Abstract
The invention relates to a one-step molding technology of green FRP (Fiber Reinforce Plastic) on the back of a white acrylic bathtub. The one-step molding technology comprises the following steps: firstly, carrying out plastic molding according to the mould shape of the bathtub by using white acrylic sheet materials of high-concentration color paste so as to complete a plastic molding piece of the bathtub; secondly, preparing green resin; thirdly, invertedly buckling the plastic molding piece of the white acrylic bathtub onto a last-shaped frame to spray green FRP, after the green resin is heated in a stirring barrel, firstly uniformly spraying the green resin to the bottom of the white acrylic bathtub till the thickness is 2mm through a spray gun, putting bathtub reinforcing base plates, then spraying the green FRP on the back of the molding piece of the white acrylic bathtub in an omnibearing manner, spraying uniformly till the thickness of a fiber layer added with the green resin is 3-4 mm, and then compacting by manually pushing a roller; and fourthly, curing for 2 h after the green FRP is coated on the back of the white acrylic bathtub, cutting and shaping to complete the production. The adoption of the technology disclosed by the invention can ensure the product quality without cross color, and the production efficiency also can be greatly promoted.
Description
Technical field
The present invention relates to a kind of spraying coating process of acrylic bathtub, particularly the green FRP one-shot forming technique in a kind of white acrylic bathtub back side.
Background technology
General white acrylic bathtub product is according to after product-forming mould plastic uptake acrylic board material forming, the acrylic thickness of bath base only has 50～80 μ m, be easier to printing opacity, so generally to add fiberglass layer (FRP layer) be all light colour to the resin at the bathtub back side, the FRP layer of light colour is not easy to see through white acryl plates, can not affect the outward appearance of product, as used dark colour FRP layer color will be seen through to acrylic face, ring bathtub appearance, be called and wear look.For preventing to wear look phenomenon, common way is: during production, at white acrylic surface of shaped parts, first spraying one deck light-colored resin fiber increases thickness screening look, then sprays dark colour resin fibre, avoids wearing look.But according to such mode of production, more than producing a product needed spraying secondary, often production efficiency is low.For enhancing productivity, what now need solution is the spraying number of times that how to reduce the acrylic bathtub of production back side dark colour FRP.
When the production white acrylic back side sprays the bathtub of green FRP, spraying coating process completes at twice, and the resin that first sprays one deck white adds fiber, spray again after cured one deck green resin and add fiber, twice spraying not only increased workload, and loses time, and production efficiency is low.
For meeting the demand of international market to the white acrylic bathtub back side (FRP layer) different colours, applicant sprays green FRP technique to the white acrylic bathtub back side and researches and develops.
Summary of the invention
The object of the invention is to provide a kind of white acrylic bathtub back side green FRP one-shot forming technique, on the basis of assurance product quality, enhances productivity.
To achieve the above object of the invention, the present invention solves by following technical proposals:
1. the green FRP one-shot forming technique in the white acrylic bathtub back side, at least comprises the steps:
The first step, according to bathtub die modeling plastics sucking moulding, completes white acrylic bathtub plastics sucking moulding part with the white acryl plates of high concentration mill base, wherein, uses high concentration mill base acryl plates can reduce sheet material light transmittance;
Second step, green resin batching, its formula is by weight: unsaturated polyurethane resin 50%; Calcium carbonate 50%, green mill base adds and makes green resin by 1% of weight resin;
The 3rd step, white acrylic bathtub plastics sucking moulding part is tipped upside down on and on shoe last or hat block type frame, carries out green resin and add fibrolaminar spraying, described green resin need to heat in agitator, by spray gun, first described green resin is evenly sprayed to white acrylic bathtub bottom to 2mm thickness again, place bathtub and strengthen base plate, again to the described green resin of the comprehensive spraying in the white acrylic bathtub profiled member back side and fiber, spraying evenly, to green resin and fiber layer thickness be 3～4mm, by manually pushing away roller compaction, complete the green FRP spraying in the white acrylic bathtub back side again;
The 4th step, after fully solidifying, cuts, shaping completes production after the green FRP spraying in the white acrylic bathtub back side, generally solidifies 2 hours.
Appearance test is carried out in white acrylic bathtub inner side, and the method for inspection is: by the visual inspection of 500～700mm distance, white acrylic bathtub surface does not have the green marking, does not wear look phenomenon, for qualified.
On such scheme basis, can the above-mentioned first step in, at described high concentration mill base for add 2.5% pigment paste in white acryl plates.
On such scheme basis, in the 3rd step, green resin need to be heated to 45～50 ℃ in agitator.
Superiority of the present invention is: adopts green resin and spraying coating process of fiber, not only can guarantee product quality, and improving production efficiency greatly.
Accompanying drawing explanation
Fig. 1 is the product cross sectional representation that the present invention makes;
Attached number in the figure explanation:
1---white acrylic plastics sucking moulding part;
2---green resin adds fibrage;
3---bathtub is strengthened base plate.
The specific embodiment
Below in conjunction with Figure of description, the present invention is further described.
The green FRP one-shot forming technique in the white acrylic bathtub back side, comprising:
The first step, is used the white acryl plates of high concentration mill base to carry out according to bathtub die modeling plastics sucking moulding, completes the pigment paste that adds 2.5% left and right in white acrylic bathtub plastics sucking moulding part 1(sheet material).
Second step, green resin batching, is: unsaturated polyurethane resin 50% by weight percentage; Calcium carbonate 50%, then add 1% green mill base of weight resin.
The 3rd step, the white acrylic bathtub plastics sucking moulding part completing in the first step is tipped upside down on and on shoe last or hat block type frame, carries out green resin and add fibrolaminar spraying, wherein, green resin need to be heated to 45～50 ℃ in agitator, by spray gun, first evenly spraying to white acrylic bathtub bottom is 2mm thickness, place bathtub and strengthen base plate 3, the spraying green resin whiter acrylic bathtub plastics sucking moulding part 1 back side being carried out in all directions adds fiber, spraying evenly, adding fibrage 2(FRP to green resin) thickness is 3～4mm, again by manually pushing away roller compaction, complete the green FRP spraying in the white acrylic bathtub back side.
The 4th step, white acrylic bathtub back side green resin adds the green FRP of fibrage 2() after spraying, treat fully to solidify for 2 hours, cut shaping and complete production.
If needed, can carry out appearance test to white acrylic bathtub inner side, by the visual inspection of 500～700mm distance, white acrylic bathtub surface does not have the green marking, without what wear look phenomenon, is qualified products.
