preparation example Construction

[0029] The preparation method of the antifreeze protectant is as follows: take konjac powder according to the mass ratio of 1~3:40~60, add hydrochloric acid with a mass fraction of 5%, stir and mix at 45~50°C for 20~30min, add 3~8% of konjac powder β-glucanase, keep warm at 35~45°C for 80~120min, adjust the pH to 6.8~7, inactivate the enzyme, freeze-dry, pulverize and pass through an 80-mesh sieve, collect the sieved particles, and take 40~ Mix 60 parts of sieved granules, 20-30 parts of trehalose, and 20-40 parts of alginate oligosaccharide to obtain the antifreeze protection agent.

[0030]The preparation method of the surfactant is: take coconut oleic acid and add N,N-dimethyl-1,3-propylenediamine according to the mass ratio of 1~3:2~5, stir and mix for 20~30min, add the mass of coconut oleic acid 5~10% ferrocene, put in nitrogen protection, heat up to 140~150°C, stir and mix for 6~10h to get a mixture, take acetone and add water in a mass ratio of 10~20:1~3 and mix to get ...

Abstract

The invention discloses an antifreezing tree trunk whitening agent and a preparation method thereof, and belongs to the technical field of tree whitening agents. An antifreezing active agent for preparation is chelated with calcium and magnesium ions in trees, so that the survival rate of the trees can be improved at a low temperature; hydrophobic C-C long chains on the main chain of a coating additive inhibit shrinkage and expansion of a coating film, and a good coating state is well kept; a surfactant is introduced into the coating film, and an insect-resistant active agent in the whiteningagent is released, so that insect-resistant and anti-microbial functions are synergistic; active substances with insect repelling and sterilizing functions in turmeric, Chinese prickly ash and the like are extracted by alcohol extraction, and insect-resistant and anti-bacterial effects on tree trunks are enhanced; a freezing-resistant active agent is used for reducing the freezing point and storing water inside the tree trunks, so that the tree trunks are prevented from cracking and spalling; and due to response of carbon dioxide generated by respiratory action of the tree trunks, viscosity ofthe coating film is improved, and the overall function of the tree trunk whitening agent is increased. According to the invention, the problems that a formed film of an existing tree trunk coating agent cracks and falls off easily and the insect-resistant and anti-bacterial effects are poor are solved.

Description

technical field [0001] The invention relates to the field of tree whitening agents, in particular to an antifreeze tree trunk whitening agent and a preparation method thereof. Background technique [0002] In urban landscaping, evergreen tree species can add color and vitality to the monotonous autumn and winter seasons. However, in different regions, few evergreen tree species can survive after being transplanted to the north. The main reasons are as follows: 1. The first is freezing damage. Extreme low temperature, extreme daily cooling and extreme continuous cooling events are prone to occur in northern regions. If the extreme low temperature weather lasts for too long, many evergreen tree species will be frostbitten and freeze to death; the second is sunburn For the damage to the trunk, due to the strong daytime sunlight in the northern winter, the temperature of the trunk facing the sun rises, the cells thaw, the temperature drops at night, and then freezes again. "Phe...
