Abstract
The invention discloses a kind of antibacterial baskets craft Inorganic whisker coating, inorganic coating is used in combination by this coating with aqueous organic coating, having prepared a kind of Inorganic whisker coating with good filming effect and barrier propterty, the inorganic film former wherein used is polyacrylamide, chitosan microball.The gel powder that tetraethyl orthosilicate and lithium hydroxide solution composite hydrolysis hydridization are formed, effectively improve the defect of Conventional Portland coating, it is more preferable with the compatibility of macromolecule emulsion, and the organic film former allocated with dispersions of polyurethanes and natural emulsion possesses excellent filming performance, it is tough and tensile high-elastic, and more preferably, this coating can form nontoxic, firm, high-elastic, antibacterial film layer to feel on baskets craft surface, improve ornamental value and the service life of artware, economical and practical.
Description
Technical field
The present invention relates to aqueous artware paint technical field, particularly relate to a kind of antibacterial baskets craft with inorganic-have
Machine composite coating.
Background technology
Weaving is one of the most ancient handicraft of the mankind, and the stem of plant, leaf, skin through processing, are used multiple volume by it
Knitting maneuver and weave various daily living articles and artware, this series products has natural, pure and fresh, unique artistic style, economical
Being worth and also step up, market demand is bigger.
The natural braided material used due to baskets craft, is affected relatively big by extraneous factor, and do not properly protect measure
The most destroyed, affect aesthetic property and the service life of product, apply more be also the most direct means of defence be on surface
Coating coating, but it is different from most products, and the requirement of coating in addition to environmental protection, be it is also desirable to have by baskets craft
Relatively low production cost, IMAGE, it is prone to cleaning etc. performance.Inorganic coating is that a class is with silicate, Ludox etc.
Inorganic material is the coating of main film forming substance, and it has the advantages such as the good feature of environmental protection, antibacterial and mouldproof, weather-proof, fire protection flame retarding,
Being more suitable for baskets craft use than organic coating, but it also has the shortcomings such as film-formation result is the best, easy to crack, use is subject to
To limiting.The performance of inorganic/organic composite coating inquired in " preparation of Lithium metasilicate base composite coating and performance study " literary composition, system
The composite coating filming performance obtained is improved, and adhesive force and intensity are the most superior, but this coating is mainly used in sand
On slurry base material, if be applied on braided material to exist sophistication not, poor sealing performance etc. shortcoming, need to do further
Improvement.
Summary of the invention
The object of the invention is contemplated to make up the defect of prior art, it is provided that a kind of antibacterial baskets craft with inorganic-have
Machine composite coating.
The present invention is achieved by the following technical solutions:
A kind of antibacterial baskets craft inorganic-organic compound coating, this coating is made up of the raw material of following weight portion: genuine milk
Glue 5-8, solid content are the aqueous pu dispersions 30-40 of 40-50%, polyacrylamide 0.8-1, chitosan microball 0.5-
0.8, tetraethyl orthosilicate 2-3, concentration are the lithium hydroxide aqueous solution 15-18 of 0.5-1.5mol/L, dehydrated alcohol 20-30, froth breaking
Agent 0.1-0.2, deionized water 10-15.
The preparation method of described a kind of antibacterial baskets craft inorganic-organic compound coating is as follows:
(1) putting in deionized water by polyacrylamide, stirring is completely dissolved to it, adds chitosan microball subsequently, continues
Stirring makes it be uniformly dispersed, and is configured to mixed solution standby；
(2) by dehydrated alcohol and lithium hydroxide aqueous solution mixing and stirring, it is subsequently added tetraethyl orthosilicate, hybrid reaction 30-
Solution prepared by step (1) it is slowly added to after 50min, stirring while adding, sonic oscillation reaction 20-30min after interpolation, instead
Should terminate post-heating to dried after 50-60 DEG C of aged gel 4-5h, the xerogel of gained grinds, and crosses 600-800 mesh
Sieve standby；
(3) by aqueous pu dispersions, natural emulsion mixing high-speed stirred dispersion 40-50min, it is subsequently added step (2) system
Standby material, continues dispersed with stirring 20-30min, is eventually adding other leftover materials, continue after dispersed with stirring 10-15min through
Filter, pack and get final product.
Inorganic coating is used in combination by the present invention with aqueous organic coating, has prepared one and has had good filming effect and prevent
Protecting the inorganic-organic compound coating of performance, the inorganic film former wherein used is polyacrylamide, chitosan microball.Positive silicic acid
The gel powder that ethyl ester and lithium hydroxide solution composite hydrolysis hydridization are formed, effectively improves lacking of Conventional Portland coating
Falling into, it is also more preferable with the compatibility of macromolecule emulsion, and the organic film forming allocated with dispersions of polyurethanes and natural emulsion
Agent possesses excellent filming performance, and it is tough and tensile high-elastic, feel more preferably, this coating can be formed on baskets craft surface nontoxic,
Firmly, high-elastic, antibacterial film layer, improve ornamental value and the service life of artware, economical and practical.
Detailed description of the invention
A kind of antibacterial baskets craft Inorganic whisker coating, this coating is made up of the raw material of following weight portion: sky
So latex 5, solid content be 40% aqueous pu dispersions 30, polyacrylamide 0.8, chitosan microball 0.5, positive silicic acid second
Ester 2, concentration are the lithium hydroxide aqueous solution 15 of 0.5mol/L, dehydrated alcohol 20, defoamer 0.1, deionized water 10.
Its preparation method is as follows:
