Description
Technical field
The present invention relates to a kind of filter paper, more particularly, to a kind of high temperature resistant type automatically cleaning filter paper, belong to filtering material field.
Background technology
With the high speed development of modernization industry, environmental pollution is seriously threaten life and the health of the mankind, and recent air is dirty
The injury contaminated to human body is particularly evident, and extensive haze weather is attacked repeatedly.Country is to the continuous of quality of air environment attention degree
Improve, PM 2.5 is included to new Air Quality Evaluation system.How pernicious gas in air is reduced using efficient filtering material
Carry out effectively filtering extremely urgent into human body or to the pernicious gas of discharge.In order to be able to realize the purpose of air cleaning, newly
The filtering material of type high-quality progressively turns into the study hotspot of researcher.Because glass fibre has dimensional stability relatively by force, no
Yielding, electrical insulating property is good, anti-medicine is good, and causes glass fibre with the good characteristic such as acid and alkali-resistance, oil resistant, corrosion-resistant
Preferred material as efficient and ultra high efficiency air cleaner, it is adaptable to the application of the air cleaning of every field.But, glass
There is also some shortcomings for fiber：Fiber Aspect Ratio is big, and surface carries electric charge, easily mutually winds and is difficult to separate；Compare on surface
It is smooth, wire-dividing broom purification can not be produced through mashing processing, physical bond is there's almost no between fiber and fiber, is not also formed
The group of hydrogen bond, page can not produce bond strength naturally；Mechanical strength is low, and non-refractory, dust containing capacity septulum are for a period of time
Need to be changed.
The A of Publication No. CN 103556544 Chinese patent provides a kind of high flame retardant glass fibre air filter paper, the height
Alkali-free glass fibre cotton of the flame-retardance fiberglass air filter paper by a diameter of 7~9 μm, a diameter of 0.3~0.4 μm of alkali-free
Glass fibre cotton and bonding sizing material are made；Described a diameter of 7~9 μm of alkali-free glass fibre cotton and a diameter of 0.3~0.4 μm
Alkali-free glass fibre cotton mass ratio is 1: 3.8~4.2；The cohesive sizing material is that acrylic emulsion and halogen-free organophosphorous hydrochlorate fire retardant are mixed
Compound.The surfacing of glass fibre air filter paper, uniform, fire resistance is good.The filter paper that the patent is provided is effectively increased
High-temperature stability, but the filter paper of patent offer can only carry out air filtration and go out, and other industry is not considered specifically, and
Its resistance to elevated temperatures is also caused to have a greatly reduced quality using glass fibre as raw material, its intensity is not high in addition, and dust containing capacity is limited,
Often replacing is needed during use.
The A of Publication No. CN 103721477 Chinese patent provides a kind of high-strength glass fiber air filter paper and its preparation
Method, the air filter paper is made up of glass fibre with adhesive, and described glass fibre is uniform random point in a plane
Micron-sized hole is formed between cloth, multiple glass fibres, adhesive is wrapped on the intertwined point between glass fibre, form netted company
Junction.Glass fibre is by diameter in the glass of glass chopped silk and diameter between 1 μm~10 μm between 6 μm~20 μm
Glass cotton fiber is constituted.Adhesive is formed by inorganic silica gel or colloidal alumina or combinations thereof.The air filter paper is in normal temperature and height
Enough intensity is provided with temperature and excellent gas-liquid separation, liquid-liquid separation ability, can resist wind speed, flow it is multiple
Invasion and attack.Inorganic silicon or colloidal alumina adhesive used in the filter paper that the patent is provided, intensity is not high, cohesive force is not strong, because
This reduces the intensity of integral filter paper, and also causes that its intensity is restricted using glass fibre as raw material, and dust containing capacity is low,
Need frequently to change filter paper during use.
But just, due to the limitation of glass fibre in itself, cause the resistance to elevated temperatures of glass fiber filter paper from the point of view of current research
Not strong, current means can only be improved on the original basis, and not having to filter paper significantly improves, in addition by glass
The cleaning of filter paper is also inconvenient made from glass fiber, so the filter paper of research high temperature resistant and easy cleaning will turn near
The emphasis of year development.
The content of the invention
It it is 1~2 μm by fibre diameter the invention provides a kind of high temperature resistance and high strength automatically cleaning filter paper to overcome above mentioned problem
Basalt fibre, fibre diameter are that 2~4 μm of ceramic fibres, fibre diameter are that 2~5 μm of Zirconium oxide fibres, fibre diameter are 2~5 μm
Alumina fibre and high-temperature Resistance Adhesives composition, and impregnate one layer of nano-titanium dioxide film in filter paper fiber surface.The Black Warrior
Rock fiber and ceramic fibre are as a kind of inorfil, and not only stability is good, but also with electrical insulating property, anticorrosive, fire-resistant
A variety of excellent properties such as burning, high temperature resistant, strainability is good, and shear strength is high, uses it as filter paper raw material and is greatly lifted
The intensity and high-temperature stability of filter paper, and the different Zirconium oxide fibre of the length added and alumina fibre equally have height
Intensity, resistant to elevated temperatures characteristic, and the fiber of different length can mutually tangle mutual filling so that filter paper adhesion is improved, and is adopted
Multicomponent greatly reduces gas-flow resistance, improves filter efficiency.In addition it is thin in the nano titanium oxide of its surface dipping
Film causes filter paper to be provided with self-cleaning function so that its surface can keep self-cleaning effect for a long time, while titanium dioxide is also
Can by the harmful organic substances such as formaldehyde it is degradable be water and titanium dioxide, and do not cause secondary pollution, therefore not only environmental protection raising again
