Abstract

The lightening foam artwork is made by filling fluorescent powder and dying material to polyether for sufficient blending, with dye 8-10%, fluorescent powder 5-55%, increasing process temperature 2 degrees to 28-30 degrees, adding 0.05% ethanediamine on the basis of the original prescription, increasing mass portion of octanoic acid tin to 1.025 times, getting the required strips through cutting, punching, winding the foam strips along the iron wires to form twigs, combining with the frames to form into branches, spraying a dilute polyvinyl acetate agent, glacial acetic acid, or softening agent miscible liquids, knitting white fur on the high voltage static generator to form white snow to make vividness.

Description

A kind of preparation method of luminous sponge artwork

Technical field

The present invention relates to a kind of preparation method of luminous sponge artwork, spongiology title flexible polyurethane foam.

Background technology

At present, the Christmas ornament gift, particularly adornment in red-letter day such as Christmas tree, Christmas garland of people's use, most plastic pvc materials that use are made, owing to contain human harmful substances such as plasticizer, antiaging agent in the plastics, therefore progressively eliminated or limit, especially European Union market by market.Sponge only is used for small stores such as sofa, mattress usually as packing material, owing to be subjected to the restriction in the making of foam production technology, from can taking place, oxidation forms xanthochromia in daylight and air in addition, color is comparatively single, and sponge is painted, especially become blackish green after, be processed into the christmas crafts product by certain method again, can improve use value greatly.

Summary of the invention

The preparation method that the purpose of this invention is to provide a kind of luminous sponge artwork.

For achieving the above object, the present invention is achieved in that the main material of sponge is polyethers, isocyanates, silicone oil, stannous octoate, triethylene diamine, carrene and water, during production polyethers, silicone oil, stannous octoate, triethylene diamine, carrene and water are stirred, whipping temp is at 26-28 ℃, add isocyanates again evenly, stirred again 5 seconds, after compound poured into foam in the mould, painted mainly is to adopt to add mill base, all belongs to known technology.The present invention is in this production process, use acid dyes to replace the mill base that uses in traditional foam process, earlier dyestuff is got ready by required color, again luminescent powder or fluorescent material and dyestuff are added in the polyethers as a kind of filler and go fully to stir, dyestuff is the 8-10% of polyethers, luminescent powder or fluorescent material are the 5-55% of polyethers, in foam process, former temperature is increased in 2 ℃ to the 28-30 ℃ scopes, triethylene diamine increases by 0.05% amount on the basis of original formulation, with this strengthen whole sponge-rubber pad in rise sending out process gel and the reaction of catalysis, avoid silk floss to wrap in the adding dyestuff, the cracking that can form behind the materials such as luminescent powder, the weight portion of amount on the basis of original formulation of stannous octoate is increased to 1.025 times simultaneously, can strengthen the cross-linking reaction of whole continuous bag like this, the change of whole catalyst weight part, the sponge-rubber pad that can make the entire belt luminous effect is in milky white, rise and send out, gel, accomplish the end in view in the process of venting, solved the single defective of sponge color simultaneously.

The described sponge of this technology is made its leaf bar that forms required design shape through cutting, punching press, sponge leaf bar is wrapped on the iron wire that designs forms branch again, be bundled into the tree shape with skeleton again.

To spray the polyvinyl acetate emulsion adhesive on the branches and leaves of moulding or the tree body in the preparation method of the present invention, adhesive need dilute and add an amount of glacial acetic acid or softening agent, make the existing suitable viscosity in sponge sprinkling back on tree body or the branches and leaves, not making again hardens after the cavernous body drying causes fracture, in the static case, knit white suede by HV generator then, allow cyan sponge set and form white snow on the body, make goods that emulation more be arranged.

Specific implementation method

Earlier sponge is produced the known technology needed raw material: polyethers, isocyanates, silicone oil, stannous octoate, triethylene diamine, carrene, water, components by weight percentage: polyethers 55.00%, isocyanates 34.00%, silicone oil 1.17%, stannous octoate 0.20%, triethylene diamine 0.13%, carrene 7.00%, water 2.50%.Account for the ratio of total amount 55% amount again in polyethers, with account for the luminescent powder or the fluorescent material 11% of polyethers amount 20%, the dyestuff 4.4% that accounts for polyethers 8% is got ready, required luminescent powder or fluorescent material and dyestuff added in the polyethers as a kind of filler go fully to stir, be put into this emulsion in the bucket again, adding silicone oil, stannous octoate, triethylene diamine, carrene, water again stirs, add isocyanates again evenly, stirred again 4～6 seconds, pour in the mould this compound into foaming and be sponge, the material temperature is 28-30 ℃ during stirring.Sponge is made its leaf bar that forms required design shape through cutting, punching press, sponge leaf bar is wrapped on the iron wire that designs forms branch again, be bundled into the tree shape with skeleton again.To spray the polyvinyl acetate emulsion adhesive on the branches and leaves of moulding or the tree body in the preparation method of the present invention, adhesive need dilute and add an amount of glacial acetic acid or softening agent, make the existing suitable viscosity in sponge sprinkling back on tree body or the branches and leaves, not making again hardens after the cavernous body drying causes fracture, in the static case, knit white suede by HV generator then, allow cyan sponge set and form white snow on the body, get product.

When the present invention made ornamental part, the configurable prior art of its base made the rotation of tree body and is provided with automatic articulatory system.

Claims

1, a kind of preparation method of luminous sponge artwork, it is characterized in that in the sponge foaming process, earlier with acid dyes, luminescent powder or fluorescent material are as a kind of filler, add in the polyethers and go fully to stir, the back adds silicone oil, stannous octoate, triethylene diamine, carrene and water, stir, whipping temp is 28-30 ℃, add isocyanates after stirring again, stirred again 5 seconds, after pour in the mould compound into foaming and be required painted sponge, with the cutting of blackish green sponge process, punching press makes it form the leaf bar of tree, again sponge leaf bar is twined on the iron wire and form branch, be bundled into the tree shape with skeleton again, with spraying the polyvinyl acetate emulsion adhesive of dilution and the mixed liquor of glacial acetic acid or softening agent on the branches and leaves of moulding or the tree body, in the static case, knit white suede by HV generator again, allow form in vain on the cyan sponge tree body and avenge.

2, the preparation method of a kind of luminous sponge artwork according to claim 1 is characterized in that dyestuff is the 8-10% of polyethers, and luminescent powder or fluorescent material are the 5-55% of polyethers, and in the foam process, temperature is in 28-30 ℃ of scope.
