[0040] Preparation:

[0041] (1) It is the first conventional physical mixing method, that is, various materials are mixed according to the proportion and dispersed 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] An oily yellow pulp formulation (weight): oily lemon yellow pulp.

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

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

[0047] Preparation:

[0048] (1) It is a conventional physical mixing method, that is, various materials are mixed according to the proportion and dispersed 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 sold on the market are all made from alkyd resins or synthetic fatty acid resins, and wetting and dispersing agents are added to improve the dispersibility of toners. It has the advantages of good tinting power and good covering power. Existing oily yellow paste generally has the disadvantages of floating color, serious blooming, poor storage stability and dilution stability. SUMMARY OF THE INVENTION [0003] An object of the present invention is to provide an oily yellow slurry. [0004] The purpose of the present invention is to provide a preparation method of oily yellow slurry to overcome the above-mentioned shortcomings and deficiencies in the prior art. For example, the existing yellow slurry has serious floating color and blooming, and the technical defects of pr...
