[0022] An oily red paste formula (weight): oily permanent red paste.

[0023] The components and weight ratio of oily permanent red paste are as follows:

[0024] 55 kg of alkyd resin, 15 kg of propylene glycol methyl ether acetate, 0.1 kg of anti-skinning agent, 6 kg of dispersant, 0.5 kg of synergistic dispersant, 18 kg of permanent red powder, 6 kg of butyl acetate.

[0025] Preparation:

[0026] (1) The conventional physical mixing method is the first, that is, various materials are mixed in proportion and dispersed at a high speed of 2000rpm to prepare a paste-like product.

[0027] (2) Then pass through a sand mill to a fineness of 15 μm to obtain 100 kg of qualified products.

Embodiment 3

[0029] An oily red paste formula (weight): oily permanent red paste.

[0030] The components and weight ratio of oily permanent red paste are as follows:

[0031] 60 kg of alkyd resin, 15 kg of propylene glycol methyl ether acetate, 0.1 kg of anti-skinning agent, 6 kg of dispersant, 1.9 kg of synergistic dispersant, 11 kg of permanent red powder, 6 kg of butyl acetate.

[0032] Preparation:

[0033] (1) The conventional physical mixing method is the first, that is, various materials are mixed in proportion and dispersed at a high speed of 2000rpm to prepare a paste-like product.

[0034] (2) Then pass through a sand mill to a fineness of 15 μm to obtain 100 kg of qualified products.

Abstract

The invention provides an oily red paste. It is characterized in that it consists of the following components by weight percentage: alkyd resin, propylene glycol methyl ether acetate, anti-skinning agent, dispersant, co-dispersant, red powder, and grinding mixture of butyl acetate. The oily red pulp of the invention has the characteristics of preventing floating and blooming, and simultaneously improving storage stability and dilution stability.

Description

technical field [0001] The invention belongs to the technical field of coatings, and relates to an oily red paste and a preparation method thereof. Background technique [0002] The oily red pastes currently on the market are all made of alkyd resins or synthetic fatty acid resins, and added wetting and dispersing agents to improve the dispersibility of the toner. It has the advantages of good tinting power and hiding power. The existing oily red pulp generally has disadvantages such as color floating and blooming, poor storage stability and dilution stability. Contents of the invention [0003] The object of the present invention is to provide an oily red slurry. [0004] The object of the present invention is to provide a kind of preparation method of oily red pulp, to overcome the above-mentioned shortcoming and deficiency that existing technology exists. For example, the existing red pulp has serious floating and blooming conditions, and technical defects such as pr...
