Add cobalt water to the resin and stir slowly, add talc powder, the ratio is half of the resin and talc powder, only a few bottles of cobalt water are enough, then add 2 bottles of curing agent, stir well, the resin can be a little more in the first pass, It ’s best to dilute it, brush it in the mold, wait for 80% to dry, brush it a second time, add more talcum powder, thicker, brush it up, and then paste the cut piece of fiberglass cloth to each position. Paste it, and then apply it with resin without talc powder (cobalt water and curing agent are added), wait for 70% to dry, cut off the excess glass fiber outside the clamping line, and cut it dry before cutting. Already.
Then apply a thick layer of resin on the mold clamping line, close the mold, wait to dry, then open the mold, take out the Fiberglass, and finish.
Take the Fiberglass out, repair the mold line, wash the surface with caustic soda water, and polish it with water. If you want to retain the texture, you don’t need to polish it. Spray a layer of white epoxy primer. Put small holes on the surface to make up with putty. Then sand, the surface needs to be rough or not.
An important issue in Fiberglass sculpture molding is to strengthen the structure. Generally, metal profiles are used to strengthen the materials, and metal profiles are welded to form the internal skeleton of the sculpture. During molding, the metal skeleton is gradually buried in the sculpture.
Based on this, the rigidity and strength of the Fiberglass sculpture are increased, and its service life is increased. Finally, the glass fiber reinforced plastic sculpture is assembled with a metal framework, and the mold is filled with surface putty. Chopped felt is laid. Gingham is laid.
The sculpture surface is usually more complicated, and it should be specially treated on the craft layer. The place where the fiberglass felt is difficult to place should be filled with resin containing short fibers first, and then the fiberglass chopped felt and gingham should be laid.
The length of the glass fiber in the resin putty for the sculpture surface is preferably 10mm. The proportion of the resin putty for the sculpture surface is polyester resin glass fiber CaCO3 filler pigment. The amount of cobalt methyl ethyl ketone naphthalate is 1002010022-40.5-4.
The last step is post-processing, then spray epoxy primer, and then paint for effect, and finally spray protective varnish, the glass fiber reinforced plastic sculpture process is completed.
On the one hand, the later treatment of Fiberglass sculpture is to repair some defects of the product after demolding, and more importantly, to create the appearance effect. The appearance effect often used is imitation copper and imitation bronze. The key is to prepare color paste.
1. The surface is scraped and polished with resin putty.
2. Effect processing. Through the methods of painting, spraying, distressing, and gold pasting, you can achieve the effects of imitating gold, silver, copper, antique copper, imitating jade, imitating stone, etc. For example: antique copper, there are dozens of methods and effects, color Natural and full, the copper texture is strong, the patina is real, and the patterns and textures are very delicate, which cannot be achieved by metal products.
Among them, the amount of molybdenum chromium red phthalocyanine blue blue phthalocyanine dibutyl copper gold powder is 550.30.7240200, and the amount of chrome yellow phthalocyanine blue molybdenum chromium red dibutyl copper gold powder is 620.351803003.
Combining advanced scientific and technological methods, Bosong Beijing Sculpture Company has perfectly presented a series of methods such as titanium plating, nano electroplating, and metal spraying in the glass steel sculpture process, which has been widely praised by customers and accepted the test of quality.
Using glass fiber reinforced plastic technology, you can quickly save the clay sculptures. Therefore, Fiberglass sculpture has become a landmark of squares and playgrounds in living quarters, but Fiberglass sculpture is not a simple matter and requires a certain production process and process.
