Problems solved by technology

[0004] During the preparation process of solid acrylic paint, it is necessary to inject the gel-like acrylic paint into the mold, and then release the mold after cooling down. However, because the gel-like acrylic paint has a certain viscosity, it is easy to stick to the mold, causing the Molding is difficult, which affects the preparation efficiency of solid acrylic paint

Embodiment 1

[0041] A kind of solid acrylic paint described in the embodiment of the present invention, described solid acrylic paint is made up of the raw material of following weight part:

[0042]

[0043]

[0044] Such as Figure 12 Shown, a kind of preparation method of solid acrylic paint, this method is suitable for preparing above-mentioned a kind of solid acrylic paint, and preparation method comprises the following steps:

[0045] S1: Select polyacrylic acid resin, toner, water and thickener, mix according to the ratio, and put them into the mixer to fully heat and stir evenly, and add the aqueous solution of film-forming aid during stirring;

[0046] S2: Add a PH regulator to the uniformly stirred solution, adjust the solution to weak alkalinity to form an alkaline stock solution, add an aqueous film-forming aid solution again, and stir;

[0047] S3: inject the alkaline stock solution into the molding equipment, drive the fan blade 34 to rotate through the motor 33, suck ...

Embodiment 2

[0058] Such as Figure 11 As shown in Comparative Example 1, another embodiment of the present invention is: the inner side of the housing 32 is affixed with an arc-shaped tube 41, and the inner ring of the arc-shaped tube 41 is sleeved on the outer ring of the ventilation hole 35, The inside of the bottom end of the arc-shaped tube 41 is fixedly connected to the filter screen 42; during use, when the outside air enters the housing 32 through the ventilation hole 35, the air passes through the arc-shaped tube 41 and the filter screen 42 to remove the dust from the outside. Filtration reduces the pollution of dust to the surface of the solid acrylic paint and improves the quality of the solid acrylic paint.

[0059] During work: the endless conveyor belt 1 drives the base 3 installed above and the cooling molding mold 2 to move, and the alkaline stock solution produced goes in and out of the cooling molding mold 2, and the water pump 39 sends water to the bottom of the water ta...

Abstract

The invention belongs to the field of pigments, and particularly relates to a solid propylene painting pigment and a preparation method thereof. Forming equipment comprises an annular conveying belt, a cooling forming mold, a base, a discharging sliding way, a half-moon-shaped plate, a sliding block, a spring, a spring, a hard rod, a soft rod and a pull rope. A cooling forming mold is conveyed through the annular conveying belt, the half-moon-shaped plate pushes the sliding block to be close to an S-shaped hole and pushes the hard rod, the soft rod and the pull rope to slide along the S-shaped hole, the cooling forming mold is released, the cooling forming mold rotates under the acting force of a torsional spring, the cooling forming mold collides with an impact block, and a solidified solid propylene paint pigment in the cooling forming mold is shaken off. Therefore, the probability that the solid propylene paint pigment is adhered to the cooling forming mold is reduced, and the preparation efficiency of the solid propylene paint pigment is improved.

Description

technical field [0001] The invention belongs to the field of pigments, in particular to a solid acrylic paint and a preparation method thereof. Background technique [0002] Acrylic paint is one of the most important painting materials in contemporary painting. Unlike oil painting, acrylic paint has higher requirements on the base material and its treatment. It is widely used on various types of substrates, even on metal and There is still strong adhesion on materials such as glass; acrylic paints can be used in combination with other materials to enrich colors and expressive effects. [0003] A Chinese patent with the publication number CN111334108A discloses a solid acrylic paint and its preparation method. The raw materials include: 3-10 parts by weight of toner, 1-5 parts of wetting and dispersing agent, 30 parts of deionized water -56 parts, 5-15 parts of hard acid, 30-40 parts of acrylic acid emulsion, 3-5 parts of sodium hydroxide, 7-10 parts of propylene glycol, the...
