Border, melts the inner polystyrene expanded material of fiber solid sphere；Temperature is finally promoted to 150 DEG C, and carries out hot blast
Heating is blowed, glue is fully cured, it is 3-180KG/m to form vacuum-tight weight3Hollow fibre ball, preparation method letter
Just, production efficiency is high for folk prescription, and the product stability of preparation is good, have the advantages that lightweight, it is high-strength, do not absorb water.
Waterproof casing prepared by the inventive method meets the performance requirement such as the various depth of waters and intensity, lightweight low water absorption.
Specific embodiment
The technical program is explained in detail below in conjunction with specific embodiment.
Embodiment 1
The present invention is a kind of preparation method of waterproof casing, and it is to prepare hollow fibre ball first：With foamed polystyrene
The spheroid that material is made as carrier, first by feeding after spheroid impregnation be suspended with by glass fibre be made by vacuum static electricity
In the vacuum static electricity case of the ribbon of reason, high pressure is flown outstanding glass fibre and synthesize with spheroid under state of charge high, obtain fibre
Dimension solid sphere；Fiber solid sphere is sent into more than 120 DEG C of hot environment again, makes the inside polyphenyl second of fiber solid sphere
Alkene expanded material melts；Temperature is finally promoted to 150 DEG C, and carries out heat blow heating, glue is fully cured, form true
Empty closed hollow fibre ball.Its specific method step is as follows：
A, glass fibre is cut into length be 1mm, 2mm, 3mm, 4mm or 5mm ribbon, be re-fed into vacuum static electricity ring
Border, makes fiber entirely suspend and unidirectionally flies up by negative voltage；
Ball, using foamed polystyrene to the ball of required diameter, is put into glue by b, preparation as the spheroid of carrier
Groove, is carried out after impregnation to expanded material, carries out air-drying treatment, and glue mobility is greatly lowered；
C, by spheroid send into the quiet case of high pressure, fly outstanding fiber with high pressure and synthesize under state of charge high, obtain fiber solid
Spheroid；
D, fiber solid sphere is put into gum box it is completely soaked, surface is covered attachment fiber and fully infiltrated by glue；
After e, fiber solid sphere surface covering attachment fiber are fully infiltrated by glue, the warm high that more than 120 DEG C of feeding
Air channel is heated 15-20 minutes, melts medicine ball inside expanded material, and flowed out from fiber gap cavity；
F, temperature is promoted to 150 DEG C, carries out hot blast and blow heating, glue is fully cured, vacuum-tight sky is obtained
Core fiber ball.
Further, it is that first glass fiber material is put into water in step a, and adds dispersant, coupling agent immersion
Cut again afterwards.Ribbon adds couplant to be processed before vacuum static electricity case is sent into, first, is allowed to preliminary
Open effect；High pressure vacuum storehouse is sent to again, is dried by hot air circulation, material is dried and is fully opened.
Further, the glue in step b uses water base glue such as water-based epoxy resin.
On the basis of the above, glass microballoon and ring are added in the hollow fibre ball of above-mentioned required diameter being inserted into mould on demand
Oxygen tree fat is simultaneously heated, vibrates solidification, and solidification can form required waterproof casing in 2-6 hours；The said goods can also enter
Row is machined out, and such as drills.
Embodiment 2
In the present embodiment, the order of step a and step b is exchanged.First prepare as the spheroid of carrier, then again by glass
Fiber cuts into the ribbon that length is 1mm, 2mm, 3mm, 4mm or 5mm, is re-fed into vacuum static electricity case, and fibre is made by negative voltage
The whole suspension of dimension unidirectionally flies up, and is that ribbon could be formed with the arrangement of effect rule, to product most using unidirectional advantage
Whole strength character has a good guarantee.
The present invention compared with prior art, uses the spheroid being made using polystyrol foam material as carrier, first by ball
Feeding is suspended with the vacuum static electricity case of the ribbon being made up of glass fibre after body impregnation, high pressure is flown outstanding glass fibre and is existed
Synthesize with spheroid under state of charge high, obtain the fiber solid sphere that weight is 3-180KG/m3；Fiber solid sphere is sent again
Enter more than 120 DEG C of hot environment, melt the inner polystyrene expanded material of fiber solid sphere；Finally temperature is lifted
To 150 DEG C, and heat blow heating is carried out, glue is fully cured, form vacuum-tight hollow fibre ball, preparation method letter
Just, production efficiency is high for folk prescription, and the product stability of preparation is good, and performance is more superior.
Fiber of the invention can also use glass fibre, quartz fibre or carbon fiber or Kafra fiber, preferential to use
Carbon fiber or Kafra fiber.Couplant, dispersant in its technique, coupling agent are existing conventional buying product, are wanted without special
Ask, the present invention does not make carefully to state herein.
Above-described is only the preferred embodiment of the present invention, it is noted that for one of ordinary skill in the art
For, without departing from the concept of the premise of the invention, various modifications and improvements can be made, these belong to the present invention
Protection domain.
