Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-3, in an embodiment of the present invention, an epoxy flame-retardant prepreg fabric includes five satin fiberglass cloth composite material layers 1 and a flame-retardant epoxy adhesive material layer 2, wherein the flame-retardant epoxy adhesive material layers 2 are respectively connected to two side surfaces of the five satin fiberglass cloth composite material layers 1.
The thickness of the flame-retardant epoxy prepreg is 0.7-0.8 mm, and the width of the flame-retardant epoxy prepreg is 5-1300 mm.
All inlayed stainless steel metal mesh layer 3 in the fire-retardant epoxy glue bed 2, 0.1mm is selected to the thickness of stainless steel metal mesh layer 3, and stainless steel metal mesh layer 3 goes up the semicircular arch 4 of the forming a plurality of, the arch 4 of five satin weave glass fiber cloth combined material layer 1 both sides is evagination respectively, increase product toughness and tensile strength through stainless steel metal mesh layer 3, stainless steel metal mesh layer 3 can guarantee that fire-retardant epoxy glue bed 2's distribution is even in addition, because inside inlayed stainless steel metal mesh is like filling, can improve the fire-retardant epoxy of liquid and scribble time tension.
The edge of the five-satin glass fiber cloth composite material layer 1 is bent into a wavy shape 6, and the outer side edge of the wavy shape 6 (also the outer side edge of the five-satin glass fiber cloth composite material layer 1) is vertically upward or vertically downward, so that the edge of the epoxy flame-retardant prepreg cloth is protected.
The manufacturing process of the epoxy flame-retardant prepreg cloth comprises the following specific process steps:
(1) preheating the component A of the epoxy resin in an oven to 110 ℃ for melting;
(2) mixing the component A of the epoxy resin with the component B of the epoxy resin, heating to 120 ℃, stirring, revolving for 20 frequencies, rotating for 10 frequencies, mixing and heating to generate a mixer;
(3) adding the fire retardant, titanium dioxide and white carbon black into the epoxy resin mixed in the step (2), fully stirring and cooling, wherein the stirring time is 1 hour, and revolution is carried out at 25 frequencies, and rotation is carried out at 15 frequencies;
(4) when the mixed materials are cooled and uniformly stirred, the temperature is reduced to 70 +/-2 ℃, a premix coupling agent, dicyandiamide and urea are added to continue stirring for 15 minutes, revolution is carried out at 30 frequency, and rotation is carried out at 20 frequency;
(5) the production method comprises the following steps of adjusting a gluing machine set, producing epoxy flame-retardant prepreg by adopting the gluing machine set, respectively coating a layer of flame-retardant epoxy glue material on each of two sides of a five-satin glass fiber cloth composite material layer 1 during actual coating, placing a stainless steel metal mesh layer 3, and then coating a layer of flame-retardant epoxy glue material, thereby sequentially realizing structural compounding of the two sides;
(6) and (4) inspecting the produced epoxy flame-retardant prepreg, and labeling the epoxy flame-retardant prepreg qualified in inspection.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
