Abstract

The present invention a kind ofly makes the substrate glass steel with thermosetting resin, mixes such as MgCO 3, Al 2O 3, CaCO 3Deng the electroplated glass fiber reinforced plastics of additive, after plating, make it both to have kept the distinctive physics of glass steel, chemical property, have the character of metallic substance conduction, magnetic conduction, surface luster again.In industrial structure, medical machinery, communal facility, large-scale sculpture, industrial art, be used for replacing the member that needs fully with metal casting, very gratifying prospect is arranged.

Description

The invention relates to glass fiber reinforced plastic which can be used for electroplating.

Until now, the domestic glass Fiber Reinforced Plastic (FRP) industry is still in the infancy, and the original process technology is mainly applied, namely the simple and crude products are formed by hand pasting fiber cloth and polyester resin. Although the production patents of Filon plates and Silar unsaturated polyester are introduced from abroad in recent years, the processing and manufacturing process and technology of FRP have great progress, and FRP starts to replace steel and iron in many occasions of industrial structures and various industries of automobile and ship building with excellent mechanical property and chemical property, and is applied. However, since FRP itself lacks metallic texture, its use value and application field are limited to various degrees.

The above prior art is reflected in the glass fiber reinforced plastic processing performance published in 1974 of the Chinese architecture industry Press and the glass fiber reinforced plastic/composite material in pages 36 to 44 of the first period of 1988 of the glass fiber reinforced plastic industry in recent years and the near situation and prospect of the glass fiber reinforced plastic for domestic automobiles in pages 3 to 5 of the second period of 1988.

The invention aims to develop a glass fiber reinforced plastic which can be used for electroplating, so that the glass fiber reinforced plastic not only maintains the specific physical and chemical properties of the glass fiber reinforced plastic, but also has the properties of metal materials such as electric conduction, magnetic conduction and surface gloss.

The technical scheme of the invention is that thermosetting resin is used as matrix glass fiber reinforced plastic, and an additive is doped in the manufacturing process of the thermosetting resin, namely, one kind of additive is dispersed in the resin and is subjected to roughening treatmentAn additive which is easily dissolved to form a roughened surface. The roughening treatment can be carried out using a sulfuric acid solution without the need for severely contaminated chromic acid. The resin used comprisesEpoxy resins, polyester resins and phenolic resins. The additive is mainly composed of metal elements of the first, second and third main groups of the periodic table of chemical elements, salts or oxides of a part of transition metal elements and certain acids, such as: MgCO3、AL2O3、CaCO3And the like. Such additives react with acids as follows.

When MgCO is used3The method comprises the following steps:

when using AL2O3The method comprises the following steps:

similar reactions are also possible with other inorganic salts or oxides, and these reactions can be carried out in a very short time.

Because the reaction speed of the organic resin and the acid is much slower, in the coarsening process, the additive is quickly dissolved out from the resin framework to form countless micropores, and hundreds of micropores can reach about 1-2 u on the area of 1 square centimeter. It is these micro-holes that constitute a roughening effect similar to ABS plastic. Therefore, the glass fiber reinforced plastic suitable for electroplating can be prepared by selecting proper additives to be mixed into the resin.

The invention has the advantages that the glass fiber reinforced plastic prepared by the technical scheme has obvious physical and chemical properties of novel composite materials and basic characteristics of nonferrous metals after being electroplated. The glass fiber reinforced plastic can be used for replacing components which completely need to be cast by metal in industrial structures, medical machinery, public facilities, large-scale sculptures and industrial arts, has very promising prospect, and can be conveniently implemented by adopting a traditional processing method, so that the glass fiber reinforced plastic has the characteristics of simple equipment, advanced technology, strong practicability, high economic value and the like, and is ideal platable glass fiber reinforced plastic. The following examples are further illustrative.

Example 1: the epoxy resin glass fiber reinforced plastic can be electroplated.

Resin component (c): epoxy resin 100g

Dibutyl ester 15g

Ethylenediamine (8 g)

Additive: MgCO330g

The glass fiber cloth is used as reinforcing material, and the characters for large signboard in the shop are treated by the following process, so that the characters for signboard with gold-like metal appearance can be obtained. The process flow is as follows:

coarsening: 30% H2SO4

The temperature is 30-40 DEG C

The time is 15 to 30 minutes

Sensitization: SnCL240g/L

HCL 40mL/L

And (3) activation: PaCL20.5g

HCL 3-5mL

1000mL of water

Chemical copper plating: CaSO47g/L

Sodium potassium sulfate 20g/L

NaOH 5g/L

Formaldehyde 25mL/L

Electroplating copper and then electroplating imitation gold copper-zinc alloy. The process can be summarized as follows: modulation-platable glass fiber reinforced plastic → molding → coarsening → sensitization → activation → chemical plating → electroplating. After coarsening, each process requires a strict water wash.

Example 2:

the resin formula is as follows: no. 618 epoxy resin 100g

Triethylene tetramine 15g

Propylene oxide butyl ether 10g

Additive: MgCO350g

Benzoyl peroxide 0.5g

Additive: AL2O340g

The glass fiber cloth is used as a reinforcing material, the resin is used for casting the artistic desk lamp, the electroplating process is carried out according to the embodiment 1, acid bright copper is thickly electroplated after electroless copper plating, and the antique copper artistic desk lamp holder can be manufactured.
