Problems solved by technology

[0002] With the gradual penetration of environmental protection awareness, coupled with the fact that water paints on the market are misleading, consumers have more troubles in the process of purchasing and using them, which affects the later maintenance process and increases the cost of later maintenance.
Moreover, according to the prior art and investigations, the water paint in the prior art has poor weather resistance and water resistance to be improved during use, and it takes a long time in the drying process, and the dryness is slow. It is not weather-resistant and water-resistant, and its co-solvent usage is high, so the VOC content is still high, and the environmental protection performance needs to be improved

Embodiment 1

[0030] An improved water-based acrylic resin, comprising the following components in parts by weight:

[0031] 50 parts of styrene, 30 parts of a mixture of dibutyl maleate and monobutyl maleate, 1 part of initiator, 10 parts of ethylene glycol monobutyl ether, and 5 parts of triethylamine.

[0032] Utilize above-mentioned composition to carry out the preparation of waterborne acrylic acid, concrete process is:

[0033] Close the bottom valve of the clean reactor, feed ethylene glycol monobutyl ether, raise the temperature to 130-140 degrees, put styrene, dibutyl maleate and monobutyl maleate mixture, and initiator TBPB into After the high level tank is stirred, add it dropwise to the reactor, and drop it in two hours, and keep it warm for 1 hour after the drop; add the initiator TBPB, keep it warm for another 1 hour, and measure the conversion rate; when the conversion rate is greater than 95%, Cool to 80°, add triethylamine, cool to 60°, filter and pack to obtain 80% solid-...

Embodiment 2

[0035] An improved water-based acrylic resin, comprising the following components in parts by weight:

[0036] 60 parts of styrene, 50 parts of self-made mixture of dibutyl maleate and monobutyl maleate, 2 parts of initiator, 20 parts of ethylene glycol monobutyl ether, 9 parts of triethylamine.

[0037] When utilizing above-mentioned composition to carry out the preparation of aqueous acrylate, its process is identical with embodiment one.

Embodiment 3

[0039] An improved water-based acrylic resin, comprising the following components in parts by weight:

[0040] 55 parts of styrene, 50 parts of self-made mixture of dibutyl maleate and monobutyl maleate, 1.5 parts of initiator, 15 parts of ethylene glycol monobutyl ether, 7 parts of triethylamine.

[0041] When using the above-mentioned specific proportioning ingredients to prepare water-based acrylic acid, the implementation process is the same as that of Example 1.

Abstract

The invention relates to improved water-based acrylic resin. The improved water-based acrylic resin comprises the following components in parts by weight: 50-60 parts of styrene or styrene partially substituted by acrylate monomers, 30-50 parts of a mixture of self-made dibutyl maleate and monobutyl maleate, 1-2 parts of an initiator, 10-20 parts of ethylene glycol monobutyl ether and 5-9 parts oftriethylamine. The invention further relates to a preparation method of the water-based acrylic resin through the above components. When the water-based acrylic resin is used for preparing varnish, water is directly added, the VOC content of the prepared varnish is lower than 200 g / kg specified by the national standard, environmental protection requirements are met, and cost is low; and thereforethe water-based acrylic resin is widely applied to the technical field of air-drying water-based paint.

Description

technical field [0001] The invention relates to the technical field of self-drying water-based paint, in particular to an improved water-based acrylic resin. Background technique [0002] With the gradual penetration of environmental protection awareness, coupled with the fact that water paints on the market are misleading, consumers have more troubles in the process of purchasing and using them, which affects the later maintenance process and increases the cost of later maintenance. Moreover, according to the prior art and investigations, the water paint in the prior art has poor weather resistance and water resistance to be improved during use, and it takes a long time in the drying process, and the dryness is slow. It is not weather-resistant and water-resistant, and its co-solvent usage is high, so the VOC content is still high, and the environmental protection performance needs to be improved. [0003] Therefore, a kind of water paint that can overcome above-mentioned ...
