Description
Technical field
The invention belongs to Molding Technologies of Glass Fibre Reinforced Plastics field more particularly to a kind of winding, molding methods of fiberglass.
Background technology
Fiberglass is also referred to as GFRP, i.e. fiber-reinforced plastic, refers generally to glass fiber reinforcement unsaturated polyester, asphalt mixtures modified by epoxy resin
Fat and phenolic resin as matrix resin, make the reinforced plastics of reinforcing material with glass fibre or its product, and appellation is moulded for glass fiber reinforcement
Material, or be fiberglass.
The concept of composite material, which refers to a kind of material, cannot meet requirement, need the material by two or more
It is combined with each other, composition another kind can meet the material of people's requirement, i.e. composite material.For example, single kind of glass fibre, although
Intensity is very high, but is loose between fiber, can only bear pulling force, cannot bear bending, shearing and compression, is also less prone to make solid
Fixed geometry is soft body.If they are bonded together with synthetic resin, can make various with fixed shape
Hard product, can bear tensile stress and bear bending, compression and shear stress.This just constitutes glass fiber reinforcement
Plastic base composite material.Since its intensity is equivalent to steel, and contain glass ingredient, it may have color and luster as glass, shape
The performances such as body, corrosion-resistant, electrical isolation, heat-insulated form this straightaway title " glass in history as glass
Steel ", this noun was proposed in 1958 by former national building materials Ministry of Industry minister comrade Lai Jifa, by building materials system
Expand to the whole nation.The meaning of fiberglass refers to just that glass fibre makees reinforcing material, synthetic resin makees the reinforced plastics of binder, external
Claim fiberglass reinforced plastics.With the development of China's fiberglass cause, as the reinforcing material of plastics base, by glass fibre
It is expanded to carbon fiber, boron fibre, aramid fiber, alumina fibre and silicon carbide fibre etc., far and away, these tencels are made
Reinforced plastics, be some high performance fibre reinforced composites, then this is commonly called as just summarising with fiberglass, consider
To the origin and the development of history, generally use glass fiber reinforced plastics composite material, such a title is just more comprehensive.
The manufacturing process of glass fiber reinforced plastics product mainly has 1 hand paste production method, 2 injection molding method, 3 pressure stochastic distribution at present
5 pultrusion method of 4 die press technology for forming of method and moulded plastic forming technology, since each manufacturing process has the spy of itself
The case where point, enterprise needs the basic condition and production product according to enterprise, to select to determine which kind of process used.
The winding method of fiberglass includes mainly dry method, wet method, semidry method at present, and the implementation result of wherein dry method is best
, but since dry method needs pre-soaking fiber, and the equipment manufacturing cost of pre-soaking fiber is very high, and it is higher to implement cost, is unfavorable for
It promotes the use of on a large scale.
Invention content
The present invention provides a kind of winding, molding method of fiberglass, to solve preimpregnation equipment mentioned above in the background art
The higher problem of cost.
Technical problem solved by the invention is realized using following technical scheme：
A kind of winding, molding method of fiberglass, the forming method include the following steps：
The first step, the preparation of raw material to fiber check whether and is met the requirements first, then in 80 DEG C -120 DEG C of oven
It is inside dried 16-20 hours；
Second step configures glue, weighs first to each component；
Third walks, and checks equipment, opens wrapping machine and dallies, checks running situation；
4th step cleans core model, is first polished mandrel surface with sand paper, then cleaned up with ethyl acetate；
5th step, it is Wrapping formed, glue is poured into glue groove；Then fiber is divided into two parts, a copy of it fiber is passed through
Steeping vat and Extruded roller are crossed, the plurality of fibers of impregnation is then divided into several groups, then by boundling after yarn divider, then press
It being wound according to the line style of setting, when winding, first winds one layer of fiber without dipped glue, then winds the fiber of one layer of dipped glue,
It alternately winds successively, and adjusts gumming device control fiber band glue amount at any time, when winding at any time wipes extra glue off, and sees
The row's of examining yarn situation；Thickness is measured, can be shut down when reaching design requirement；
6th step, solidification, then product is unloaded, cured into curing oven, and temperature is 100-120 DEG C, and the time is that 2-5 is small
When；
7th step, demoulding, core model is extracted.
Fiber includes 20-30 parts of unsaturated polyester resin, 20-30 parts of hydrogen peroxide, potassium oxide 1-3 by ratio of weight and the number of copies
1-3 parts of tungsten hexachloride, 1-5 parts of fire retardant, 2-4 parts of Nano filling, 20-30 parts of glass fibre, the metal packing 1- that part, phenol are modified

In Wrapping formed step, 2 row's infrared lamps are additionally provided with, fiber surface are heated, and ensure fiber surface
Temperature is between 50-60 DEG C.
The linear of winding includes circumferential winding, plane winding, spiral winding.
Beneficial effects of the present invention are：
The technical program makes to immerse the glue on the fiber of glue by alternately winding the fiber of dipped glue and not having the fiber of dipped glue
Liquid penetrates on the fiber for not having dipped glue, and the equipment to eliminate pre-soaking fiber greatly reduces cost, and implementation result is non-
Often, in addition the technical program fibre fractionation proportioning with glue component proportion, be to be obtained most in a large amount of experimental basis
Good scheme, then have increase infrared lamp, it is ensured that the temperature of fiber surface influences processing quality to prevent fibrosclerosis,
To sum up, the technical program implementation result is good, and cost is relatively low, suitable for promoting the use of on a large scale.
