Background technology

In recent years, with the various product of the natural materials hand wovens such as rattan, wicker, bamboo cane, all kinds of stalks, there is the wide market space, this series products is many as indoor furniture, goods of furniture for display rather than for use and daily living article, because it has the advantage of nature, environmental protection, pole is liked by human consumer, and a lot of product is sold abroad.Because fabric natural material is in use affected by environment, very easily damage by worms rotten, make moist mouldy, thus serious reduction work-ing life and use properties, therefore, need at product surface spray coating antifouling paste in actual production process, require that this kind of antifouling paste in conjunction with material feature, not only will will possess good antiseptic property simultaneously, also will have the feature of environmental protection of height and lower production cost.

Summary of the invention

The object of the invention is to, provide a kind of aqueous anticorrosion paint containing Herba Houttuyniae active antibacterial ingredient, in order to achieve the above object, the technical solution used in the present invention is as follows:

A kind of aqueous anticorrosion paint containing Herba Houttuyniae active antibacterial ingredient, it is characterized in that, this antifouling paste is made up of the raw material of following weight part: the water-borne acrylic resin emulsion 30-40 of dry Herba Houttuyniae 0.1-0.3, phenyl silicone oil 1-2,1,5-PD 5-8, solid content 40-50%, Sodium dodecylbenzene sulfonate 1-2, polyvinyl alcohol 2-4, dehydrated alcohol 4-5, deionized water 8-11, auxiliary agent 1-2;

Auxiliary agent is made up of the raw material of following weight part: nano zine oxide 3-5, ethylene glycol phenyl ether 1-2, cm-chitosan 1-2, nano rare earth cerium colloidal sol 1-2, deionized water 10-12, polymine 1-3, preparation method is: be first dissolved in deionized water by cm-chitosan, polymine, again other leftover materials are added in mixing solutions, and stir with the speed of 500-600 rev/min, after material dispersion is even, under 60-80 DEG C of condition, mixture is condensed into paste, after being cooled to room temperature and get final product.

Described a kind of aqueous anticorrosion paint containing Herba Houttuyniae active antibacterial ingredient, its preparation method is as follows:

(1) first dry Herba Houttuyniae is dropped in the solution by deionized water and ethanol mixed preparing, closed water bath heating 2-3h, bath temperature is 60-80 DEG C, after heating terminates, solution is filtered, gained filtrate adds polyvinyl alcohol, Sodium dodecylbenzene sulfonate, phenyl silicone oil after being cooled to room temperature, be stirred to material to dissolve disperse completely, gained material is for subsequent use;

(2) by other remaining component and step (1) gained mixing of materials, after continuing to be uniformly mixed 1-2h, to obtain final product.

Compared with prior art, antifouling paste advantage of the present invention is: the water extraction of the dry Herba Houttuyniae of adding in raw material has natural Antimicrobial preservative composition, the antiseptic power of emulsion can be improved, phenyl silicone oil can improve the water-resistant capacity of paint film, be combined with auxiliary film forming, the auxiliary agent of dry effect and other remaining component again, when the present invention being painted be applied to baskets craft surface, excellent corrosion-resistanting waterproofing performance can be reached, its product processes is simple, cost is lower, without unpleasant odor, Environmental Safety.

Embodiment

Embodiment

The antifouling paste of the present embodiment is made up of the raw material of following weight part: the water-borne acrylic resin emulsion 40 of dry Herba Houttuyniae 0.2, phenyl silicone oil 1,1,5-PD 8, solid content 50%, Sodium dodecylbenzene sulfonate 1, polyvinyl alcohol 4, dehydrated alcohol 5, deionized water 10, auxiliary agent 1;

Auxiliary agent is made up of the raw material of following weight part: nano zine oxide 5, ethylene glycol phenyl ether 2, cm-chitosan 1, nano rare earth cerium colloidal sol 1, deionized water 10, polymine 2, preparation method is: be first dissolved in deionized water by cm-chitosan, polymine, again other leftover materials are added in mixing solutions, and stir with the speed of 600 revs/min, after material dispersion is even, under 60-80 DEG C of condition, mixture is condensed into paste, after being cooled to room temperature and get final product.

The preparation method of this antifouling paste is as follows:

(1) first dry Herba Houttuyniae is dropped in the solution by deionized water and ethanol mixed preparing, closed water bath heating 3h, bath temperature is 60-80 DEG C, after heating terminates, solution is filtered, gained filtrate adds polyvinyl alcohol, Sodium dodecylbenzene sulfonate, phenyl silicone oil after being cooled to room temperature, be stirred to material to dissolve disperse completely, gained material is for subsequent use;
