Problems solved by technology

[0004] However, the paint described in the above-mentioned patents basically only has the functions of protection and installation. Generally speaking, the functions are relatively single, and still cannot meet the increasing living needs of existing people such as fire prevention, heat preservation, etc. and have some advantages in maintaining its stability. lacking

Embodiment 1

[0022] A kind of multifunctional and stable paint preparation method of the present embodiment comprises the following steps:

[0023] Step S1: Take the paint raw material as the main ingredient, add 8% by weight initiator, 20% wear-resistant agent, 14% flame retardant, 12% accelerator, and 18% thinner; put them into the mixer together Mixture A was obtained after crushing and adding water and stirring evenly.

[0024] Step S2: Mixture A is added with a solution weight percentage of 28% stabilizer, keep the temperature between 45°C and 50°C, and keep stirring for about 12 minutes.

[0025] Step S3: put the solution obtained in step S2 into a banbury mixer for 2-3 hours, and press the mixture after banbury into a twin-screw extruder through a forced feeding device for rapid rotation and chain breaking, with a rotation speed of 100- 159 rev / mins, make described paint. The paint prepared by this method is not only easy to make, no toxic gas is produced during the production pro...

Embodiment 2

[0027] This example is further optimized on the basis of Example 1. The flame retardant is prepared from the following raw materials in parts by weight: 2-methyl-5-oxocyclopent-1-enol propionate 12-15 parts, 1-2 parts of allyl isothiocyanate, 5-10 parts of tris(2-ethylhexyl) phosphate, 10-15 parts of toluene-diphenyl phosphate. The use of this flame retardant has the advantages of less addition, high flame retardant efficiency, low smoke, low toxicity, and wide application, and does not produce toxic gases during processing. Its dispersibility, physical, mechanical properties, thermal stability and flame retardant Performance has been improved and improved.

[0028] The initiator is ammonium persulfate.

[0029] Other parts of this embodiment are the same as those of Embodiment 1, so details are not repeated here.

Embodiment 3

[0031] This embodiment is further optimized on the basis of embodiment 2, and the anti-wear agent is nano-scale alumina or nano-silicon dioxide. The use of the wear-resistant agent can improve the wear resistance and scratch resistance of the product, and improve the self-cleaning performance of the product. Compared with traditional low-molecular-weight additives, ultra-high-molecular-weight anti-wear agents will not reduce the mechanical properties of the product, do not migrate, and the surface of the product is not greasy and smooth, and it is non-toxic and non-dangerous.

[0032] The accelerator is EP2220, EP3350 or EP-DS1300. The use of the accelerator can prevent the silver powder from falling off in the silver powder paint without turning black, and can improve the hardness and scratch resistance of the paint film. Adhesion promoting resin LTW is a soft special-purpose additive resin with wide compatibility, which is used to improve the inner layer adhesion of differe...

Abstract

The invention discloses a method for preparing multifunctional paint with stable properties. The method comprises the following steps: S1, by taking a paint raw material as a main material, crushing the following components in percentage by weight in a stirring machine: 8% of an initiator, 20% of a wearing resistant agent, 14% of a flame retardant, 12% of an accelerant and 18% of a diluent, and uniformly stirring with water so as to obtain a mixed material A; S2, putting 28 weight percent of a stabilizer into the mixed material A, keeping the temperature within 45-50 DEG C, and continuously stirring for 12 minutes; S3, performing internal mixing on the solution obtained in the step S2 for 2-3 hours in an internal mixer, so as to obtain the paint. The paint prepared by using the method is not only simple to prepare, but also free of toxic gas in the preparation process, good in wearing resistance and fire resistance, and is waterproof, good in air impermeability and stable in property,and dispersibility, physical and mechanical properties thermal stability and flame retardancy of the paint are all improved.

Description

technical field [0001] The invention relates to the field of multifunctional paints, in particular to a method for preparing a multifunctional and stable paint. Background technique [0002] The general components of paint include: film-forming substances, pigments, solvents, and additives. Many basic ingredients of desert oasis grass and wood paint are made of plant raw materials, which are pure natural substances. Paint is a chemical mixture coating that can firmly cover the surface of objects for protection, decoration, marking and other special purposes. The relatively authoritative book on paint technology in the Chinese paint industry defines it as follows: "Paint is a material that can be coated on the surface of an object by different construction techniques to form a solid film with firm adhesion, certain strength, and continuity. The film formed in this way is commonly called coating film, also known as paint film or coating." It belongs to organic chemical polym...
