Plant sterilization and parasite expelling function type water-borne wood paint and preparation method thereof

Abstract

The invention discloses plant sterilization and parasite expelling function type water-borne wood paint and a preparation method thereof. The plant sterilization and parasite expelling function type water-borne wood paint is prepared from the following components in parts by weight: 60 to 85 parts of aliphatic modified polyurethane dispersoid, 0.3 to 0.8 part of plant compound nano sterilization powder, 1 to 3 parts of hardening resin, 7 to 12 parts of water, 1 to 3 parts of wax emulsion and 4 to 12 parts of other auxiliary agents. The physicochemical technical indexes of the water-borne wood paint exceed those of oily wood paint; the plant compound nano sterilization powder can be prepared by treating cheap and easy-to-obtain raw materials including purslane, pine needles, cinnamomum camphora, platycladus orientalis, deodar and the like through an infrared dehydration technology and a nano production technology. The plant sterilization and parasite expelling function type water-borne wood paint belongs to a green, environment-friendly and healthy sterilization material, is toxin-free and harmless to human bodies and has lasting and efficient effects. The water-borne wood paint has low cost and efficient and lasting effects in sterilizing, inhibiting bacteria, preventing mildew and expelling parasites.

Description

technical field [0001] The invention relates to the technical field of water-based wood lacquer, and particularly discloses a water-based wood lacquer with plant bactericidal and insect repellent functions and a preparation method thereof. Background technique [0002] Viruses and bacteria exist everywhere in our living environment, which pose a threat to human health; in addition, pests such as mosquitoes, flies, cockroaches, fleas, bedbugs and mites can spread diseases and affect people's health. In this regard, humans are also constantly developing sterilization and deworming technology. For example, there is a technical branch of antibacterial coatings in the coatings industry. [0003] Antibacterial agents in antibacterial polyurethane materials are usually inorganic antibacterial agents such as silver ions, organic antibacterial agents such as quaternary ammonium antibacterial agents, natural antibacterial agents such as chitosan and its derivatives, sorbic acid, etc....

AI Technical Summary

Problems solved by technology

Quaternary ammonium salt antibacterial agents also have certain toxicity, while chitosan and its derivatives, sorbic acid, etc. are not strong enough to kill bacteria, so it is not recommended to add them to coatings

[0004] Patent CN104194514A uses nano-silver aqueous solution, plants such as tea, scutellaria baicalensis, Sophora japonica extracts, styrene-acrylic emulsion, etc. to make anti-mildew and bactericidal coatings. However, as mentioned earlier, nano-silver may cause a certain degree of bodily harm

CN104449279A uses modified water-based vegetable oil alkyd resin and phenolic resin as film-forming resins, adds natural antibacterial and acaricidal components such as nano-bamboo fiber, aloe oil and mugwort oil, and finally makes water-based coatings for glass doors, but aloe oil, mugwort oil, etc. Easily volatile, the antibacterial ability of the coating will not last

The waterproof antibacterial coating disclosed by CN104004427A contains polyacrylate emulsion, polyurethane emulsion, antibacterial agent such as isothiazolinones, benzisothiazolinones, formaldehyde releasing agent, etc., and the safety and environmental protection of this coating is insufficient

The insect repelling ingredients disclosed in CN104017405A include tuberose, lavender, pitcher plant, geranium, seven lixiang, marigold, fly plum, etc., but the composition of the wood paint is not specified, and the wood paint has almost no bactericidal effect. antibacterial properties
