[0038] The components and weight ratio of oily medium yellow pulp are as follows:

[0039] 55 kg of alkyd resin, 20 kg of propylene glycol methyl ether acetate, 0.1 kg of anti-skinning agent, 3 kg of dispersant, 0.5 kg of synergistic dispersant, 10 kg of medium yellow powder, 11.5 kg of butyl acetate.

[0040] Preparation:

[0041] (1) The first conventional physical mixing method is to mix various materials in proportion and disperse at a high speed of 2000rpm to prepare a paste-like product.

[0042] (2) Then pass through a sand mill to a fineness of 10 μm to obtain a qualified product.

Embodiment 3

[0044] A formula (weight) of oily yellow pulp: oily lemon yellow pulp.

[0045] The components and weight ratio of oily lemon color paste are as follows:

[0046] 50 kg of alkyd resin, 20 kg of propylene glycol methyl ether acetate, 0.1 kg of anti-skinning agent, 2 kg of dispersant, 0.5 kg of synergistic dispersant, 14 kg of lemon yellow powder, 13 kg of butyl acetate.

[0047] Preparation:

[0048] (1) The first conventional physical mixing method is to mix various materials in proportion and disperse at a high speed of 1500rpm to prepare a paste-like product.

[0049] (2) Then pass through a sand mill to a fineness of 15 μm to obtain a qualified product.

Abstract

The invention provides oily yellow pulp. The oily yellow pulp is a grinding mixture of alkyd resin, propylene glycol methyl ether acetate, an anti-skinning agent, a dispersing agent, a synergistic dispersant, yellow powder and n-butyl acetate. The oily yellow pulp provided by the invention has the characteristics that flooding and floating are prevented, and simultaneously, the storage stability and dilution stability are improved.

Description

technical field [0001] The invention belongs to the technical field of coatings, and relates to an oily yellow paste and a preparation method thereof. Background technique [0002] The oily yellow 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. Existing oily yellow 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 yellow slurry. [0004] The object of the present invention is to provide a kind of preparation method of oily yellow slurry, to overcome the above-mentioned shortcoming and deficiency that existing technology exists. For example, the existing yellow pulp has serious floating and blooming conditions, and technical de...
