Technical Field

The invention relates to the technical field of glass fiber reinforced plastic product production, in particular to pearlescent glass fiber reinforced plastic.

Background

The glass fiber reinforced plastic is a composite material with glass fiber and its product as reinforcing material and synthetic resin as base material. The glass fiber reinforced plastic has the characteristics of corrosion resistance and light weight, is widely applied in various fields, and along with the increasingly wide application field of glass fiber reinforced plastic products, people also put forward higher and higher requirements on the appearance of the glass fiber reinforced plastic products.

Disclosure of Invention

Aiming at the technical problems, the invention provides the pearlescent glass reinforced plastic, the surface of the glass reinforced plastic product can maximally reflect the light rays incident to the surface of the glass reinforced plastic product through the reflection and refraction of the pearlescent powder on the light rays, so that the surface of the glass reinforced plastic product can obtain better glossiness, the glass reinforced plastic product with more characteristics and more bright appearance can be obtained, the mica pearlescent powder and the unsaturated resin have better compatibility, the problem of easy color change does not exist, and the hardness, the weather resistance and the yellowing resistance of the glass reinforced plastic product are not influenced while the mica pearlescent powder has good pearlescent color.

In order to achieve the purpose, the invention adopts the following technical scheme:

the pearly-luster glass fiber reinforced plastic comprises a substrate layer and a gel coat layer arranged on the substrate layer, wherein the substrate layer is composed of the following raw materials in parts by weight: 40-70 parts of unsaturated resin, 0.2-1 part of accelerator, 2-3 parts of curing agent and 30-60 parts of fibrofelt, wherein the gel coat layer is prepared from the following raw materials in parts by weight: 100 parts of unsaturated resin, 1-10 parts of mica pearl powder, 0.5-25 parts of color paste, 2-3 parts of curing agent and 0.2-1 part of accelerator.

Preferably, the pearlescent glass fiber reinforced plastic comprises a substrate layer and a gel coat layer arranged on the substrate layer, wherein the substrate layer is composed of the following raw materials in parts by weight: 70 parts of unsaturated resin, 1 part of accelerator, 3 parts of curing agent and 30 parts of fiber felt, wherein the gel coat layer is prepared from the following raw materials in parts by weight: 100 parts of unsaturated resin, 1 part of mica pearl powder, 25 parts of color paste, 3 parts of curing agent and 0.2 part of accelerant.

Preferably, the unsaturated resin is an unsaturated polyester resin.

The beneficial technical effects of the invention are as follows: the mica pearl powder is added into the gel coat layer, the mica pearl powder is a special pearl pigment formed by covering a layer of metal oxide on the surface of mica and then covering a layer of other transparent pigments, and the light rays incident on the surface of the glass fiber reinforced plastic product can be maximally reflected by the surface of the glass fiber reinforced plastic product through the reflection and refraction of the pearl powder on the light rays, so that the surface of the glass fiber reinforced plastic product obtains better glossiness, the surface of the glass fiber reinforced plastic product is endowed with pearl gloss, and the glass fiber reinforced plastic product also has attractive color of the transparent pigment, so that the glass fiber reinforced plastic product with more unique and brighter appearance can be obtained, and the glass fiber reinforced plastic product is diversified; mica pearl powder is added into the gel coat layer, so that the gel coat layer has a physical structure similar to pearl: the inner core is mica with low optical refractive index, the outer layer is coated with metal oxide with high refractive index, such as titanium dioxide or ferric oxide, and the pearlescent pigment is uniformly dispersed in the gel coat, so that a better pearlescent effect is embodied; the mica pearl powder has better compatibility with unsaturated resin, has no easy color change problem, has good pearl color, and simultaneously has no influence on the hardness, weather resistance and yellowing resistance of the glass fiber reinforced plastic product.
