Problems solved by technology

[0002] The paint is mainly composed of alkyd resin, which is the largest type of paint in China at present. It has the advantages of cheap price, simple construction, low requirements on the construction environment, plump and hard coating film, good durability and weather resistance, decorative and The protection is better, etc., but the existing alkyd paint will have sediment and bleeding after a period of storage, which will affect the normal use of alkyd paint

Embodiment approach 1

[0010] Take 100 kg of water and add it to the mixer, add 0.3 kg of hydroxypropyl methylcellulose into the water, stir slowly and quickly to dissolve it completely, then add 1.2 kg of OP-10, and stir for 25 minutes. become.

Embodiment approach 2

[0012] Take 100 kg of water and add it to the mixer, add 0.6 kg of hydroxypropyl methylcellulose into the water, stir slowly and quickly to dissolve it completely, then add 1.5 kg of OP-10, and stir for 25 minutes. become.

Embodiment approach 3

[0014] Take 100 kg of water and add it to the mixer, add 0.5 kg of hydroxypropyl methylcellulose into the water, stir slowly and quickly to dissolve it completely, then add 1.5 kg of OP-10, and stir for 25 minutes. become.

[0015] Instructions

[0016] Add 100 kg of finished alkyd paint into the mixer, then start the mixer, slowly add 5-10 kg of additives into the paint and stir for 25 minutes to complete the finished product. Good-quality paint can be increased in an appropriate amount, and poor-quality paint can be moderately increased, but the weight of additives added to 100 kg of finished alkyd paint should not be less than 7 kg.

[0017] Test shows, common alkyd paint, in depositing 10 months, deposit and bleeding occur in paint, and the alkyd paint that adds anti-sedimentation additive of alkyd paint of the present invention does not have this phenomenon, and does not store alkyd paint Same effect.

Abstract

The invention discloses a paint anti-settling additive and a production method thereof. The paint anti-settling additive and the production method thereof are characterized in that the additive is composed of adding hydroxypropyl methyl cellulose and OP-10 to water, wherein in 100 kg of water, the weight of the added hydroxypropyl methyl cellulose is 0.3-0.6 kg, and the weight of the added OP-10 is 1.1-1.5 kg. Since the hydroxypropyl methyl cellulose itself has an anti-settling effect, the OP-10 is added to a hydroxypropyl methyl cellulose solution, and since the OP-10 is an emulsifier to makethe hydroxypropyl methyl cellulose solution well combined with alkyd paint, so that the alkyd paint to which the additive is added has an anti-precipitation effect, and since the cost of the additiveis lower than the cost of the alkyd paint, and so, the cost of the alkyd paint to which the additive is added is less than that of the alkyd paint, thereby reducing the usage cost.

Description

technical field [0001] The invention relates to a paint anti-settling additive and a production method thereof. Background technique [0002] The paint is mainly composed of alkyd resin, which is the largest type of paint in China at present. It has the advantages of cheap price, simple construction, low requirements on the construction environment, plump and hard coating film, good durability and weather resistance, decorative and The advantages such as protection are all relatively good, but, existing alkyd paint can have deposit and bleeding phenomenon after storing for a period of time, affects the normal use of alkyd paint. Contents of the invention [0003] Aiming at the shortcomings of the above-mentioned prior art, the object of the present invention is to provide paint anti-sedimentation additives and a production method thereof. This additive makes the use effect of alkyd paints better and also reduces the cost of alkyd paints. [0004] The technical scheme adop...
