Abstract
The invention discloses a composite glass fiber needed felt. The composite glass fiber needed felt is prepared from such components in percentage by weight as 10%-18% of tetrafluoroethylene paste resin, 6%-15% of polymethylphenyl siloxane fluid, 4%-11% of acrylic resin, 0.5%-1.5% of silane coupling agent, 0.1%-0.5% of sorbide, 0.5%-1.5% of ethanol, 0.3%-1.2% of lead acetate and the balance of water. The composite glass fiber needed felt is high in elasticity, impact resistance and wear resistance; the formed felt cloth is high in firmness, long in service life and complex in structure.
Description
Technical field
The present invention relates to a kind of glass fibre compound spiked felt.
Background technology
Fiberglass needled mat is a kind of filtering material of rational in infrastructure, better performances, taking glass fibre as raw material, carry out acupuncture with stinging for the chopped glass fiber felt after combing, with mechanical means make between carpet veneer glass, carpet veneer glass and strengthen fiber between glass base cloth and mutually tangle, fibre web is reinforced and the felted Nonwoven Filter Material made.
The glass fibre carpet veneer of prior art, general thickness is frivolous, is difficult for forming resin-rich layer, therefore elasticity, resistance to impact and the ABRASION RESISTANCE on surface are all poor, and between carpet veneer and base cloth to hook together firmness poor, service life is short, and structure is single, be difficult to adapt to the working condition of diversified environment.
Summary of the invention
The object of this invention is to provide a kind of glass fibre compound spiked felt, it can solve the above-mentioned shortcoming of prior art.
Technical scheme of the present invention is to provide a kind of glass fibre compound spiked felt, and each component and mass fraction thereof are:
As optimal technical scheme: each component and mass fraction thereof are:
The solid content that described tetrafluoroethylene is stuck with paste the tetrafluoroethylene in resin is 40%.
Advantage of the present invention is: elasticity, resistance to impact and ABRASION RESISTANCE are strong, and the felt-cloth firmness of formation is high, long service life and complex structure.
Detailed description of the invention
Further set forth the specific embodiment of the present invention below:
A kind of glass fibre compound spiked felt, each component and mass fraction thereof are:
Embodiment 1: a kind of glass fibre compound spiked felt, each component and mass fraction thereof are:
Embodiment 2:
Plant glass fibre compound spiked felt, each component and mass fraction thereof are:
Embodiment 3:
Plant glass fibre compound spiked felt, each component and mass fraction thereof are:
In embodiments of the invention, the solid content that described tetrafluoroethylene is stuck with paste the tetrafluoroethylene in resin is 40%.
It not only has advantages of that Woven glass cloth is high temperature resistant, corrosion-resistant, dimensionally stable, elongation shrinkage factor is minimum, intensity is high, and carpet veneer fiber is filament, three-dimensional micropore structure, porosity is high, little to gas filtration resistance, be a kind of higher speed, efficient high-temperature-resistant filtering material.Compared with other high temperature resistant chemical fibre felt, it has, and price is low, the more high special benefits of heatproof, but its running resistance is higher than general chemical fibre high temperature filter material.
Unordered staggered interting of the glass fiber single filament of glass fibre compound spiked felt, is omnidirectional three-dimensional micropore structure, and space is little, and space rule is large, has good sound-absorbing, damping, corrosion-resistant, insulation, high temperature resistant, fire-retardant performance.Porosity is high, and gas filtration resistance is little, and filtration velocity is large, and efficiency of dust collection is high, has resistance to bending simultaneously, and wear-resisting, dimensionally stable fiberglass needled mat is mainly as the enhancing base material of manufacturing thermoplastic sheet moulding compound AZDEL and crystalline p p sheet (GMT).In the past, main application fiberglass continuous needle-punched felt, but through contrast and selection repeatedly, think while using glass chopped Nomex, its processing characteristics and serviceability are better than using fiberglass continuous needle-punched felt, while being mainly reflected in glass chopped Nomex and polypropylene composite materials, mobility is better.
All there are a lot of air pockets little, the outstanding heat insulation material matter inside of pyroconductivity of gas.Glass fibre acupuncture cotton has countless tiny gas, and fiber presents irregular alignment, is splendid heat-barrier material, the coefficient of heat conduction 0.2～0.040kcal/mhr.Between c; The main component of glass fibre is silicide (accounting for more than 50%), have noninflammability, without distortion, without embrittlement, the high temperature resistant 7000C that reaches; Sound wave is invaded when glass fibre cotton, phase energy can because of with the friction of fiber and the air pocket that varies in size, and sucked in a large number.Generally speaking, acoustic absorptivity, all up to more than 90%, is the good ability that prevents that noise from disturbing; Glass fibre can be high temperature resistant, and mechanicalness is good, and chemical stability is high, is best insulating materials; Glass fibre is not afraid of strong acid, highly basic, can not lower for a long time its functional characteristic; Glass fibre includes countless fixing air pockets, and restoration is fabulous.Be not afraid of any impact endurance test shock, more than the equal 1.0kg of tensile strength.Hydroscopicity is conventionally close to zero.With other heat insulation material comparisons, the quality of fiberglass needled mat the gentliest, the most soft, if be arranged on mechanically, can alleviate the load of its weight and vibrations.
Glass fibre compound spiked felt of the present invention is prepared by the following method: glass fiber is prescinded to rear shredding, input to cotton machine, send into carding machine by cotton feeder by predetermined volumes or weight; Carding machine is carded to chopping root root monofilament formation mat net and transfers out on conveyer belt; Mat stratum reticulare layer laying reached predetermined thickness by lapping machine; Needing machine carries out acupuncture to feltwork, and fiber is connect mutually, becomes the fiberglass needled mat-determine with intensity; By the glass mat heat hot phase-splitting after acupuncture, then send into leaching in strong acid groove; Water cleans the glass mat after leaching, then by containing neutralization solution processing, dry; Dried glass mat is heated to 500～650 DEG C by heat-treatment furnace, the moisture on fabric and carbon are removed; Continue to be warming up to 800～1000 DEG C, sintering.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
