Description
Technical field
The invention belongs to field of air filtration, are related to a kind of air filter paper, more particularly to a kind of light-high-strength glass
Fiber filter paper and preparation method thereof.
Background technology
All-glass paper/felt has fabulous fire-retardant, sound-absorbing, heat-insulating property, is provided simultaneously with the advantages that light, inexpensive.Mesh
Before, all-glass paper is widely used in fields such as household decoration, building external wall energy-saving heat preservation, air purification.Glass
Fiber air filter paper is the key components of filtering element for air filter, and the performances such as thickness, grammes per square metre, intensity, rigidity determine
The performance of air filter.Glass fibre air filter paper is mainly used in the air filtration under particular surroundings, will be in air
The oil molecule of diffusion stops by air filting material or is trapped in that outside, protection are polluted the space of environment by oil molecule.Due to
Filter is that glass fibre air filter paper is converted into filter core by discounting, machine, and outline border is fixed on by hot melt adhesive is fixed-type
On, therefore the thickness of glass fibre air filter paper, intensity must satisfy the requirement of filter applying working condition, and filter is made to be suitble to
In different wind speed, flow, it is suitable for different environment temperature requirements.
Disclosed on the Chinese patent of Publication No. CN103721477 A a kind of high-strength glass fiber air filter paper and
Preparation method, the high-strength glass fiber air filter paper are made of glass fibre and adhesive, and glass fibre is put down at one
Uniform random distribution in face forms micron-sized gap between multiple glass fibres, and adhesive wraps the friendship between glass fibre
It knits on a little, forms netted joint face.Glass fibre is made of glass chopped silk and/or glass fibre cotton, and adhesive is by nothing
Machine silica gel or colloidal alumina or combination thereof overcome existing all-glass paper intensity low and high temperature filter effect bad equal scarce
Point, this kind of high-strength glass fiber air filter paper can be used as the heat insulating element in fields such as building, machinery, thermal energy or heat-insulated fill out
Material, can be used for air cleaning unit.But filter paper unit weight prepared by this method is larger, and filter efficiency is poor.
A kind of high-strength glass fiber air filter paper is disclosed on the Chinese patent of Publication No. CN102505554A,
The organic fibers such as terylene, aramid fiber, acrylic fibers, polypropylene fibre, polyvinyl, fibre length preferably 3~15mm, fibre diameter are added in organic fiber
It is preferred that 0.3~5dan.The intensity and deflection under glass fibre air filter paper normality are not only increased, while being dispersed in paper
Organic fiber in page is melted into binder at high temperature, compensates for strong because what is lost after acrylic adhesive pyrolytic
Degree.The high resiliency of organic fiber simultaneously, ensure that the gas permeability and filter efficiency of air filter paper, it is ensured that manufactured highly effective air
Filter can at a temperature of more than or equal to 250 DEG C continuous work.But this design still remains that filter paper unit weight is larger to ask
Topic causes equipment energy consumption higher during use.
Invention content
The purpose of the present invention overcomes the shortcomings of the prior art, provide a kind of light-high-strength glass fiber filter paper and its
Preparation method.By using two-component hollow glass fibre as the material for making filter material, bicomponent fibers nature had both been played
The characteristic of bending, mutually button solution so that it is difficult to slide between fiber, the stability of filter paper is improved, in conjunction with the viscous of adhesive
Knot acts on, and the intensity maximum of filter paper improves, in addition, bicomponent fibers are made hollow form, has both alleviated the weight of filter material itself
Amount, but also the specific surface area of filter material greatly increases, filter efficiency is greatly improved.
To achieve the purpose of the present invention the technical solution adopted is that：A kind of light-high-strength glass fiber filter paper, by double groups
Part hollow glass fibre is formed with adhesive, it is characterised in that and the two-component hollow glass fibre hollow rate is 0.60~
0.95, average diameter is 0.8~7.2 μm, draw ratio is 16~78, and section is one kind or two in round either ellipse
The mixing of person, the two-component glass fibre form mixing after two furnaces respectively by the glass raw material of two kinds of components
Liquid, then be blown wire drawings through 1450~1550 DEG C of thermal-flames and formed, wherein the first component glass raw material coefficient of expansion is 4.5 ×
10-6~6.0 × 10-6/ DEG C, ingredient is calculated by mass to be：45~76%SiO2, 6~22%Al2O3, 6~20%MgO, 0~3%
CaO, 0~2%FeO, 0~2%Na2O+K2O；Second of component glass raw material coefficient of expansion is 8.0 × 10-6~10.0 × 10-6/
DEG C, ingredient is calculated by mass to be：45~76%SiO2, 6~22%Al2O3, 6~20%MgO, 0~3%CaO, 0~2%FeO, 8
~22%Na2O+K2O。
The first component glass raw material accounts for 30%~60%wt of the glass raw material of two kinds of components in the glass fibre,
Wherein preferably 45%~55%.
The adhesive position is in phenolic resin adhesive or melamine and urea-modified phenolic resin adhesive
One kind, wherein it is preferred that melamine and urea-modified phenolic resin adhesive.
The invention also discloses a kind of preparation methods of light-high-strength glass fiber filter paper, it is characterised in that including following
Step：
(1) glass fibre is added in beater and is disperseed, using water as dispersant and solvent, glass fibre raw material
It is dissociated into cotton pulp；
(2) cotton pulp, aqueous solution, which are delivered in mud pit, stirs and carries out slagging-off processing, and the solid content control in slurry exists
3~7, air content is controlled 3~6% for 0.25~0.6%wt, pH control；
(3) mixed slurry stirred evenly is delivered on the filter screen of twin-wire press and is manufactured paper with pulp, thickness control exists
Between 0.1~2mm, the gains that will manufacture paper with pulp carry out vacuum suction water removal and ground paper are made after squeezing；
(4) adhesive is diluted to 10~40 times, be equably sprayed on glass fibre ground paper, extra adhesive is by taking out
Suction box aspirates, and is come back to after knockout drum detaches in cycle glue tank；
(5) will sizing treated that glass fibre ground paper enters baking oven under the conditions of 260~300 DEG C, dry 1~5min,
Obtain light-high-strength glass fiber filter paper.
Advantageous effect possessed by the present invention is：1. lightweight, as a result of the structure of hollow glass fibre, therefore filter paper
Under conditions of ensureing identical filter efficiency, quality lighter this allows for filter paper and applies to when on removable facility oil consumption more
It is few, energy saving, environmental protection；2. intensity is high, since fiber uses two-component form, mutually winds between fiber, to buckle solution even closer, make
The raising for obtaining the intensity maximum of filter paper, increases its service life.
