Abstract

The present invention belongs to a furnishing handicraft, which is made of high-elasticity microcellular foam raw material solidified by mesh macromolecules generated in a reaction between modified polyether resin and toluene diisocyanate, and is shaped by foam in a mould. The making process comprises: firstly, making a mould of an original object; applying a release agent on the inner cavity of the mould before pouring; mixing and stirring two kinds of raw material and injecting the mixture into the mould in the required quantity; pressing the outer edge of the mould tightly for 15 min to make the mixture foam and fill in the inner cavity; demoulding, finishing; spraying oil-soluble colors by layers and assembling. The product of the present invention has the advantages of vivid image, good hand feeling, good color and identical specific gravity to get the highly vivid effect.

Description

The handicraft flower, fruit and vegetable of high emulation

One. technical field: the arts and crafts that the invention belongs to furnishings.It is specifically related to a kind of product and manufacture craft thereof of novel artificial handicraft.

Two. background technology: along with the high speed development of people's material life, requirement in the cultural life also improves step by step, modern life is satisfied the back and is returned really requirement with regard to producing a kind of Piao of returning naturally, in brand-new modern times furnishings atmosphere, increase born plant of several energy reflections or the image of animal, can also display stay-in-grade handicraft there is some diffrent interest really for a long time if can mix the spurious with the genuine.Mostly the image of handicraft in prior art such as fruit, vegetables and animal is that with cloth, paper and plastics be raw material, the effect of the finished product of producing is very not true to nature, its outward appearance also can only far be seen, its feel is not right, it is hard touching up, its weight also differs greatly, and as easy as rolling off a log judgement is false, and such illness is difficult to cause the interest of modern consumer.In recent years, improve handicraft raising fidelity is the target that this field producer works hard always.The improvement useful plastic material injection moulding in back, useful fibre is made, also useful expanded polystyrene (EPS) is done, more than the effect of all products still can not be satisfactory, it is bad to have plenty of image, it is not right to have plenty of feel, and its proportion also falls far short, and the raising of fidelity is the bad difficult point that overcomes always.

Three. summary of the invention: the objective of the invention is to adopt new material and novel process, make a kind of handicraft flower, fruit and vegetable of high emulation, authentic image, the feel that also can make animal is true, proportion is identical, color and luster changes and the real on all four characteristics of original shape, can accomplish the stage of mixing the spurious with the genuine.

By as above design, the feature of the handicraft flower, fruit and vegetable of high emulation that this programme provides is that the each several part of this product all is to be made by the high-elastic microporous foam raw material that the netted big molecule that modified polyether resin and toluene di-isocyanate(TDI) reaction generate solidifies, foaming and molding in mould, it has the simulated effect that all there is height geomery, color, proportion, feel and hardness aspect with the original shape of the vegetables flowers and fruits of copying;

The feature of manufacture craft that realizes the handicraft flower, fruit and vegetable of this high emulation is that its operating process is as follows:

1. the decomposable part of the original shape of artificial handicraft is disassembled, make the former that contains it with the body of each several part;

2. the A material of modified polyether resin is expected that with the B of toluene di-isocyanate(TDI) mixing the back in 100: 30 ratio stirs fully under 25+5 ℃;

3. coat releasing agent at dies cavity before the cast, will calculate in the mixing material material injecting mould chamber of consumption;

4. the mould appearance is exerted pressure, the pressing mold time was at 15～20 minutes;

5. the each several part with goods adopts oil-soluble color and pigment to spray by different level with spray gun;

6. each painted other part is pressed the assembling of original structure, connect with polyester is gluing;

Wherein, the proportioning of its A material is composed as follows:

Connect a polyethers 48%;

High-elastic polyethers 48%;

Diethanol amine 0.96%;

Silicone oil 0.38%;

Triethylene diamine 0.19%;

Dibutyl tin laurate 0.048%;

Add water to 100%.

Adopt this programme can embody following superiority: 1. it to have adopted netted big molecule microcellular foam material be raw material, the good hand touch of its goods, complete identical during touch, and texture is arranged with the tactility of true thing; 2. its image product is good, because delivery is careful, its product not only geomery is identical, the natural convex-concave of the train of thought on its more lip-deep details such as the leaf, fruit surface growth, and the vegetables dehydration after the trickle fine hair of trickle wrinkle, lotus leaf surface can keep the globule for a long time the lines trend on last rolling, animal skin etc. can both show the stage that can accomplish mixes the spurious with the genuine is difficult to differentiate very carefully; 3. this technology can accomplish to adjust the proportion of product in a big way, can make the proportion of product and original shape very approaching, proportion in product can be adjusted in 0.3～0.9 scope, be made in as more solid Chinese cabbage proportion in 0.7～0.9 the scope, but not solid then can being made in 0.3～0.5 scope as its proportions such as spinach, rapes has the greatly sense of reality when therefore taking in the hand; 4. the color and luster on its surface is good, with various oil-soluble colors and pigment layering spraying, and the crow that its surface should crow, this is bright bright, and its image is really true to life; 5. the A that this programme adopted expects, the cost of B material is not high, but its effect is a kind of superior and economic technical scheme far above its general prior art.

Four. the specific embodiment: the embodiment that now further specifies this programme.The handicraft flower, fruit and vegetable of this high emulation comprises following several big class:

First. leaf type combination greengrocery: Chinese cabbage, cauliflower, onion, cabbage, rape etc.;

Second. rhizome type dish class: radish, carrot, cucumber, balsam pear, bamboo shoots etc.;

Third. fruits: lemon, persimmon, apple etc.Also can make in addition

Fourth. foodstuff: bread, sausage, little tripe etc.;

Penta. cereal crops class: the wheat head, corn, Chinese sorghum;

Oneself. animal class: cat, dog, bird, bear, deer, ox, sheep etc.

More than the way of various products wide, as long as the mould that can shell out just can make various artificial handicrafts.Product lot quantity hour can use plaster mold, can adopt punching block or aluminum dipping form when big in batches.

A material, B material have been finished following variation in operation:

1. chain propagation reaction, it refers to the reaction that primary raw material polyethers and isocyanates generate polyurethane, the radical reaction between ester and the alcohol just,

2. venting reaction refers to that isocyanates and water react the reaction of emitting carbon dioxide,

3. the reaction of amido and isocyanates refers to that the amine of preorder generation generates the reaction of derivative again with the isocyanates effect,

4. crosslinked and branching reaction refers to hydrogen on the nitrogen-atoms and isocyanate reaction in the carbamate groups, and this reaction makes linear polymer form branching and crosslinked structure,

It is not corrode nondiscolouring to never degenerate that this kind artificial handicraft also has characteristics, can long preservation display, after this trial production success, do not see earlier the person and clap hands invariably and applaud.
