Description

A kind of antibacterial modified back of the body paint
Technical field
The present invention relates to paint field, particularly the antibacterial modified back of the body paint of one.
Background technology
In each field, widely, and along with people are to the attention of health, functionalization, the environmental protection of paint are also accepted by market gradually in the application of paint.
There is a large amount of bacteriums and viral micro-organisms in environment, not only can affect the healthy of people, the film quality that also can be formed coating produces considerable influence.
Existing commercially available antibacterial modified back of the body paint adopts antibacterial metal ions (silver ions, cupric ion etc.) exchange adsorption is on porous carrier (zeolite powder etc.), antibacterial components is it can be used as to add in coating, slowly infiltrated from duct by metal ion, whole surface is made to be covered with the metal ion of positively charged, when bacterium contact plate face, electronegative bacterial cell can attract metal ion to enter cell paste, combine closely with chemical substance electronegative in system, destroy the bioelectricity balance of system when bacterium is copied, cause bacterial body protein denaturation simultaneously, destroy it breed and kill bacterium.
The shortcoming of this antimicrobial product is that adsorption rate is low, and effective metal adsorption rate is below 5%, and sterilization effect is poor.
Summary of the invention
In order to make up above deficiency, the invention provides a kind of environment-friendly type antibiotic modification back of the body paint of good anti-bacterial effect.
Technical scheme of the present invention is:
A kind of antibacterial modified back of the body paint, according to weight parts, composed of the following components: vibrin 10-30 part, solvent 6-20 part, dispersion agent 0.1-1 part, anti-settling agent 0.1-1 part, Rutile type Titanium Dioxide 10-35 part, process white 2-10 part, epoxy liquid 15-40 part, half methyl-etherified aminoresin 5-20 part, urea-formaldehyde resin 1-5 part, adhesion promoter 1-5 part, acid catalyst 0.1-1.5 part, Herba Caryopteridis Incanae 20-30 part, HERBA ARDISIAE JAPONICAE 10-20 part, Herba lysimachiae capillipedis 15-30 part.
This formula is that both solved the hardness defect of simple polyester system, the snappiness solving again simple ring oxygen system is not all right with the cold spelling epoxy preparation of vibrin; Make system hardness very high with half methyl-etherified amino, be applicable to low temperature line simultaneously; Solve due to the problem that paint film is thin, color-coating line temperature is low, paint film scratch resistance is poor, hardness is low.
Dispersion agent is in order to the Rutile type Titanium Dioxide in dispersion system, process white and adhesion promoter etc., can better grind, better color development.
Rutile type Titanium Dioxide is a type of titanium dioxide, has good opacifying power and ageing-resistant performance.
Process white is stopping composition, and oil number soft is high.
Adhesion promoter adds the tack of painting when being applied to ground.
Herba lysimachiae capillipedis, has antiviral effect, and infected by influenza first 3 type, B-mode, the third type and parainfluenza are all inhibited;
HERBA ARDISIAE JAPONICAE, has the effect of anti-bacteria and anti-virus, inhibited to streptococcus aureus, streptococcus pneumoniae, influenza virus;
Herba Caryopteridis Incanae, there is anti-microbial effect, streptococcus aureus, diphtheria corynebacterium are had to obvious restraining effect, also have good restraining effect to the bacillus such as typhoid fever, A type and paratyphoid B, Pseudomonas aeruginosa, large intestine, dysentery (Fu Shi) and Hemolytic streptococcus.
Preferably, described solvent is DBE and PMA mixed solvent, and the weight ratio of DBE and PMA is 1:2-2:1.
Preferably, described dispersion agent is high-molecular block copolymer dispersion agent.
Preferably, described anti-settling agent is castor oil derivative or organobentonite.
Preferably, described adhesion promoter is LTW.
Preferably, described acid catalyst is one or more in tosic acid, dinonylnaphthalene sulfonic acid, Witco 1298 Soft Acid.
The preparation method of described antibacterial modified back of the body paint, step is:
1) get Herba Caryopteridis Incanae, HERBA ARDISIAE JAPONICAE and Herba lysimachiae capillipedis, be crushed to 50-100 order, adopt analytically pure alcohol steep 3-5 hour, lixiviate is complete, and filtering filter residue, obtains antimicrobial fluid;
2) vibrin is dissolved in solvent, obtains polyester resin solution; By polyester resin solution and antimicrobial fluid Homogeneous phase mixing, then add heat extraction ethanol, the polyester resin solution of antibacterial components must be contained;
3) to containing adding dispersion agent, anti-settling agent, Rutile type Titanium Dioxide, process white, epoxy liquid, half methyl-etherified aminoresin, urea-formaldehyde resin, adhesion promoter, acid catalyst in the polyester resin solution of antibacterial components, Homogeneous phase mixing, obtains antibacterial modified back of the body paint.
Beneficial effect of the present invention is:
The present invention is with the cold spelling epoxy preparation of vibrin, and both solved the hardness defect of simple polyester system, the snappiness solving again simple ring oxygen system is not all right; Make system hardness very high with half methyl-etherified amino, be applicable to low temperature line simultaneously; Solve due to the problem that paint film is thin, color-coating line temperature is low, paint film scratch resistance is poor, hardness is low.
The made hardness of paint film of the antibacterial modified back of the body paint of the present invention reaches 4-5H, and snappiness is good, the curved 2-3T of T, shoes good, recoil 9J.
In addition, the present invention adopt Herba Caryopteridis Incanae, HERBA ARDISIAE JAPONICAE and Herba lysimachiae capillipedis Chinese medicine extract as antimicrobial component, three's synergy, can suppress or kill most of bacterium or virus, good anti-bacterial effect and nontoxic.
