Abstract
The present invention relates to a technological method for preparing ultrathin glass wool products with high volume weight, which comprises: ingredients of glass wool are molten into glass metal which can be formed into resin wool felts containing adhesives by spraying adhesives; before the glass wool is shaped by hot pressing, a surface material layer is respectively laid on the upper surface and the lower surface of the glass wool with a ready cut shape; the shape of the surface material layer is corresponding to the shape of the cut glass wool; then the glass wool is shaped by hot pressing. By using the technological method of the present invention, the preparation and production of the ultrathin glass wool products with high volume weight can be realized; the glass wool products in thickness of 3 to 50mm and in volume weight of 24 to 350 kg/m<3> can be processed. With the advantages of stable quality, simple used devices, low cost, wide application range, etc., the technological method can be applied to some using occasions with high requirement for heat insulation.
Description
The present invention relates to the processing method of moulded glass cotton products, refer in particular to a kind of processing method ultra-thin, high volume weight glass fiber products for preparing.
Glass wool is the effectively insulating lagging material, it is little to have density, good springiness, resistance to chemical attack such as does not fire at a series of high-performances, and handling ease is arranged, durable in use, advantage such as with low cost is widely used as lagging material in industry, the complete processing of traditional preparation glass wool goods, the density of its finished product is 16-96kg/m
3, thickness is 15-50mm, can satisfy the general industry purposes substantially.But to some insulation, heat insulation having relatively high expectations and the usage space occasions with limited, for example the automobile steamer in precision optical machinery, the transport facility etc. requires to use unit weight at 96kg/m
3More than, the glass wool goods of thickness below 15mm, prior art can not satisfy these requirements.
The purpose of this invention is to provide a kind of processing method ultra-thin, high volume weight glass fiber products for preparing, the unit weight of its finished product can reach 350kg/m
3, thickness can be as thin as 3mm, uses the use range of widening the glass wool goods, satisfies the use needs of some special occasions.
The object of the present invention is achieved like this:
A kind of processing method for preparing the glass wool goods, it is characterized in that: this processing method comprises in regular turn:
A. the glass wool batching is fused into glass metal, spray glue makes its formation contain the resin cotton felt of binding agent, and its parameter is:
Average fibre diameter≤7mm
Binding agent adhesive rate 6.5%-8%
Slag ball content≤0.3%
B. the upper and lower faces at the glass wool of having cut out shape is respectively laid one deck precoat before hot-forming, and the shape of this precoat is with corresponding through the shape of cutting out cotton glass wool;
C. hot compacting in mould, its processing parameter is:
160-220 ℃ of mould intensification.
In preferred embodiment, this processing method flow process is: the glass wool batching is fused into glass metal, spray glue makes its formation contain the resin cotton felt of binding agent, upper and lower faces at the glass wool of having cut out shape before hot-forming is respectively laid one deck precoat, and the shape of this precoat is with corresponding through the shape of cutting out cotton glass wool; Hot compacting on pressing machine, burr are dismissed in depanning then, and are with glue that the banding around the product is good, the finished product warehouse-in.
Precoat embodiment one, the material of described precoat are the composite glass fiber felt.
Precoat embodiment two, the material of described precoat are tinfoil paper.
Precoat embodiment three, the material of described precoat are the PVC film.
In preferred embodiment, the mould of described hot-forming use is made of the upper and lower die body that inside is provided with nichrome wire.The upper and lower mould of the mould of described hot-forming use is hinged in a side.
The present invention has following actively useful effect:
1. realized preparation production ultra-thin, high volume weight glass fiber products, can process thickness is 3-50mm, unit weight 24-350kg/m
3The glass wool goods.
2. can be processed into the various three-dimensional space shapes that have according to the actual requirements, the glass wool goods of different size satisfy the needs of various different purposes.
3. steady quality carries out hot pressing at the upper and lower faces paved surface bed of material of the resin cotton that contains binding agent, can guarantee that the smooth surface of the glass wool goods after the hot pressing does not fly cotton.
4. use equipment is simple.
5. with low cost.
6. use upper and lower hot-die when the hinged Mould Machining of a side, can not need the applying pressure machine.
Now in conjunction with the accompanying drawings with preferred embodiment.
Fig. 1 shows the embodiment of the heating mould structure that uses in the processing method of the present invention.
The same Fig. 1 of Fig. 2, for upper and lower mould in the hinged embodiment of a side.
Fig. 3 is for going into the hot-forming processing synoptic diagram of mould with processing method production motor car engine insulation plate of the present invention reality hedge example.
The hot pressing die that uses in the processing method of the present invention is made of upper die body 1, lower mold body 2 and sees Fig. 1, and nichrome wire 3 is housed in the upper die body 1, and there is patrix 4 bottom surface, and nichrome wire 5 is housed in the lower mold body 2, and end face has counterdie 6, is equipped with in the diagram counterdie 6 and treats hot pressing glass fiber blanket 7.
The same Fig. 2 of the mold structure of Fig. 3, not existing together is that upper and lower mould 1.4 is hinged with hinge pin 10 in homonymy.The mould of present embodiment need not pressing machine when using.
Patrix 4 among Fig. 3, the shape of counterdie 6 is corresponding with motor car engine insulation plate shape, the precoat 8,9 that is equipped with the compound glass staple fiber batt in the upper and lower two sides of the resin cotton 7 that applies binding agent is to guarantee that the smooth surface of glass wool goods does not fly cotton after the hot pressing, and the technological process of Fig. 3 embodiment is:
1. pack into the nichrome wire 3,5 of 4000w of the negative and positive mould with three-dimensional shape 1,2 that will process, and connect 3,5 with thermopair and temperature control instrument, be installed on the press, through debugging, make mould 1 can with 2 good matched moulds, landing is carried out the intensification of mould and is prepared freely.
