solvent, Mix other additives and react at 55°C and 800rpm for 3 hours; lower the temperature to 30°C and use it as material A of the coating; use the remaining isocyanate as material B;

[0088] S2. Mix material A and material B, and disperse and react at 800rpm for 30 minutes to obtain a coating;

[0089] S3. Coating the paint on the PET film, baking at 60° C. for 10 minutes, and then annealing at 50° C. for 3 days to obtain the flame-retardant and scratch-resistant coating.

[0090] Experimental Example 2 Coating Performance Test

[0091] 1. Test method

[0092] (1) The flame retardancy of the 16 coatings prepared in Experimental Example 1 was tested using the test method of the international standard 94-VTM.

[0093] (2) The 16 coatings prepared in Experimental Example 1 were scraped back and forth on the coating surface for 30 times with a copper brush, and the scratches on the coating surface were observed through an AFM atomic force microscope.

Abstract

The invention provides a flame-retardant and wear-resistant coating and application thereof in preparation of a flame-retardant and scratch-resistant coating. The flame-retardant and wear-resistant coating is prepared from 200 to 300 parts of isocyanate, 80 to 150 parts of flame-retardant polyester polyol, 10 to 70 parts of PDMS (Polydimethylsiloxane), 5 to 8 parts of an adhesion promoter, 15 to 30 parts of acrylate modified nano silicon dioxide, 5 to 30 parts of a flame retardant, 10 to 20 parts of a catalyst, 5 to 30 parts of a chain extender, 500 to 700 parts of a solvent and 15 to 30 parts of other auxiliaries. A coating material prepared from the coating has the characteristics of high flame retardance and excellent scratch resistance, is easy for industrial production, and is suitable for the field of preparation of PET wooden furniture high-end protective films, insulating electric adhesive tapes and wooden door protective films.

Description

technical field [0001] The invention belongs to the technical field of coating preparation, and in particular relates to a flame-retardant and wear-resistant coating and its application in preparing a flame-retardant and scratch-resistant coating. Background technique [0002] Polyurethane coatings appeared in the 1940s and have developed greatly so far. They have been widely used in national defense, infrastructure, petroleum, chemical industry, anti-corrosion, electrical insulation, wood coating, etc., and new varieties continue to emerge. Polyurethane coatings have excellent comprehensive properties, such as mechanical properties, chemical resistance, oil resistance, abrasion resistance, durability and beautiful decorative properties, etc. The performance of the coating is mainly derived from the coating. The existing polyurethane flame retardant coating either has no flame retardant function or has a poor flame retardant effect. In order to achieve a better flame retarda...
