[0033] Preparation of emulsion:

[0034] Methyl methacrylate, butyl acrylate, and acrylic acid were pre-mixed, and the mixed solution was poured into a 50ml constant pressure dropping funnel, stirred and mixed for later use at a speed of 300 rpm, and named as monomer a liquid.

[0035] Ammonium persulfate, diacetone acrylamide, water, stir until dissolved (diacetone acrylamide is difficult to completely dissolve), pour it into a 50ml constant pressure dropping funnel, and name the initiator dropping solution b.

Embodiment 5

[0045] The glossiness of embodiment 5 gained emulsion is the highest, and its performance index is as follows:

[0046]

[0047] It can be seen from the above table that the emulsion has high solid content, good stability, and high gloss, reaching the performance index of similar products in the market. At the same time, the test shows that the emulsion has excellent storage stability, and no delamination occurs when it is stored at room temperature for six months. Gloss measurement is based on GB / T97541988 Paint and varnish Determination of the sum of specular gloss of paint films without metallic pigments.

Abstract

Provided is a highlight acrylic ester emulsion for pigments. The emulsion is characterized by comprising the following ingredients: methyl methacrylate, butyl acrylate, acrylic acid, diacetone-acryloamide, dehydrated sorbitol oleate polyoxyethylene ether sulpho, disodium succinate and the like. The invention also discloses a preparation method for the emulsion. Compared with the prior art, the emulsion is advantageous in that the highlight performance is reflected effectively through addition of diacetone-acryloamide and dehydrated sorbitol oleate polyoxyethylene ether sulpho, disodium succinate in the emulsion system.

Description

technical field [0001] The invention relates to an emulsion for pigment. The invention also relates to a method for preparing the emulsion. Background technique [0002] In the 1940s, American painters used acrylic emulsions to prepare and paint pigments with the advantages of light resistance, light resistance and water erosion resistance, and acrylic paints were born. The quality of acrylic paint will have a great impact on the performance of painting techniques, and it is also one of the prerequisites for determining the life span of paintings. Therefore, the performance and selection of acrylic emulsion largely determine the comprehensive performance of acrylic paint. [0003] In recent years, researchers have carried out a lot of work in the field of emulsion polymerization, but relatively little research has been done in the field of acrylic emulsions for painting, so that most of the existing polymer emulsions cannot be well applied in the production of acrylic pain...
