Abstract
The utility model relates to a glass fiber continuous acupuncture combination mat, which consists of an upper glass fiber precursor fiber carpet, a lower glass fiber precursor fiber carpet, and a middle carpet, wherein, the upper glass fiber precursor fiber carpet and the middle carpet, and the lower glass fiber precursor fiber carpet and the middle carpet are respectively combined into a whole by a lower needling process and an upper needling process. The glass fiber continuous acupuncture combination mat of the utility model has the advantage of the large porosity of a needle felt, thereby being beneficial for resin to diffuse, flow and imbue; moreover, the carpet surface of the glass fiber continuous precursor fiber can increase the surface decorative effect of pultrusion glass fiber reinforced plastic materials, meanwhile, the newly added roving cloth middle carpet on which glass fiber is added can also increase a strength requirement that the glass fiber continuous acupuncture combination mat of the utility model is taken as reinforcing material in a pultrusion process, therefore, the glass fiber continuous acupuncture combination mat of the utility model can be widely applied to a glass fiber reinforced plastic pultrusion process so as to be taken as the reinforcing material of the glass fiber reinforced plastic, and also can be widely applied on the insulated winding of a transformer.
Description
Technical field
The utility model relates to a kind of glass fibre continuous needle composite felt.
Background technology
Fiberglass needled mat is mainly used in filtering material, heat-insulation and heat-preservation material and strengthens three aspects of thermoplastic sheets (GMT).Its main feature is voidage height (can reach 70%-80%), has therefore just had the function of aspects such as filtration, insulation, sound insulation, damping, and glass fibre itself is nonflammable in addition, and is high temperature resistant, therefore has fire-retardant function again.But glass is through after the acupuncture, because loss of strength big (losing the 60-70% of former intensity approximately), therefore doing the filtering material time spent must be with glass fibre cotton acupuncture on the higher base fabric of intensity.And during as insulation, acoustic material, because no powerful requirement, so need not use base fabric.Existing fiberglass needled mat because of acupuncture after loss of strength bigger, therefore can not be applied in the pultrude process of requirement of strength.
Summary of the invention
The problem that is exactly in the pultrude process that existing fiberglass needled mat can not be applied to requirement of strength to be solved in the utility model.
For solving the problems of the technologies described above, the utility model on non-twist checked cloth, makes it to keep Nomex voidage height (voidage also can arrive 60-70% greatly), the characteristics that are easy to resin flows, spread and soak into the acupuncture of glass fibre continuous strand; Can keep non-twist checked cloth advantages of high strength again.
The utility model is made up of upper glass fiber precursor carpet veneer, lower-glass fiber precursor carpet veneer and intermediate layer, and it is one that upper glass fiber precursor carpet veneer and intermediate layer, lower-glass fiber precursor carpet veneer and intermediate layer are passed through following needling process and last pin needling process compound respectively.
Above-mentioned intermediate layer is the non-twist checked cloth of glass fibre.
Because continuous strand will exceed about one times than chopped strand intensity, but the acupuncture resistance ratios chopped strand of continuous strand will exceed about 50%, and the acupuncture resistance is big, and it is dark not only to be difficult for thorn, and broken needle easily.Given this, the utility model has adopted the structure of above-mentioned similar " sandwich ", i.e. two-layer employing continuous strand carpet veneer up and down, and the middle non-twist checked cloth of layer of glass that increases, adopting needling process compound between three layers up and down is one.Like this, the utility model has not only kept the characteristics of Nomex voidage big (voidage is about 60-70%), help resin diffusion, flow and soak into, and the carpet veneer surface of glass fibre continuous strand can also improve the surface decoration effect of dragging and squeezing glass fiber reinforced plastics material, and that sets up simultaneously adds the non-twist checked cloth of glass fibre intermediate layer and can also increase the requirement of strength of the utility model as the reinforcing material in the pultrude process.Therefore, the utility model can be widely used in the fiberglass pultrude process, as the reinforcing material of fiberglass, also can be widely used on the insulation winding of transformer.
The utility model adopts existing needling process to be composited, and the main production parameter is as follows:
The thorn machine is 300-400 rev/min under the EMNS-WR100-450-1000
(alkali-free continuous needle-checked cloth composite felt) stings 950-1050 rev/min of charging down
450-550 rev/min of main-needling machine (going up the thorn machine)
Throw silk screen band 20-25HZ
Filament throwing roller A 21.5-23HZ
B 25-28HZ
A tow 60-65 bundle
B tow 60-65 bundle
Winder 400-500 rev/min
Illustrate: EMNS is an alkali-free glass fibre acupuncture composite felt, and WR100 is the mass area ratio of checked cloth, and 450 is the mass area ratio of composite felt, 1000 for width be 1000mm.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The production wide cut is 1m, and mass area ratio is 450g/m
2The glass continuous needle composite felt of enhancing pultrusion material:
The glass continuous strand of 110Tex is being transmitted on the guipure through the first road filament throwing roller spreading, spreading 100g/m immediately
2Non-twist checked cloth, through the second road filament throwing roller continuous strand spreading of 110Tex is being transmitted on the guipure again, through acupuncture down and go up acupuncture and make 450g/m
2The glass fibre continuous needle composite felt of forming by upper glass fiber precursor carpet veneer 1, lower-glass fiber precursor carpet veneer 3 and the non-twist checked cloth of glass fibre intermediate layer 2, the needling density of needing machine is 12 pins/cm
2, depth of needling is 8mm.
Claims (3)
1, a kind of glass fibre continuous needle composite felt, it is characterized in that being made up of upper glass fiber precursor carpet veneer, lower-glass fiber precursor carpet veneer and intermediate layer, it is one that upper glass fiber precursor carpet veneer and intermediate layer, lower-glass fiber precursor carpet veneer and intermediate layer are passed through following needling process and last pin needling process compound respectively.
2, glass fibre continuous needle composite felt according to claim 1 is characterized in that described intermediate layer is the non-twist checked cloth of glass fibre.
3, as glass fibre continuous needle composite felt as described in the claim 2, it is characterized in that the non-twist checked cloth 100g/m of described glass fibre
2The non-twist checked cloth of glass fibre.
