Detailed description of the invention
Fig. 1 is the linear graph that body paper moisture percentage of the invention influences the absorbability of 25% acrylic latex.
Specific embodiment
With specific embodiment, the invention will be further described with reference to the accompanying drawing：
The manufacturing method of air purification filter skeletal support material, includes the following steps：
(1) PET fiber of at least two specifications is proportionally added into the stock tank of beater and discongest mashing processing,
Composite fibre is made, composite fibre slurry concentration controls between 3-5%, and adjusts ph value to 9, and is heated to 120 DEG C of stirrings 5
Minute, later plus cold water is diluted between concentration 0.5-0.7%, and is down to room temperature and is adjusted PH to 6, and dispersing agent and wet is added
Strong agent continues stirring 10 minutes, PET fiber specification requirement be rugosity between 1.5-25dtex, length is between 12-25mm；
(2), composite fibre is manufactured paper with pulp into body paper through oblique net paper machine；
(3), it is dehydrated：By body paper by vacuum suction dehydration, make moisture percentage between 50-55%；
(4), coating fluid selects the acrylic latex or styrene-acrylic latex of 20%-30% concentration, addition in coating fluid per hundred parts
1 part of Nanometer Copper, 2 parts of nano-calcium carbonate calcium powder, 2 parts of nano active powdered carbon and 3 parts of aqueous compound emulsifying agent, stir evenly mixing, into
Row modification；
(5), it is glued：Coating fluid is sprayed at dewatered body paper surface；
(6), dry：It first passes through infrared drier and carries out pre-dried, drying temperature is 200 DEG C；Using hot air drying
Dry machine is dried, and drying temperature is 180 DEG C；It is finally dried by baking oven, oven temperature is 210 DEG C；Using this drying side
Method, reaching required standard moisture content only needed in 60-70 seconds, and rate of drying greatly improves；
(7), it is wound into finished product.
In step (1), this product selects PET fiber, and fold processability is good, low in cost, the composite fibre of different size
Slurry carries out basic treatment by heating in advance and lye being added, and can improve the smoothness of fiber surface, improves soil resistance, and
It enables to after causing body paper, air permeability improves；Acid solution is added later to neutralize, and makes its slant acidity, is convenient for after forming and coating
Liquid can be preferably compound；Dispersing agent can be such that PET fiber is preferably dispersed in water, soluble easily in water；Wet strength agent can increase
Wet strength.
In step (2), body paper is manufactured paper with pulp by inclined wire wet process, and fiber interweaving is good, and Air permenbility is high, and vapour lock is small, stiff degree
It is high.
In step (3), it is dehydrated by the way of vacuum dehydration, vacuum degree control makes it in 0.12MPa-0.13MPa
Moisture percentage between 50-55%, show by test of many times as shown in Figure 1, when moisture percentage be higher than 55% when, body paper absorbability
Small, coating fluid is not easy to be absorbed, application difficulties；When moisture percentage is lower than 50%, when spraying, body paper absorbability increase increased
Fastly, it being easy transfer accumulation after coating fluid spraying, uniformity is bad, lead to air permeability and the stiffness decline of backing material, so its
Make moisture percentage between 50-55% when, Painting effect is best, and be coated with after air permeability and stiffness be preferably also.
In step (4), acrylic latex or styrene-acrylic latex can increase the intensity and stiffness of backing material, and to support
The resistance performance Index Influence of material is also small, wherein select 20%-30% concentration when, effect is best, by addition Nanometer Copper and
The wearability of backing material can be improved in the addition of nano-calcium carbonate calcium powder, improves material by the addition of nano active powdered carbon
Antibiotic property can make Nanometer Copper, nano-calcium carbonate calcium powder and nano active powdered carbon more equal by the addition of aqueous compound emulsifying agent
Even is dispersed in acrylic latex or styrene-acrylic latex, improves final using effect.
In step (6), before drying, body paper also has more water content, directlys adopt baking oven according to traditional
The mode of drying, drying time is long, and moisture is not easy outlet, although final water content is extremely low, can surpass and body paper hole is caused to receive
Contracting, air permeability and stiffness decline, this technology carry out pre-dried by infrared drier, and thermal break-through ability is strong, can be to material
Inside carries out convection drying, and by air drier, carries out quick outlet to the steam generated after material heating, finally by
Baking oven carries out freeze-day with constant temperature, short the time required to dry, can reach standard needed for moisture content, backing material will not generate change
Shape, it is ensured that the requirement of air permeability and stiffness.
Wherein PET fiber body paper made from different size accounts for the mass percent in air filting material skeletal support material
For 65%-75%, coating fluid accounts for the mass percent in air filting material skeletal support material for 25%-35%, in use
State proportion, the spraying effect of PET fiber body paper and coating fluid is best, and backing material stiffness obtained is high, air permeability is high.
Specific embodiment 1-8 is made by above-mentioned manufacturing method according to the different ratio system of different ratio different size fiber,
As shown in table 1.
Table 1：
Experimental test is carried out by backing material made from embodiment 1-8, such as the following table 2 is made：
Table 2：
In conjunction with table 1-2 it is recognized that while can be reached when using two kinds, three kinds, four kinds or the fiber with more kinds of specifications
To control standard, but when using three kinds of gauge fiber proportions, attainable air permeability and stiffness are best, and embodiment 4-6 is equal
For optimum embodiment, and in embodiment 4 fiber by 30%7dtex*12mmPET fiber+60%25dtex*25mmPET fiber+
When the ratio investment of 10%1.5dtex*12mmPET, effect is best.
Continue test obtain when selecting above-mentioned three kinds of specifications, with 25dtex*25mmPET fiber content by 30% to
60% is gradually increased, and stiffness and air permeability will be slow raising, but when 25dtex*25mmPET fiber content is higher than 60%,
Stiffness and air permeability can accelerate to decline, therefore when PET fiber specification is three kinds of 7dtex*12mm fibers including 30-60% content
A, the 1.5dtex*12mm fiber C of 25dtex*25mm fiber B and the 10-20% content of 20-60% content, and fiber A, fiber B
Total amount with the sum of fiber C three is 100%, and backing material comprehensive performance obtained is best.
In addition, in embodiment 4-6, but the rugosity of fiber A can float between 6-8dtex, and the rugosity of fiber B can be with
It floats between 23-25dtex, the rugosity of fiber C can float between 1.5-3dtex, and backing material obtained is comprehensive
It can be closer to.
Above-described embodiment is only presently preferred embodiments of the present invention, is not limited the scope of the invention according to this, therefore：It is all according to
The equivalence changes that structure of the invention, shape, principle are done, should all be covered by within protection scope of the present invention.
