Abstract
The making process of unsaturated resin handicraft for decorating aquarium includes the following steps: 1. mixing promoter in 0.15-0.25 wt% and0.4-0.6 wt% with unsaturated polyester resin and curing to obtain blank; 2. trimming the blank and eliminating sharpening parts; 3. soaking the blank in alkali solution with pH value over 11 for 5-10 min, washing, soaking in acid solution of pH value 4-5 for 10-15 sec, and washing to neutral or weak acid in the surface; 4. drying; and 5. closing the surface of the blank with non-toxic or low-toxicity paint layer. The handicraft thus made is beautiful, and has no harmful matter leached to water.
Description
Technical field
The present invention relates to be applicable to the preparation method of the handicraft article made of unsaturated resin of decorating aquarium.
Background technology
In order to improve sight and aesthetic feeling, in the aquarium of being everlasting, place ornamental handicraft, these handicrafts more importantly are to be immersed in the water can not shed or the stripping harmful substance except must having profile attractive in appearance, form true to nature, and the aquatic organism in the aquarium is produced harm.
Unsaturated polyester resin is to make one of the most common material of ornamental handicraft, it is the linear polymer that is formed by unsaturated dibasic acid, monounsaturated dicarboxylic acid and dihydroxylic alcohols polycondensation, form resin solution through the crosslinking styrene dilution with certain viscosity, add materials such as promoter, curing agent in use again, make the two key generation free radicals copolymerization reactions in styrene monomer and the unsaturated polyester ester molecule, final interlinkage becomes the resin of three-dimensional-structure.Its advantage is a curing molding at normal temperatures and pressures, and manufacture craft is simple, quality good, cost is low.Yet the unsaturated polyester resin that utilizes existing prescription and process to make contains a large amount of harmful substances, is unsuitable for as the decorating aquarium handicraft.
Summary of the invention
The objective of the invention is to adopt unsaturated polyester resin is raw material, and a kind of method of making harmless, inexpensive decorating aquarium with handicraft is provided.
The preparation method of unsaturated resin handicraft for decorating aquarium provided by the invention comprises the steps:
(1) choose unsaturated polyester resin, 1.5-2.5 ‰ adds promoter by weight, and 4-6 ‰ adds curing agent by weight, and curing molding is made base substrate;
(2) base substrate is repaired, removed sharp-pointed portion;
(3) base substrate after will repairing is with pH value after the dipping by lye 5-10 11 or more minute, cleaning, then with the acid soak 10-15 of pH value 4-5 after second, clean to the billet surface pH value and be neutrality or faintly acid;
(4) make body drying after the cleaning;
(5) with the enamelled coating sealing of billet surface with nontoxic or low toxicity.
Needs according to goods are made can also comprise steps such as colored drawing, assembling.
Preparation method provided by the invention is characterized in adopting common unsaturated polyester resin, by the consumption of strictness control promoter, curing agent, handle through alkali, pickling base, and it is with the sealing of the enamelled coating of nontoxic or low toxicity, make not only good looking appearance of the handicraft made, and harmless, inexpensive.
Utilize said method can make the handicraft of various moulding, these goods long period of soaking can the stripping harmful substance in water yet, can the biology in the aquarium not worked the mischief.These goods can use separately, also can be used in combination with other ornaments, are a kind of decorations, beautify the high-quality ideal product of aquarium.
Embodiment
Below in conjunction with embodiment the present invention is described in further detail:
(1) base: select commercially available unsaturated polyester resins for general purpose for use, 2 ‰ adding cobalt iso-octoates or cobalt naphthenate are as promoter by weight, mixture is injected the mould of making in advance, and 4-5 ‰ adds methyl ethyl ketone peroxide as curing agent by weight, and curing molding is made base substrate at normal temperatures.
(2) finishing: comprise the mill end, deburring etc., the sharp-pointed edge of removing base substrate corner, hole, protuberance forms slick and sly surface, in order to avoid scratch the aquatic organism in the aquarium.When needs are mended the base finishing, should adopt innocuous substance, can not use greasy filth etc.
(3) wash base:
A) in order to reach clean effect preferably, adopt highly basic such as NAOH, thin up, pH value must reach more than 11, and the base substrate after will repair is this dipping by lye 5-10 minute, puts into clear water towards clear 10-20 second, the alkali lye of remnants is cleaned, and billet surface does not have sticking hand, greasy feeling gets final product.
B) soak 10-15 second with the hydrochloric acid dilution of pH value 4-5 then, billet surface generates when removing the natron processing salt and other impurity, putting into clear water thoroughly cleans the surfaces externally and internally of base substrate, be neutrality or faintly acid and no-sundries adhesion to the billet surface pH value, in order to avoid influence the firmness of enamelled coating.
(4) drying: in order to guarantee to evaporate fully in the base substrate, reach abundant drying, improve the quality of products, billet surface moisture natural air drying after will cleaning earlier, put into drying baker then and dried 60-90 minute down, make its finish-drying, in order to avoid influence the enamelled coating quality at 70-80 ℃.
(5) priming paint sealing: select low toxicity or nontoxic material for use, coat with lacquer nontoxic industrial urushoil, the Tianna solution that Co., Ltd produces as ShenZhen,GuangDong ten thousand sharp systems, urushoil, Tianna solution by weight 1: after the 8-10 allotment, brushing is on the inside and outside all surfaces of base substrate, seal, prevent that harmful substance is disengaged in the base substrate, the aquatic organism in the aquarium is worked the mischief.
(6) colored drawing: the priming paint natural air drying is after 6 hours, according to decorating needs, and also look, colored drawing in its surface, colouring, colored drawing also must be selected nontoxic material for use.
(7) assembling: according to the product function needs, can also bondingly go up other ornaments such as pasture and water, soft artificial thing, and the fit on motor drive mechanism etc., the use of accessory also should meet innoxious requirement.
Utilize the handicraft long period of soaking that said method makes also can the stripping harmful substance in water, can the biology in the aquarium not worked the mischief, be a kind of decoration, beautify the high-quality ideal product of aquarium.
More than provide one to realize specific embodiments of the invention; but this is not to be limitation of the present invention; do not leaving spirit of the present invention and design, that has done it will be apparent to those skilled in the art that changes and improvements, still belongs to the scope of protection of the invention.
