Embodiment 1

[0032] Preparation of maleic anhydride oil:

[0033] Put 15 parts of linseed oil and 5 parts of maleic anhydride into a four-neck flask, raise the temperature to 200-220 degrees while stirring and keep it warm for 6-10 hours to pass the test, and take it out of the pot for later use.

Embodiment 2

[0035] Preparation of maleic anhydride oil modified waterborne alkyd resin:

[0036] Put 35 parts of soy oil acid, 5 parts of benzoic acid, 18 parts of pentaerythritol, 18 parts of dimethylolpropionic acid, and 30 parts of phthalic anhydride into the pot, stir and heat up to 170-190 degrees for one hour, then heat up to 200-230 degrees After the viscosity is greater than 380 seconds, add 10 parts of maleic anhydride oil and 20 parts of butyl ether prepared above, stir and keep warm at 135 degrees for one hour, then add 8 parts of triethylamine for neutralization for 30 minutes, then add 35 parts of tap water to obtain maleic anhydride oil modification Waterborne alkyd resin.

Embodiment 3

[0037] Embodiment 3: the environment-friendly alkyd paint prepared by maleic anhydride oil modified waterborne alkyd resin

[0038] Maleic anhydride oil modified water-based alkyd resin 65 parts

[0039] 30 parts of titanium dioxide

[0040] Calcium powder 5 parts

[0041] 65 parts of tap water

[0042] 0.5 parts of water-based bentonite

[0043] 0.3 parts of water-based defoamer

[0044] 0.5 parts of water-based dispersant

[0045] 0.5 parts of water-based leveling agent

[0046] 0.4 parts of environmentally friendly cobalt acetoacetate

[0047] Technological process: Put the above raw materials except the environment-friendly cobalt acetoacetate into a sand mill, grind until the fineness is less than 30 microns, then add the environment-friendly cobalt acetoacetate drier to obtain the maleic anhydride oil-modified water-based alcohol Environmentally friendly alkyd paint prepared from acid resin.

Abstract

The invention relates to a maleic anhydride oil modified aqueous alkyd resin, and an environmentally-friendly paint prepared through using it. The maleic anhydride oil modified aqueous alkyd resin comprises 31-34mass% of soya oil acid or soybean oil or linseed oil, 25-30mass% of phthalic anhydride, 5-8mass% of benzoic acid, 12-15mass% of pentaerythritol, 12-15mass% of dimethylolpropionic acid, 8-11mass% of maleic anhydride oil, 15-25mass% of butyl ether, 5-8mass% of triethylamine, and 15-25mass% of tap water. The invention also discloses an application of an environmentally-friendly acetoacetate-cobalt drier in the aqueous alkyd resin.

Description

technical field [0001] The invention relates to the field of coatings, in particular to the specific performance modification of a maleic anhydride oil-modified water-based alkyd resin and an environmentally friendly paint prepared by using the modified alkyd resin. Background technique [0002] Energy saving and emission reduction is the basic industrial policy of the country, and it is also the future development direction of coatings enterprises, and it is also the core technology and cost advantage for enterprises to win the market. However, the water-based alkyd resins currently on the market in my country have disadvantages such as "thickening", "drying out" and poor gloss and dryness, making them unable to be effectively promoted in the market and difficult to be recognized by users. Contents of the invention [0003] The technical problem to be solved by the present invention is to modify the water-based alkyd resin with maleic anhydride oil and introduce the envir...
