Technical field
The present invention relates to one and there is electrostatic-proof function glass fiber reinforced plastics product and preparation method, there is this structureGlass fiber reinforced plastics product can effectively eliminate the static charge accumulation in goods use procedure, reach well anti-Electrostatic efficiency.
Background technology
Fiberglass is owing to having the physical property of a lot of excellences, therefore in building materials, electronics, electric power, boatThe fields such as sky and space flight have obtained application more and more widely. As a large amount of in started in power industry productAdopt the good glass steel shell of durability as shell. But glass steel shell easily produces static and stagnantElectrical phenomena, therefore requires these glass steel shell surfaces should have electrostatic-proof function.
At present, the research that preparation has an electrostatic-proof function glass fiber reinforced plastics product mainly concentrates on two aspects:The one, adopt carbon fiber to replace glass fibre and prepare fiberglass, because carbon fiber has electric conductivity, thereforeObtain the lower fiberglass of sheet resistance; The 2nd, the tree that adopts electric conductivity colloid to replace fiberglass to useFat, glass fibre and conductive rubber form fiberglass, and its electric conductivity is obtained by conductive rubber. Above-mentionedThere are following problems in two class methods: one is that carbon fiber is compared with glass fibre, too expensive,Therefore be only applicable to the manufacture of high-end goods; The second conductive rubber using, major part is by carbon dustOr other metal fine powders add in resin and obtain, for obtaining desired electric conductivity, the electric conductivity addingPowder quantity is larger, and this is easy to produce the decline of colloidal property. Meanwhile, above-mentioned two class methods institutesThe product colour great majority of glass fiber reinforced plastics product of preparation are dull black, and this has affected goods greatlyThe scope of application.
Summary of the invention
Problem and defect that object of the present invention exists in order to overcome prior art, provide one to have anti-Electrostatic function glass fiber reinforced plastics product and preparation method, the present invention makes full use of the glass fibers of laying in fiberglassTie up, can form the network structure of a connection, its surface is carried out, after metalized, effectively carryingThe electric conductivity of high fiberglass. Owing to adopting the technological means of sputter coating, fiberglass surfacing shapeBecome thin metal conducting layer, therefore its production cost is very low, simultaneously for the performance of fiberglass itself notCan exert an influence.
Object of the present invention is achieved through the following technical solutions:
One has electrostatic-proof function glass fiber reinforced plastics product, it is characterized in that being made up of following component, eachComponent is in mass parts:

(1) adopt physical sputtering method to obtain at fiberglass surfacing deposition one deck conductiving metal coatingElectric conductivity glass fibre;
(2) at die surface brushing releasing agent, after releasing agent is dry, by the resin of 60-90 part,1-3 part initator, 120-230 part inorganic filler mixing preparation resin glue, be coated with resin adhesive liquidBrush die surface, spread immediately one deck electric conductivity glass fibre, with hairbrush by electric conductivity glass fibreCompacting, makes electric conductivity glass fibre gel content even, discharges bubble;
(3) after ground floor electric conductivity glass fiber resin glue condenses, then in ground floor electric conductivityBrushing resin adhesive liquid on energy glass fibre, proceeds second layer glass fibre and lays, and successively sticks with paste thereafterSystem pastes after 2~3 layers, until desired thickness at every turn; From every layer of later glass used of the second layerFiber is common glass fibre; 48h solidifying and setting at normal temperatures, the demoulding obtains having antistatic meritCan glass fiber reinforced plastics product. Its instructions for use of demoulding backsight, carries out post processing to it, as used polishing machine to itCarry out surface finish etc.
Described physical sputtering method is magnetron sputtering, hot evaporation or laser deposition.
The conducting metal of fiberglass surfacing deposition one deck conductiving metal coating be gold, silver, aluminium, copper orIron.
The concrete technology parameter of described physical sputtering method is as follows: vacuum is less than 1.0 × 10-3Pa,Sputtering pressure Ar=1.0Pa, sputtering power 80W, substrate temperature is 397K, sputtering time 20min.
The present invention makes full use of the glass fibre of laying in fiberglass, can form the network of a connectionStructure, carries out after metalized its surface, will effectively improve the electric conductivity of fiberglass. Owing to adoptingBy the technological means of sputter coating, form thin metal conducting layer at fiberglass surfacing, therefore it is rawProduce cost very low, can not exert an influence for the performance of fiberglass itself simultaneously.
