[0023] A preparation method of straw paint, comprising the steps of:

[0024] A. Stir and dissolve 10-20g straw raw materials in 100g water, stir and heat to 80°C;

[0025] B. Add 0.1-0.15g sodium dithionite, 0.4-0.6gNaHCO 3 , 0.1-0.2gNa 2 CO 3 and emulsifier, the emulsifier is formed by mixing 0.8-0.9g of nonionic surfactant x405 and 1-2g of water, and stirring for 10 minutes to obtain a mixed solution;

[0026] C. Add an initiator to the mixed solution. The initiator is mixed with 1g of potassium peroxodisulfate and 18-19g of water. First add 50% of the volume of the initiator, drop it within 10-15 minutes, and continue to stir for 15 minutes. ;

[0027] D. Add the reaction monomer to the mixed solution of step C, the reaction monomer is formed by mixing 37-38g of butyl acrylate and 31-32g of methyl methacrylate, first add the reaction monomer with a volume of 10% dropwise for 10-15 minutes After the internal dropwise addition was completed, the stirring reaction was co...

Abstract

The invention relates to the technical field of biomass paint, and especially relates to a straw paint preparation method. The method uses agriculture waste such as straw as a raw material, a novel processing technology is employed, and a straw emulsion is prepared. Compared with a same model emulsion on the market, the cost of the straw emulsion is reduced by about 30%, the straw emulsion can beuse for processing the straw paint, and can be used for preparing a base material for various adhesives; so that the straw paint has wide market prospect and large application value. Compared with a same model paint on the market, the cost of the straw paint is reduced by about 30%, and the straw paint has the advantages of environmental friendliness and excellent performance.

Description

technical field [0001] The invention relates to the technical field of biomass coatings, in particular to a preparation method of straw coatings. Background technique [0002] China's annual output of crop straw is about 700 million tons, ranking first in the world. Straw resource utilization technology presents diversified development. Such as returning straw to the field, making organic fertilizer, straw gasification and briquetting fuel, animal feed, as raw material for paper and textile industries, and cultivating edible fungus with straw, etc. However, there is still a considerable gap compared with some western countries. A considerable part of crop straw is still discarded in fields and ditches, or burned. [0003] From the amount of straw recycling, it can be seen that most of the straw is used as fuel and fertilizer, the actual recycling rate is low, and the scope of recycling is limited, making straw recycling unable to meet market demand.
