Example Embodiment

[0039] Example 1

[0040] The present invention provides a method for preparing an aqueous alkyme-acrylic acid hybrid resin, comprising the steps of:

[0041] (1) Preparation of the base alkyd resin, the composition of the feedstock, such as Table 1.

[0042] The preparation method is: the raw material is added to the clean reaction kettle, and the temperature is warmed to 180 ° C, constant temperature 1 h, and the condensed water is collected from the xylene. Continue to warm to 225 ° C, constant temperature to the raw material to continue to heat up to 245 ° C, to less than 10 mgkOH / g, cool down, dilute, and obtain the base alkyd resin.

Abstract

The invention belongs to the technical field of high-performance environment-friendly coatings, and discloses water-based alkyd acrylic hybrid resin and a preparation method thereof.The hybrid resin is prepared from fatty acid modified acrylic prepolymer, basic alkyd resin, a solvent, a neutralizer and water. The preparation method comprises the following steps: carrying out local polycondensation on the fatty acid modified acrylic prepolymer and the basic alkyd resin, and neutralizing and dispersing. A coating prepared from the water-based alkyd acrylic hybrid resin has excellent water resistance, dryness, hardness, heat storage capacity and the like, water-based paint prepared from the resin combines excellent wettability and pigment and filler bearing capacity of alkyd resin and acrylic acid, and the gloss can reach 85-90; The coating is suitable for the large-scale civil paint field and the industrial paint field.

Description

technical field [0001] The invention relates to the technical field of high-performance environmental protection coatings, in particular to a water-based alkyd-acrylic hybrid resin and a preparation method thereof. Background technique [0002] With the development of industry, the problem of environmental pollution is more and more troubled by human beings, so the development of environmentally friendly coatings is a major trend. The fundamental way to solve the problem of environmental pollution by coatings is to develop solvent-free coatings, water-based coatings, powder coatings and high-solid coatings. With the enhancement of people's awareness of environmental protection and the increasingly stringent environmental protection regulations, water-based coatings have become one of the main development directions of environmentally friendly coatings. Water-based coatings have reduced environmental pollution because all or most of them have replaced organic solvents with wa...
