Description
Technical field
The present invention relates to inorganic material surface technical field of modification more particularly to a kind of basalt chopped fiber to produce work
Skill.
Background technology
Continuous basalt fiber is that melting is formed in 1500 DEG C or so of high temperature using natural basalt ore as raw material
State is molded by platinum-rhodium alloy bushing, then the continuously fiber of tens thousand of rice made of wire drawing machine high speed pulling.It is a kind of
Novel environment friendly inorganic fibers have lightweight, high-strength, high temperature resistant, corrosion-resistant, anti-oxidant, radiation protection, thermal acoustic insulation etc. excellent
Performance is the novel high-performance fiber after carbon fiber, aramid fiber, superhigh molecular weight polyethylene fibers, space flight and aviation,
The fields such as automobile ship, civil engineering traffic, energy environment, chemical industry fire-fighting, defence and military have extensive use.Especially handed in building
Logical field can effectively improve these three basis materials since itself and cement, concrete, pitch all have good compatibility
Intensity and cracking resistance, thus the chopped yarn of basalt fibre is widely used as additive and is added among these base materials.
Compared to other matrix reinforcing materials, such as common glass, PET fiber, lignin fibre, basalt chopped fiber
Although performance is better than other same type of material, its production cost is also relatively high, largely limits manufacturing enterprise
The application range of development and basalt fibre, and main cause is that its traditional processing technology and its own characteristics match degree are lower
Reason.
In traditional processing technology, basalt ore can obtain a number after high-temperature fusion, wire drawing, receipts silk
The continuous fiber of myriametre length, being then passed through heat treatment makes the size curing molding of fiber surface and removes extra moisture, so
Afterwards by chopping machine by fiber from wire drawing tube unwrapping and be chopped to setting length, finally by screening, packaging i.e. obtain it is profound
The chopped yarn finished product of military rock fiber.There is certain thickness since the long continuous fiber of tens thousand of rice is looped around on wire drawing tube, thickness is reachable
50~60mm, and basalt fibre itself has excellent heat-proof quality, and heat treatment time is caused to usually require 12h or more ability
So that temperature is transmitted to the inner fiber on wire drawing tube and makes the complete dehydrating and curing of the infiltration on its surface；However, outer on wire drawing tube
The size of layer fiber surface has just been fully cured within 3h, and beginning is gradually old in high temperature in subsequent 9h
Change, performance declines；Traditional processing technology not only causes a large amount of waste of energy, increases production cost, also results in each receipts
There is larger difference in the performance between outer layer fiber and inner fiber on silk cylinder, only for tensile strength, between the two
Fluctuating range ((randomly selects 30 bursts of chopped strand tests, it is wave that the difference of maxima and minima, which accounts for the percentage of minimum value,
Dynamic amplitude)) it causes greatly to fluctuate up to 40%, thus to batch properties of product.
Further, since chopping machine rotating speed is very fast, fibre diameter is minimum, quality is extremely light and dry tack free, during chopped
Easily generate largely winged silks, operating personnel must whole body wearing protective articles avoid a large amount of micron-sized winged silks be attached to clothing and
With, cause itch to be pricked with needle and feels；Chopped workshop must be also chambers are individually isolated, and high-power drain facility, workshop are installed in workshop
Outer installation pond, by the winged silk being discharged from workshop collect get up avoid pollution environment, these all to production add trouble at
This.
Invention content
The present invention overcomes the deficiencies in the prior art, overcome the deficiencies of existing technologies, and provide life that is economic, practical and stablizing
Power consumption is not only greatly decreased in production. art, the production technology, improves production environment, reduces production cost, and can ensure
The homogeneity of properties of product is greatly improved while product quality.
In order to solve the above-mentioned technical problem, technical scheme is as follows：
A kind of basalt chopped fiber production technology,
1.1) continuous fiber step：Fibrous raw material is melted by smelting furnace, and furnace body is flowed out by bushing, then is led by wire drawing machine
Under drawing, size is completely covered by baster, then passes through gathering roll plying, strand oscillator winding displacement, to draw winding again
On wire drawing tube, continuous fiber is obtained；
1.2) lubricant application step that is chopped is configured：Lubricant be chopped by 0.1~0.5wt% polyvinyl alcohol, 0.02~0.1wt%
Fatty acid distribution of coconut oil diglycollic amide, 0.02~0.1wt% acetylenic glycols composition, remaining is deionized water, mixing speed 60r/min
To 120r/min；
1.3) be chopped step：Wire drawing tube is removed from receipts roll dies, is sprayed continuous fiber unwrapping and by spray equipment
Upper chopped lubricant, then be chopped by chopping machine, obtain chopped strand；
1.4) packaging step is screened：Chopped strand is shifted and is tiled onto sieve, sieve is put into baking oven heat treatment；Again
Sieve is taken out from baking oven, and category filter is carried out according to different length to chopped strand, is packed after being re-weighed.
Further, chopped lubricant includes 0.3g wt% polyvinyl alcohol, 0.05wt% fatty acid distribution of coconut oil diethanol acyls
Amine, 0.05wt% acetylenic glycols, remaining is deionized water.
Further, size is by mass percentage, composed of the following components：Film forming agent 0.5~25%, coupling agent 0.1
~1.5%, lubricant 0.01~1.5%, antistatic agent 0.1~1.5%, fibre single thread dispersant 0.1~5%, other is to go
Ionized water.
