[0038] Concrete preparation process is as follows:

[0039] Step A. Preparation of epoxy ester base resin: E42 epoxy resin, linolenic acid, methacrylic acid, zinc oxide, and xylene are heated in a three-necked flask, heated to 180°C and reacted until the acid value is less than 10mgKOH / g, then stop Heating, pumping out reflux xylene, adding hydroquinone and stirring evenly.

[0040] Step B, preparation of functional monomer resin mixture: styrene, methyl methacrylate, acrylic acid, butyl acrylate, isobornyl methacrylate, methacryloxypropyl trimethoxysilane, vinyl trimethoxysilane Ethoxysilane and epoxy ester base resin are mixed and stirred well.

[0041] Step C. Preparation of pre-emulsion: Dissolve 90% of YX-011 emulsifier in one-third of deionized water and stir evenly. Slowly ...

Embodiment 2

[0045]The amount of raw materials is shown in Table 1. The vinyl triethoxysilane is GF56 from Wacker, Germany; the methacryloxypropyl trimethoxysilane is Silquest A-174 from Momentive, USA; the emulsifier is OP from Dow, USA -10.

[0046] Concrete preparation process is as follows:

[0047] Step A. Preparation of epoxy ester base resin: E42 epoxy resin, linolenic acid, methacrylic acid, zinc oxide, and xylene are heated in a three-necked flask, heated to 180°C and reacted until the acid value is less than 10mgKOH / g, then stop Heating, pumping out reflux xylene, adding hydroquinone and stirring evenly.

[0048] Step B, preparation of functional monomer resin mixture: styrene, methyl methacrylate, acrylic acid, butyl acrylate, isobornyl methacrylate, methacryloxypropyl trimethoxysilane, vinyl trimethoxysilane Ethoxysilane and epoxy ester base resin are mixed and stirred well.

Abstract

The invention discloses a water-borne acrylic acid modified epoxy ester emulsion containing silicon and a preparation method of the water-borne acrylic acid modified epoxy ester emulsion, belongs to the field of chemical industry, and aims to solve the problems that existing water-borne products are low in hardness, poor in medium resistance, poor in surface anti-pollution capacity and instable instorage. The emulsion is prepared by, by mass, 8-10 parts of linoleic acid, 1-5 parts of E42 epoxy resin, 0.5-3 parts of methacrylic acid, 1-1.5 parts of xylene, 0.01-0.1 part of zinc oxide, 0.01-0.1part of hydroquinone, 5-10 parts of methyl methacrylate, 15-20 parts of butyl acrylate, 0.3-0.5 part of acrylic acid, 0.5-0.8 part of isobornyl methacrylate, 0.2-0.5 part of methacryloxy propyl trimethoxyl silane, 0.2-0.5 part of vinyl triethoxysilane, 1-2 parts of emulsifier, 45-50 parts of deionized water, 0.5-1 part of ammonium persulfate and 0.3-0.5 part of sodium bicarbonate. The prepared emulsion serving as coating has the advantages that the VOC content of the emulsion is lowered greatly, environment pollution is reduced, and various performance of the emulsion is increased; the emulsion is capable of meeting multiple national mandatory standards and technical requirements and low in cost.

Description

technical field [0001] The invention belongs to the field of chemical industry, and in particular relates to a silicon-containing water-based acrylic modified epoxy ester emulsion. Background technique [0002] Domestic industrial coatings are still dominated by solvent-based coatings. The biggest disadvantages of this type of coatings are that they pollute the environment, are flammable, and are harmful to the human body. There is still a gap between my country's water-based coatings and developed countries, and high-performance water-based resins still rely on imports. At present, the VOC content of coatings in my country is getting lower and lower, so water-based coatings are the general trend, and emulsion resins are new products that meet environmental protection requirements because of their lower VOC content. Contents of the invention [0003] The purpose of the present invention is to provide a silicon-containing water-based acrylic modified epoxy ester emulsion t...
