Problems solved by technology

[0004] The construction process of wood wax oil requires a long drying time, which will greatly affect the construction process
Simultaneously because wood wax oil is expensive, and film-forming thickness is less, insect-proof effect is limited, therefore develops a kind of wood wax oil of insect-proof quick-drying and becomes the technical problem demanding urgent solution.

Abstract

The invention provides insect-resistant environmentally-friendly wax oil and a preparation method thereof. The insect-resistant environmentally-friendly wax oil is prepared from, by weight, 50-60 parts of vegetable oil, 5-8 parts of carnauba wax, 8-10 parts of a composite insect repellent, 3-6 parts of a cobalt drier, 1-3 parts of a cocatalyst, 1-3 parts of a dispersing agent, 0.5-1.5 parts of benzophenone and 1-3 parts of a coalescing agent. A preparation method of the composite insect repellent comprises the steps that camphor oil and pyrethrin are dissolved in ethyl alcohol, and a solution A is obtained; chitosan is dissolved in a 3 wt% acetic acid aqueous solution, and a chitosan aqueous solution is obtained; the solution A and the chitosan aqueous solution are mixed to be uniform, spray drying is conducted, and the composite insect repellent is obtained. The insect-resistant environmentally-friendly wax oil has the advantages of being rapid in drying, uniform in film formation and naturally resistant to insects, and meanwhile the insect-resistant effect is lasting.

Description

[0001] Technical Field I [0002] The invention belongs to the technical field of coatings, and in particular relates to an insect-proof and environment-friendly wood wax oil and a preparation method thereof. Background technique [0003] With the improvement of economic living standards, people are increasingly concerned about the health of the living environment, and began to seek natural paints with green and environmentally friendly raw materials as the main component to replace traditional paints. Natural paint has begun to be welcomed by some people due to its completely non-toxic, harmless, and healthy natural characteristics. Wood wax oil is composed of natural vegetable oil and vegetable wax as the base material. It does not use any chemical organic solvents and does not produce any harmful gases. Even the vegetable oil and vegetable wax used by major foreign brands are food grade, which is completely healthy and environmentally friendly. Wood wax oil can fully combi...