Further, fibre single thread dispersant includes inositol hexaphosphate, Cocoamidopropyl betaine, acetylenic glycols, boron
Its ratio of acid alkylolamide ester is followed successively by 1:3.5:3:2.5.
Further, it is 20~60ml/min that spray equipment, which uses humidifier, spraying rate,.
Further, chopped strand length is 1~60mm.
Further, baking oven heat treatment temperature is no more than 220 DEG C, and heat treatment time is in 2h to 4h.
Advantage is the present invention compared with prior art：The present invention is short by the long continuous fiber of tens thousand of rice being wrapped on wire drawing tube
It is cut into after short several millimeters of length, so that the fiber for being covered by internal layer is exposed, dramatically increase continuous fiber
Aerial exposed area, and chopped strand is rendered as the distribution that 3 D stereo mutually supports, and exists between fiber big
Gap is measured, the aerial exposed area of fiber is further increased.It is heat-treated in such a state, heat is easy to
All chopped strand surfaces are transmitted to, the curing rate of each position fiber surface size is not only substantially accelerated, will be chopped
The heat treatment of fiber process time foreshortens to from 12h or more within 4h, substantially shortens the production cycle, saves a large amount of electric energy losses and (dries
Case power is generally 50KW, and for quantity generally at 4~10, every baking oven every year can 100,000 yuan or so of power cost saving) it is greatly reduced
Production cost；Moreover, all chopped strands almost start to be heated at the same time, surface to be heated evenly degree very high, into
And making the performance inconsistency of every batch of product substantially smaller, the fluctuating range of single-stranded fiber tensile strength (randomly selects 30 strands to be chopped
Fiber is tested, and it is fluctuating range that the difference of maxima and minima, which accounts for the percentage of minimum value) it is reduced to from original 40%
Within 5%.
In addition, giving one layer of chopped lubricant of its surface spraying before fiber enters chopping machine, it can effectively ensure fibre
The convergence of dimension reduces the frictional force between fiber and chopping machine so that single-stranded fiber will not be from one during quick be chopped
Stock is dispersed into the tens of or even hundreds of parts of minimum fibre single threads of quality, winged silk is in the presence of to be avoided on source.Behaviour
Make personnel and be not necessarily to whole body protection, and only with dressing usual work clothes operation, since there is no a large amount of discharges for flying silks and
Collection problem keeps production more convenient, and cost is lower.
It should be noted that the size coated during production continuous fiber cannot substitute chopped lubricant.Reason has
Two：(1) lubricant that is chopped has better room temperature boundling and filming performance, further can preferably improve the boundling of fiber
Property, it is ensured that single-stranded fiber is not disperseed during chopped, and the effect of size mainly makes finished product chopped strand have more preferably
Application effect；(2) in actual production, the continuous fiber of new production will not generally carry out subsequent machining operations immediately, but
The time of can class first be stored even a couple of days waits running up to certain amount and carry out post-processing in batches again, receives silk during this period
The size on continuous fiber surface will not cure substantially on cylinder, and convergence is poor, simultaneously because volatilization can largely naturally
Dehydration is just easier be in the presence of filoselle, winged silk when chopped if being not coated by chopped lubricant before being chopped.Due to
The solid content of chopped lubricant is relatively low, and quantity for spray is smaller, thus the performance influence very little to having applied size.
Generally speaking, using the present invention chopped strand production technology, improve to the full extent production technology with it is profound
Matching degree between military rock fiber self-characteristic, fiber size characteristic, reduces production cost, improves product from many aspects
Average behavior and stability, optimize production technology, improve production environment.

Than comparative example, all there is apparent superiority in all fields.The length of common chopped strand is in 6~35mm, thus the length field
Between other than no longer citing repeat.
Embodiment 2 is since chopped lubricant concentration used is less than technical solution of the present invention, and there are about 60% ratios after being chopped
There is filoselle, and filoselle can lead to that between fibre single thread stress can not be synchronized so that tensile strength integrally reduces, due to the fibre that is chopped
Dimension is not dried first, and is coated with chopped lubricant, therefore water content is higher, and winged silk on a small quantity is only will produce when being chopped.
Embodiment 3 is higher than technical solution of the present invention due to chopped lubricant concentration used so that adheres on fiber is short
Cut that lubricant is excessive, the performance to having size on fiber produces excessive influence so that tensile strength integrally reduces, but

There is certain rigidity after agent solidification, during chopped, 10% ratio is had under quick and larger shearing force and is gone out
Existing filoselle；Since chopped strand has been heat-treated, surface is extremely dry, and 10% filoselle almost all is caused to be chopped machine production
Raw air-flow dispels in air, and then generates seriously winged silk.
Since Examples 1 to 6 is all made of technical solution of the present invention technological process, it is heat-treated again after being chopped, by
Hot uniformity coefficient is very high, thus chopped strand tensile strength fluctuating range (randomly select the test of 30 strands of chopped strands, maximum value with
The percentage that the difference of minimum value accounts for minimum value is fluctuating range) within 5%, it is much smaller than comparative example.Therefore this programme
The defect for overcoming the prior art completely, provides production technology that is economic, practical and stablizing, which is not only greatly decreased
Power consumption improves production environment, and properties of product are greatly improved while reducing production cost, and can ensure product quality
Homogeneity.
