Abstract
The invention discloses a paint applied to a profiled part. A preparation method of the paint comprises the following steps: weighing the following raw materials in parts by weight: 3 parts of mica, 2 parts of talcum powder, 5 parts of polyvinyl alcohol, 10 parts of chlorine vinegar resins, 4 parts of polysiloxane, 3 parts of butyl acetate, 2 parts of phthalic acid ester, 1 part of formaldehyde and 1 part of oligopeptide; and putting the raw materials into a high-speed dispersion machine and evenly stirring. The invention further discloses a dip coating process of the profiled part. The formula of the raw materials of the paint is reasonable, and the spraying of the paint is not required; and the only requirement is to dip and soak the paint. Therefore, the technical defect that the profiled part in an irregular shape is not suitable for being painted is overcome.
Description
Technical field
The invention belongs to paint field, be specifically related to a kind of paint for shaped piece and dipping process thereof.
Background technology
Paint is thickness oil colour, inflammable in not dry situation, water insoluble, is slightly soluble in fat, dissolves in alcohol, aldehyde, ether, benzene, alkane, be soluble in gasoline, kerosene, diesel oil.Paint has the performances such as anticorrosion, waterproof, grease proofing, chemicals-resistant, fast light, heatproof.Object is exposed among air, is subject to the erosion of oxygen, moisture etc., causes the breakoff phenomenons such as corrosion of metal, foxy, cement weathering.Be coated with coating at article surface, form layer protecting film, can stop or postpone generation and the development of these breakoff phenomenons, the work-ing life of various material is extended.So provide protection is a Main Function of paint.But there is many-sided defect in prior art paint, as unstable properties, hardness, sticking power are poor and erosion resistance is poor, long-term storage there will be layering, irregular colour, colour-change, thickness are unfavorable for the problems such as use, hazardous compound content is general higher, cannot reach the shortcomings such as national environmental standard.
Shaped piece refers to workpiece in irregular shape, and due to the irregular of its structure and diversity, technician, when spraying shaped piece, usually can not spray evenly, and spended time is long.How to obtain a kind of environment friendly and pollution-free and paint that performance perameter is higher, and shaped piece can be carried out dip-coating simply and effectively, belong to the technical problem that prior art is urgently to be resolved hurrily.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of environment friendly and pollution-free, and performance perameter is better, the paint that is applicable to shaped piece dip-coating.
For a paint for shaped piece, it is prepared as follows and forms,
Raw material is taken according to the weight part of 3 parts, mica, talcum powder 2 parts, polyvinyl alcohol 5 parts, vinyl chloride-vinyl acetate resin 10 parts, polysiloxane 4 parts, N-BUTYL ACETATE 3 parts, phthalic ester 2 parts, 1 part, formaldehyde, small peptide 1 part, be positioned in container, then put into high speed dispersor stir obtain paint first product, finally add microbial inoculum, addition, for painting 1% of just quality, stirs obtained.
Wherein, preferably, mica and talcous particle diameter all control at below 50um;
Preferably, small peptide is: ala-glu-Methionin;
Above-mentioned microbial inoculum is preferably bacillus pumilus microbial inoculum; The preparation method of this microbial inoculum is as follows: be first seeded on beef-protein medium by bacillus pumilus, 30 DEG C, make primary inclined plane to cultivate, then be inoculated in triangular flask and do the cultivation of vibration secondary liquid, then proceed to liquid fermentation tank and do three grades of liquid culture, to product, viable count reaches 2.0-4.0 × 10
8individual/gram; Then be drying to obtain; Wherein, drying temperature is 40 DEG C, and after dry, water content is 20%.The preferred bacillus pumilus CGMCC NO:3411(of bacillus pumilus (Bacillus pumilus) is see CN101824391A).
The present invention also carries the dipping process disclosing a kind of shaped piece, comprises the steps:
Shaped piece is carried out drying treatment, and moisture controlled, within 5%, carries out polishing smooth process with fine sandpaper, is then soaked in by shaped piece in the above-mentioned paint prepared, takes out shaped piece after 5 minutes, dry at being placed in 40 DEG C.
Wherein, the preparation method of above-mentioned microbial inoculum is not restricted to aforesaid method, can also be obtained by the conventional biology methods of this area.The bacillus pumilus CGMCC NO:3411 that the present invention uses can buy from China General Microbiological culture presevation administrative center.
The beneficial effect that the present invention obtains:
The present invention paints and adopts plurality of raw materials formula, by reasonable compatibility, without the need to spraying, only need soak, and solves the technology barriers that shaped piece is not suitable for due to out-of-shape spraying;
The present invention's paint has that hardness is high, pollution-free, strong adhesion and the feature such as not perishable;
The present invention is by adding a certain amount of small peptide, molecule crosslinked by physics and chemistry, each raw material is firmly adhered on shaped piece, difficult drop-off;
The present invention with the addition of suitable microbial inoculum, and its secretory product can form layer protecting film on top layer, and can absorb the acid contaminant in air, reaches protection and paints the object be not corroded.
