Problems solved by technology

[0003] Currently used antibacterial coatings, anti-mold coatings, anti-fouling coatings, etc. basically rely on the dissolution and release of various active substances (antibacterial, anti-mold or anti-fouling) used to function, thus causing the following problems : 1. Pollution of the environment; 2. Great threat to human safety; 3. Long-term effectiveness is difficult to be guaranteed, etc.
[0007] However, so far, domestic and foreign coating technologies all use dissolution coatings to achieve functional effects (antibacterial, antifungal or antifouling) by releasing (antibacterial, antifungal or antifouling) active substances, so there is a large limitation

Embodiment 1

[0070] Take 76g of 1,8-octanediamine and 61g of 1,6-hexamethylenediamine, and add them to two 500mL three-neck flasks respectively, then add 48g of guanidine hydrochloride to each of the two flasks, and stir and Raise the temperature to 120°C, react for 4 hours, then combine the materials in the two flasks into one, and gradually raise the temperature to 170°C to continue the reaction for 1.5 hours, then add 54g of laurylamine, continue to react for 2 hours and then pour it out while it is hot. After cooling, the functional guanidine oligomer is obtained. Take 0.941 g of the guanidine oligomer and dissolve it in 5.23 g of methanol solvent (6.17 g in total) to obtain a solution of the functional guanidine oligomer.

[0071] The second step is similar to Comparative Example 1, using St, MMA, BA, and GMA as mixed monomers, wherein h, l, m, and k are respectively: 0.24, 0.165, 0.066, and 0.002. The mixed monomer was poured into a three-necked flask placed in a water bath together...

Embodiment 2

[0074] Take 76g of 1,8-octanediamine and 61g of 1,6-hexamethylenediamine, and add them to two 500mL three-necked flasks respectively, then add 48g of guanidine hydrochloride to each of the two flasks, and stir and Raise the temperature to 120°C, react for 4 hours, then combine the materials in the two flasks into one, and gradually raise the temperature to 170°C to continue the reaction for 1.5 hours, then add 54g of laurylamine, continue to react for 2 hours and then pour it out while it is hot. After cooling, the functional guanidine oligomer is obtained. 16.1 g of the guanidine oligomer was taken and dissolved in 89.44 g of dimethyl sulfoxide solvent (105.44 g in total) to obtain a solution of the functional guanidine oligomer.

[0075] The second step is similar to Comparative Example 1, using St, MMA, BA, and GMA as mixed monomers, wherein h, l, m, and k are respectively: 0.24, 0.165, 0.066, and 0.002. The mixed monomer was poured into a three-necked flask placed in a wa...

Embodiment 3

[0078] Get 97g of α, ω-tetraethylene glycol diamine and 44g of 1,4-butylene diamine, add respectively in two 500mL three-necked flasks, then respectively add 48g of guanidine hydrochloride in the two flasks respectively, under nitrogen atmosphere Under protection, stir and heat up to 120°C, react for 4 hours, then combine the materials in the two flasks into one, and gradually heat up to 170°C to continue the reaction for 1.5 hours, then add 87g of palmitamine, and continue the reaction for 2 hours Pour it out while it is hot, and get the functional guanidine oligomer after cooling. Take 1.049 g of the guanidine oligomer and dissolve it in 5.828 g of dimethylformamide solvent (6.877 g in total) to obtain a solution of the functional guanidine oligomer.

[0079] The second step is similar to Comparative Example 1, using St, MMA, BA, and GMA as mixed monomers, wherein h, l, m, and k are respectively: 0.24, 0.165, 0.066, and 0.002. The mixed monomer was poured into a three-necke...

Abstract

The invention relates to an intrinsic functional coating and preparation and application thereof. Compared with the prior art, according to a preparation method, different kinds of resin monomers arecopolymerized into matrix resin, then the matrix resin and a guanidine oligomer are subjected to chemical bonding, and the intrinsic harmful microorganism-resistance functional coating without dissolution is obtained. According to needs of different application fields, different auxiliary additives such as an antioxygen and an ultraviolet screening agent can be added to directly serve as intrinsicfunctional additives of an intrinsic oil-soluble coating or an oil-soluble coating; a universal intrinsic functional additive for an intrinsic emulsion coating or an emulsion coating for interior andexterior walls can also be prepared through concentration and emulsification. All the application modes have the advantages of no dissolution and quite high safety, and the intrinsic functional coating has almost permanent functions of resisting viruses, bacteria, superbacteria, mould, fungi, algae and mites and preventing adhesion of freshwater and marine organisms, and has a quite wide application prospect.

Description

technical field [0001] The invention belongs to the technical field of coatings, and relates to a non-dissolution intrinsic and anti-harmful microorganism functional coating and its preparation, and its application in daily necessities, medical and sanitary materials, chemical products, construction, breeding cages, ships, marine equipment, etc. field applications. Background technique [0002] With the rapid development of modern industry, human beings pay more and more attention to environmental pollution, and the degree of concern for their own health is also increasing, thus increasing the urgent demand for functional environmental protection coatings, such as heat insulation coatings, high temperature resistance, Corrosion coatings, high temperature insulation coatings, flame retardant coatings, wear-resistant coatings, anti-icing coatings, anti-pollution coatings, etc. [0003] Currently used antibacterial coatings, anti-mold coatings, anti-fouling coatings, etc. basi...
