Dolomite etc. is primary raw material, is prepared through techniques such as high-temperature fusion, centrifugal drying silk, slagging-off, chopped, classification, the modified, dryings in surface
It forms.About 1200 DEG C of the fusing point of man-made mineral fiber, fiber surface is smoothly complete, safe to use not will cause human body wound
Evil.
With the implementation of friction material industry disabling asbestos policy, man-made mineral fiber becomes the main substitution of asbestos fibre
Fibrous material has the distinguishing features such as braking steady reliable, high-temperature behavior is good, abrasion are small, low noise, service life length, deep to be rubbed
Wipe liking for material producer.In construction material, mineral fibres is also because the performances such as its excellent heat-insulated, heat preservation are widely answered
With.
In recent years, with the increase of man-made mineral fiber's application amount and range, fiber is easy to reunite, bad dispersibility, with base
The defects of body interface associativity is bad highlights further, becomes man-made mineral fiber's production, the critical issue urgently to be solved in.
Summary of the invention
The purpose of the present invention is to propose to a kind of preparation method of modified artificial mineral fibres, the fiber products of this method preparation
Quality is stable, process is simple, using not easy to reunite, effect is good in conjunction with basal body interface.
The present invention is achieved through the following technical solutions: a kind of preparation method of modified artificial mineral fibres, including as follows
Step:
(1) fiber is chopped, is classified: fibrinogen carries out the processing that is chopped through chopping machine, and the spinner velocity that is chopped is 2400~3000r/
Min, the length of fiber is 1~3mm after being chopped, and fiber be classified after being chopped, and classifying turbine revolving speed is 300~500 r/
min；
(2) modifying process of fiber: chopped, classification fiber being modified, is divided into two section surface spraying process and carries out, and the
Two sections of spraying points ratio at a distance from first segment spraying point is 5:3, and the quantity for spray of first segment spraying point is the 20% of chopped strand amount,
The quantity for spray of second segment spraying point is the 30% of chopped strand；
(3) dry: the entire modifying process of drying process perforating fiber, drying temperature are 80 DEG C~100 DEG C；
(4) it collects, pack: the fiber after drying being collected through filter cartridge dust remover, the modified artificial prepared can be obtained in packaging
Mineral fibres.
The step (1), (2), (3), (4) fiber are man-made mineral fibers using rock, ore as made of Raw material processing
Fibrous material.
In the above-mentioned technical solutions, the modifying agent can select film forming agent, antistatic agent, coupling agent to add water mixed preparing
It forms, modifier concentration is 0.5%~0.8%.
In the above-mentioned technical solutions, the film forming agent can select one or both of epoxy emulsion or polyester emulsion,
Additive amount is 5%~8%, and it is 0.03%~0.05% that antistatic agent, which selects ammonium salt class additive amount, and coupling agent selects KH550 or KH560
One or more of additive amount be 0.4%~0.6%.
The present invention has the advantages that compared with prior art
1, the addition of modifying agent is using two sections of progress, and second segment spraying point ratio at a distance from first segment spraying point is 5:3, in this way
Chopped strand is uniformly dispersed in entire modifying process, and modified effect is greatly improved.
2, the drying process of man-made mineral fiber runs through whole preparation process, both plays promotion to modifying process in this way and makees
With, and shorten the drying time of product.
3, the fiber product quality of this method preparation is stable, process is simple, using it is not easy to reunite, with basal body interface in conjunction with effect
Fruit is good.
