Description

一种实现玻璃纤维芯材自分层的方法 A method fiberglass core to achieve self-stratifying

技术领域 FIELD

[0001]本发明涉及一种芯材自分层的方法,特别是涉及一种实现玻璃纤维芯材自分层的方法。 [0001] The present invention relates to a method for self-stratifying the core, particularly to a glass fiber core to achieve self-stratifying method. 技术背景 technical background

[0002]近年来,节能环保成为人们最关心的问题,传统的有机保温材料易燃易腐蚀的缺陷限制了其在建筑领域的广泛应用,而无机保温材料又存在保温性能差,密度大等缺点,有很大的局限性。 [0002] In recent years, energy saving people are most concerned problem, conventional organic insulation material flammable and corrosive defects limit its wide application in the construction field, and the presence of an inorganic insulation material and poor thermal insulation performance, disadvantages such as high density , it has great limitations. 因此人们越来越重视隔热保温材料的制作与使用,特别是对一些新兴、环保夹层材料的保温性能、隔音性能的研宄越来越深入。 Therefore, there is a growing emphasis on the creation and use of thermal insulation materials, especially for the study based on a number of new, environmentally friendly insulation properties of sandwich material, noise performance of more and more deeply.

[0003]真空绝热板是新型保温材料的一种,其基于真空绝热原理,通过最大限度的提高板内真空度并填充多孔低热导率材料而实现高效绝热,从其结构来讲,是由隔热性能良好的填充芯材和阻隔薄膜复合而成,复合时,先将阻隔薄膜作为保护表层包覆多孔的填充芯材,再通过减压抽真空使得保护表层和填充芯材紧密贴合,最后对保护表层薄膜进行热封封口。 [0003] The vacuum insulation panel is a new type of insulation material, which is based on the principle of vacuum heat insulator, through the inner plate to maximize the degree of vacuum and filled with a porous material of low thermal conductivity to achieve efficient insulation, in terms of its structure, is separated good thermal properties and filling a core material made of a barrier film composite, when the composite, the first barrier film as a protective surface layer coated core is filled porous, then evacuated under reduced pressure so that the protective skin and the core material is filled into close contact, and finally surface protection films of seal. 真空绝热板具有体积小、重量轻、导热系数低等优点,目前,国内的真空绝热板一般使用玻璃纤维作为内部的填充材料,即真空绝热板芯材,但是在现阶段芯材的制备过程中,离心玻璃棉毡主要是以单层玻璃纤维为主。 The vacuum insulation panel having a small size, light weight, and low thermal conductivity, current, domestic vacuum insulation panel is generally used as a filler material inside the glass fiber, i.e., the vacuum insulation panel core, but at this stage in the manufacturing process of the core , mainly centrifugal glass wool felt is glass fiber-based monolayer. 离心喷吹法制棉时,玻璃液通过导料管将连续的玻璃流股引入高速旋转的带小孔的离心器内,经离心力作用与燃烧火焰牵伸成玻璃棉。 When SYSTEM cotton centrifugal blast, the molten glass through the guide tube of the continuous stream introduced into glass spinner rotating at high speed with a small hole, into wool by centrifugal force drawing the combustion flame. 玻璃棉在下降过程中形成无序交错穿插状玻璃纤维,下落路径曲折,最终在集棉机上形成孔隙率高达70 %〜8〇%的单层玻璃纤维层,在使用的过程中其保温隔热性能与吸音性能都会受到一定程度的影响。 Wool formed during the descent disorder shaped glass fibers interspersed staggered, zigzag drop path ultimately form a single layer of the glass fibers up to 70% porosity in the set ~8〇% cotton, its use in the process of insulation performance and acoustic performance will be affected to some extent.

[0004]申请号为201010102777.0的发明专利公开了一种真空绝热板芯材制作方法,该发明针对现有技术真空绝热板芯材存在的成本高的问题,提供了一种真空绝热板芯材制作方法,包括如将岩棉纤维打浆上网、整形滚压、真空除湿和冷却成材等步骤,本发明优点是采用岩棉纤维,生产出的真空绝热板芯材,可以满足真空绝热板芯材所有需要具备的性能,另外其生产工艺简单,成本较低。 [0004] Application No. 201010102777.0 of the invention discloses a vacuum insulation panel core manufacturing method, the invention is directed to a high cost problems of the prior art vacuum insulation panel core, there is provided a vacuum insulation panel core materials produced by the method, as will be stone wool fibers comprising beating the Internet, shaping roll, the vacuum timber, etc. dehumidifying and cooling step, the advantages of the present invention is the use of rock wool fibers, to produce a core material of vacuum insulation panel, the vacuum insulation panel can meet all the needs of the core It has performance, while its production process is simple, low cost. 其缺点是生产的岩棉纤维芯材为一个整块,不利于后期的价格制作,另外对芯材的阻燃以及吸音性能有一定的影响。 The disadvantage is that the production of rock wool fiber core as a single piece, the price is not conducive to post-production, and the other has some influence on the flame retardant and sound-absorbing properties of the core material.

[0005]申请号为201210259:340.7的发明专利公开了一种离心玻璃棉在线强制分层装置, 该装置固定于集棉机多孔链板输送带上,位于相邻离心头中间,离心喷吹制棉时,沿输送带运动方向内侧离心头所形成的玻璃纤维棉被分层控制板压制成底层玻璃纤维棉,而外侧离心头所形成的玻璃棉则被压制到底层纤维上,形成分层的离心玻璃棉毡毛坯,厚度分层控制板上还设有气道,通过上下檐两侧的进气孔和出气孔,可对飘落无重心的玻璃棉一定方向、一定大小的风力,提高了离心玻璃棉的使用率。 [0005] Application No. 201210259: 340.7 patented invention discloses a centrifugal force layered glass wool line means fixed to the cotton perforated collector conveyor chain plate, away from the adjacent intermediate heart, centrifugal blast system when cotton, the direction of movement along the inside of the belt from the glass fiber blanket heart layered board formed by pressing into a base glass wool fibers, glass wool and the heart from the outside of the formed fibers were pressed onto the bottom layer, forming a stratified centrifugal glass wool felt rough, the thickness of the control panel also has a layered airway through the intake hole and the upper and lower sides of the eave vents, may be no center of gravity of the falling glass wool in a certain direction, a certain wind speed, improved centrifugal usage of glass wool. 本装置的优点是可实现玻璃棉的在线自动分层,改善了人工分层所得玻璃棉毡绝热、吸音性能不够优异的问题,得到分层的离心玻璃纤维棉毯。 Advantage of the device is achievable wool line automatic delamination, improved delamination problems resulting artificial wool felt insulation, excellent sound absorbing performance is not enough to obtain a glass fiber blanket layered centrifugation. 其缺点是该方法不能实现〇.3mm芯材的量产,具有一定的局限性。 The disadvantage is that this method can not be achieved 〇.3mm core production, has certain limitations.

[0006]如上述两个专利,现有的玻璃纤维芯材的厚度具有一定的局限性,部分是整体成型后进行加工,另一部分的厚度在1. 〇mm左右,还不能实现0.3mm芯材的量产,因此需要一种新型的芯材自分层的方法来解决现有的问题。 [0006] The above two patents, the thickness of the conventional glass fiber core material has certain limitations, post-processing portion is integrally formed, the thickness of the other portion of 〇mm about 1, the core material can not be achieved 0.3mm mass production, and therefore a need for a novel method for self-stratifying core to solve the conventional problems.
