Problems solved by technology

This dispersant is E10P modified polyester resin, and the polyester resin color and luster of this preparation method is darker, and color and luster is usually in 200-300, is not suitable for being used in the paint with higher color requirement; In addition, on the main chain of polyester resin The stability of the ester bond is not good, which will greatly affect the resistance of the paint film (including alkali and water resistance, color and gloss retention)

preparation example Construction

[0040] In a preferred example, the preparation method of the polyester modified acrylic resin comprises the following steps:

[0041] Mix lauric acid, isononanoic acid, isooctanoic acid, NPG, TMP, terephthalic anhydride, hexahydrophthalic anhydride, tetrahydrophthalic anhydride, butenedioic anhydride and heat up to 120°C. After dehydration, heat up to 225 within 4 hours. Keep at ℃ for 0.5 hours. When the acid value is less than 30mgKOH / g, add xylene to reflux. When the acid value is less than 6.5-10.5mgKOH / g and the viscosity is Z1-Z3, a polyester intermediate is obtained;

[0042] Heat the polyester intermediate and solvent to 150-160°C under nitrogen protection, add the mixture of acrylate monomer and 90wt% initiator dropwise within 3 hours, keep it warm for 1 hour, and then add the remaining initiator , kept warm for 3 hours, and diluted to a solid content of 70%, to obtain the polyester-modified acrylic resin.

[0043]The polyester-modified acrylic resin structure reduces...

Embodiment 1

[0066] Include in the highly concentrated universal environment-friendly color paste raw material of the present embodiment: 31kg mass percent is 70% polyester modified acrylic resin A, 9.5kg propylene glycol methyl ether acetate, 5kg S-100 solvent, iron yellow 48kg, polyurethane Dispersant 6.5kg.

[0067] Its preparation method is: (1) the polyester modified acrylic resin A of 31kg, 6.5kg polyurethane dispersant, 9.025kg propylene glycol methyl ether acetate, 4.75kg S-100 solvent is added in the container of suitable size, stirs (400 -600rpm) for 10-15 minutes; (2) Add 48kg of PY42 iron yellow pigment while stirring, after adding the pigment, stir (400-600rpm) for 10-15 minutes; (3) Add the remaining solvent propylene glycol methyl along the container wall while stirring Ether acetate and S-100 solvent, continue to stir for 30 minutes until uniform; (4) Start grinding and dispersing on the designated sand mill until the fineness meets the requirements;

[0068] The above-men...

Embodiment 2-5

[0070] The components of the highly concentrated universal environment-friendly color paste of each embodiment are shown in Table 1, the preparation method of each embodiment is basically the same as that of Example 1, and the technical indicators of the prepared coating are shown in Table 2.

[0071] The formula composition of table 1 embodiment 2-5 environment-friendly color paste

[0072]

[0073]

[0074] Table 2 embodiment 1-5 gained color paste performance

[0075]

[0076] The above-mentioned high-concentration universal colorants are used to replace the original low-concentration colorants of several product systems to prepare colored paints, and the key performance changes before and after the replacement are investigated.

Abstract

The invention discloses a high-concentration general color paste which comprises the following components in parts by weight: 30-60 parts of polyester modified acrylic resin, 3-15 parts of a dispersant, 0-1 part of an optional dispersing aid, 10-50 parts of a pigment, and 10-50 parts of an organic solvent. The color paste is universally used in various general industrial coatings, and the obtainedcoating is good in wettability, moderate in viscosity, environment-friendly and good in color development property and stability. The invention also discloses a preparation method and application ofthe color paste.

Description

technical field [0001] The invention relates to the field of general industrial coatings. More specifically, it relates to a high-concentration universal color paste and its preparation method and application. Background technique [0002] With the development of the domestic economy, the paint industry has entered a period of rapid development. In the field of general industrial coatings, whether it involves light machine coatings or heavy machine coatings, application clients have put forward higher and higher requirements for durability and aesthetics. Polymer resins and pigments are important components of coatings. Polymer resins provide protection (meeting various resistance requirements) and decoration (meeting gloss and fullness requirements) on the surface of various workpieces; pigments endow the paint film with colorful Excellent color, cover the defects of the substrate, beautify the appearance, and help to improve the resistance of the coating. [0003] There...
