preparation example Construction

[0029] The preparation method of described pearl paste, comprises the following steps:

[0030] (1) Crushing the biomass material, adding water and stirring, adding alkali and then adding hydrogen peroxide solution, standing for 36-48h, filtering, and leaving the supernatant;

[0031] (2) Take 200 parts of supernatant liquid and 150 parts of pearlescent powder, and mix them evenly to obtain pearlescent paste.

[0032] Further, the biomass material is straw, rice straw and the like.

[0033] Further, the crushing particle size is 4-15mm.

[0034] Further, the stirring is low-speed stirring, and the speed is controlled at 200-500r / min.

[0035] Further, the concentration of the alkali solution is 100g / L, 2L-3L.

[0036] Further, the added amount of hydrogen peroxide is 0.3-0.6wt%, and the bleaching effect is better within this range.

[0037] A kind of preparation method of novel pearlescent paint, comprises the following steps:

[0038] Add thixotropic thickener, dispersan...

Abstract

The invention discloses a novel pearlescent paint and a preparation method thereof. The pearlescent paint is prepared from the following raw materials in parts by weight: 250 to 280 parts of water, 3to 6 parts of a thixotropic thickening agent, 2 to 5 parts of a dispersing agent, 1 to 3 parts of a lubricating agent, 1 to 3 parts of a defoaming agent, 340 to 360 parts of pearlescent slurry, 15 to20 parts of a film-forming agent, 340 to 360 parts of acrylic emulsion and 1 to 5 parts of a sterilizing agent. Paper pulp waste liquid is prepared at a normal temperature by using alkali and hydrogenperoxide, the prepared paper pulp waste liquid is directly applied to the production of the novel pearlescent paint, so that the harm of inhaling pearl powder with extremely low density into a humanbody is reduced, and the production process is greatly improved by preprocessing the pearl powder by using the paper pulp waste liquid. Due to the addition the paper pulp waste liquid in the production process, the color and layering of the prepared pearlescent paint are greatly improved, and the defect of planarization of a conventional pearlescent paint is overcome.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a novel pearlescent paint and a preparation method thereof. [0002] technical background [0003] Pulp waste liquid is an acid / alkali type substance discharged from paper mills. With the utilization and development of pulp waste liquid, relying solely on paper mills can no longer meet the actual production needs. With the increase in the use of pulp waste liquid, most of the production of pulp waste liquid still stays in the basic high-temperature alkaline environment, which has great requirements for the production conditions, and due to the The high temperature environment in the environment is a kind of damage to the operator to a large extent. The present invention proves the method of using alkaline solution and hydrogen peroxide solution instead of high temperature alkali treatment, so as to greatly reduce the operating cost. difficulty. Moreover, using the v...
