Problems solved by technology

At present, there have been a lot of related research and work in progress, but most of the work is concentrated on alkyd resin, alkyd modified polyurethane, or the use of extremely special raw materials from renewable sources. The process is cumbersome and complicated, and the application fields and Raw material costs are severely limited
In the application of water-based acrylic acid, although there are related reports, there are still great defects due to technical reasons. If all acrylic acid monomers from biorenewable sources are used, raw material purification, raw material sources, and cost control will all have big problems.

Abstract

The invention discloses a preparation method of novel biological matrix non-soap type core-shell structure water-based acrylic acid emulsion. The preparation method comprises the following steps: 1) adding fatty acid, monobasic acid and polyol with natural source according to a certain proportion to prepare an alcohol acid intermediate; 2) adding a certain amount of polybasic acid and anhydride into the alcohol acid intermediate prepared in the step 1 according to a certain proportion and dissolving into water to prepare an alcohol acid aqueous solution; and 3) adding an acrylic acid comonomerin the alcohol acid aqueous solution in the step 2 at a time or in batches, adding an initiator, a reducing agent, a catalyst, a molecular weight regulator, reacting at 30 to 95 DEG C for 10 to 90 minutes, adding aids such as a crosslinking agent, a sterilizing agent, preservative, a stabilizer and a defoaming agent as required, and finally obtaining the novel biological matrix non-soap type core-shell structure water-based acrylic acid emulsion. The emulsion has the advantages of environmental friendliness, reproducible raw materials, low cost, high drying speed, wide and adjustable film-forming temperature and hardness and the like, and is favorable for application and popularization of biological matrix concept products.

Description

Technical field: [0001] The invention relates to an aqueous acrylic emulsion, which is applied to the field of coatings. In particular, it relates to a preparation method of a biological matrix soap-free core-shell structure aqueous acrylic emulsion. technical background: [0002] In recent years, due to the pressure of environmental protection, there has been a growing call for the use of renewable resources to replace traditional petroleum-based products, and there has been increasing interest in products that use biological matrices in polymers. Biomatrix raw materials are derived from renewable sources. Agricultural, forest and marine resources. For bio-based polymers, there has been no unified definition and description. For coatings, the ASTM d6866 standard implemented by the USDA Biomass Priority Program is a more standardized certification and classification method. It defines the categories of biological priority coatings as follows: [0003] % cont...
