Description
Technical Field
The invention relates to the technical field of molded plates, in particular to a glass fiber cloth reinforced transparent molded plate and a processing technology thereof.
Background
The molded plate is a nontoxic and highly transparent thermoplastic engineering plastic, has good impact resistance, electrical property, acid resistance and alkali resistance, and can be widely applied to the fields of decoration, automobile products, electronic products and the like.
At present, most of common molded plate materials take epoxy resin as a matrix, and although the epoxy resin has easy processability and excellent mechanical properties, the epoxy resin has some problems in specific use, such as poor flame retardance, poor thermal stability, low wear resistance and the like, which all limit the use of the epoxy resin in the field of molded plates.
The phenolic resin has the characteristics of good mechanical property, strong thermal stability, high temperature resistance and the like, and is often used as a flame retardant material and a corrosion resistant material, but when the phenolic resin is applied to a molded plate, the required performance of the molded plate cannot be met.
Therefore, in order to solve the above problems, it is important to invent a transparent molding plate reinforced based on glass fiber cloth.
Disclosure of Invention
The invention aims to provide a glass fiber cloth reinforced transparent molded plate and a processing technology thereof, and aims to solve the problems in the background art.
In order to solve the technical problems, the invention provides the following technical scheme:
the method comprises the following steps:
a: adjusting the aqueous solution of the silane coupling agent by using acetic acid to obtain a pretreated silane coupling agent, ultrasonically dispersing nano titanium dioxide in a toluene solution, heating, adding the pretreated silane coupling agent, filtering, extracting, drying, and uniformly mixing with an aqueous solution of sodium dodecyl sulfate to obtain modified titanium dioxide;
b: uniformly mixing modified titanium dioxide, water and ammonium bicarbonate, adding hydroxypropyl methyl cellulose and bis (2-ethylhexyl) peroxydicarbonate, uniformly mixing, adding polyvinyl chloride, adding acetone thiosemicarbazone, drying, adding calcium carbonate and an auxiliary agent, and extruding by a double-screw extruder to obtain modified polyvinyl chloride;
c: dissolving phenol and alkali lignin in water, and adding paraformaldehyde and sodium hydroxide solution for three times to obtain alkali lignin-phenolic resin;
d: dissolving carbon nanofibers in an acetone solution, carrying out ultrasonic reaction, cooling, carrying out ultrasonic reaction again, spraying the mixture on the surface of glass fibers, uniformly mixing the mixture with bisphenol A epoxy resin, and adding 4, 4' -diaminodiphenyl sulfone to obtain modified epoxy resin;
e: mixing silicon carbide and silicon powder, grinding into powder, uniformly mixing silicon nitride and lignin, adding water, adding the ground powder, uniformly mixing, adding water, and sintering to obtain silicon carbide-silicon powder;
s2: uniformly mixing silicon carbide-silicon powder, modified polyvinyl chloride, alkali lignin-phenolic resin, a flame retardant and modified epoxy resin, and adding hexamethylenetetramine and a solvent to obtain a resin glue solution;
s3: respectively soaking the glass fiber cloth and the carbon fiber cloth in the resin glue solution, taking out and air-drying;
s4: and stacking a layer of glass fiber cloth and a layer of carbon fiber cloth in a multi-layer manner, and performing hot-pressing compounding to obtain the molded plate.
Preferably, the method comprises the following steps:
