Abstract
A kind of fiberglass needled mat disclosed in the utility model, the multilayer feltwork become by fiber combing, laying is formed, the vertical staple fiber that the acupuncture that alternates between described multilayer feltwork is formed, described vertical staple fiber and each layer fiber of feltwork interconnect, it is characterized in that, fiber in described multilayer feltwork is short glass fiber, and the fiber in described multilayer feltwork is filament, has three-dimensional micropore structure; Described short glass fiber includes countless fixing air pocket.The beneficial effects of the utility model are: disconnected hot good, can not burn, acoustic absorptivity is good, and insulating properties is high, and corrosion resistance is high, and restoration is good, and hydroscopicity is low, lightweight and soft.
Description
Technical field
The utility model relates to bondedfibre fabric technical field, particularly relates to a kind of fiberglass needled mat.
Background technology
Along with the enhancing of people's environmental consciousness, the range of application of Nomex constantly expands.Wherein, Nomex is used for sound insulation in auto industry, sound-absorbing, damping, fire-retardant etc., also can be used for the filtration art in industry, such as filtering high-temperature flue gas.In the automotive industry for sound insulation, sound-absorbing, damping, fire-retardant have simple glass cotton, the institutional framework of simple glass cotton is poor, and fiber footpath is little, larger to harm.
Utility model content
Technical problem to be solved in the utility model: a kind of high temperature resistant, stable chemical performance, fiberglass needled mat that sound-absorbing antiseptic property is good are provided for existing needs and the deficiencies in the prior art.
The technical problem that the utility model solves can realize by the following technical solutions:
A kind of fiberglass needled mat, the multilayer feltwork become by fiber combing, laying is formed, the vertical staple fiber that the acupuncture that alternates between described multilayer feltwork is formed, described vertical staple fiber and each layer fiber of feltwork interconnect, fiber in described multilayer feltwork is short glass fiber, fiber in described multilayer feltwork is filament, has three-dimensional micropore structure; Described short glass fiber includes countless fixing air pocket.
Owing to have employed technical scheme as above, the beneficial effects of the utility model are:
1, disconnected hot good: according to physical principle, all there is a lot of air pocket the heat insulation material matter inside that the pyroconductivity of gas is little, outstanding.And the utility model has countless three-dimensional micropore, and fiber presents irregular alignment, and be splendid heat-barrier material, the coefficient of heat conduction is between 0.2 ~ 0.040kcal/mhr.c;
2, can not burn: the main component of glass fibre is silica (accounting for more than 52%), there is noninflammability, without distortion, without brittle, high temperature resistantly reach 700 DEG C;
3, acoustic absorptivity is good: when sound wave invades glass fibre, sound energy because of the friction with fiber and the air pocket that varies in size, and can be sucked in a large number.Generally speaking, acoustic absorptivity, all up to more than 90%, can effectively prevent noise from disturbing;
4, insulating properties is high: use glass fibre energy high temperature resistant, mechanicalness is good, and chemical stability is high, has good insulating properties;
5, corrosion resistance is high: glass fibre is not afraid of strong acid, highly basic, can not lower its functional characteristic for a long time;
6, restoration is good: glass fibre includes countless fixing air pocket, and restoration is fabulous.Be not afraid of any impact endurance test shock, equal more than the 1.0kg of tensile strength.
7, hydroscopicity is low: glass fibre hydroscopicity is usually close to zero.
8, lightweight and soft: to compare with other heat insulation materials, the lighter weight of fiberglass needled mat, more soft, if be arranged on mechanically, the load of its weight and vibrations can be alleviated.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
A kind of fiberglass needled mat 100 of the present utility model, as shown in Figure 1, the short silk of glass fibre is cut into by short for filament of glass fiber, use corresponding special equipment shredding, combing, lapping again, by very thin feltwork laying from level to level, in layer structure, the corresponding number of plies is superposed according to reaching desired thickness, then by needing machine, positive and negative acupuncture is carried out to feltwork, wherein the weight of every layer utilizes electronic platform scale to claim to control every square of weight, to reach the standard weights preset, obtained the utility model as shown in Figure 1.The multilayer feltwork 110 become by glass fibre combing, laying is formed, the vertical staple fiber 120 that the acupuncture that alternates between each layer is formed, vertical staple fiber 120 with
multilayerfeltwork 110 each layers of fiber interconnect, and the fiber in multilayer feltwork 110 is short glass fiber, and the fiber in multilayer feltwork 110 is filament, has three-dimensional micropore structure; And described short glass fiber includes countless fixing air pocket.
The main component of glass fibre is silica, and the content of silica reaches more than 52%, has noninflammability, without distortion, without brittle, high temperature resistantly reaches 700 DEG C.The utility model has countless three-dimensional micropore, and fiber presents irregular alignment, and be splendid heat-barrier material, the coefficient of heat conduction is between 0.2 ~ 0.040kcal/mhr.c.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
