Abstract
The invention relates to foam glass, in particular to fiber reinforcement foam glass. The fiber reinforcement foam glass comprises foam glass and is characterized in that reinforced fiber is arrangedin the foam glass; the reinforced fiber relates to any one or the combination of more than any two of glass fiber, carbon fiber and metal fiber. The diameter of the reinforced fiber is 4.0-25mum; andthe length of the reinforced fiber is 0.20-10.0cm. The invention has the advantages that the foam glass can effectively reinforce the strength of the foam glass, reduces the abrasion thereof in the processing, transformation and use process; and the fiber and the foam glass body can be firmly and effectively banded together and are not easily cracked in the annealing process.
Description
Technical field
The present invention relates to a kind of multicellular glass, be specifically related to a kind of fibre-reinforced multicellular glass of using.
Background technology
Multicellular glass is to utilize glass cullet to be main raw material, adds whipping agent, properties-correcting agent, foamed promoter etc. in levigated glass powder, through be placed on behind the uniform mixing specific framed in.In tunnel like calcining kiln or other foaming furnace, be heated to 700～900 ℃, make it softening the expansion and form the porous glass material that a kind of inside is full of countless even bubbles.From framed, take out then, send into Xu Lengzhi normal temperature in the annealing furnace, cut saw at last and be processed into certain size.
Multicellular glass has that density is little, thermal conductivity is little, fire prevention, corrosion-resistant, wide, airtight, nonhygroscopic, the easy processing of use temperature scope, be not subjected to advantages such as rat eaten.Multicellular glass is of many uses, not only is used for petrochemical industry, fermented soy industry, construction industry etc. as lagging material, and as cold insulation material, is used on food refrigerated, cold storage warehouse and the cabin.The particularly further raising that requires along with China's building energy conservation subordinate phase 50% and the exterior-wall heat insulation of phase III 65%, building energy-saving renovation is mentioned schedule, and multicellular glass more and more is used to the lagging material of exterior wall and roofing.
But because multicellular glass is a kind of low density material, its physical strength is lower, and is easily crisp, opposing external shock poor-performing.At present prepared multicellular glass breadth is mostly smaller, also needs fixedly to prevent its fracture with the reinforcing bar tie rod in construction process, has caused like this that service routine is numerous and diverse, construction quality and the difficult assurance of effect.
(name is called Chinese patent publication number CN200946127: the intensity that wired multicellular glass) strengthens multicellular glass in the middle of multicellular glass by the mode that wire cloth is set.At first on the multicellular glass admixtion, place the latticed wire cloth of one deck, the multicellular glass admixtion of identical weight below wire cloth upper berth one deck and silk screen more at last prepares the higher wired multicellular glass of intensity according to known multicellular glass manufacturing process afterwards.But because the difference of the coefficient of expansion between metal and the glass material easily produces cracking and damaged in annealing and use.
Summary of the invention
The object of the present invention is to provide a kind of fiber reinforced foam glass, this multicellular glass has physical strength height, construction effect is good, safety in utilization is good characteristics.
For achieving the above object, the technical solution used in the present invention is: a kind of fiber reinforced foam glass, it comprises multicellular glass, it is characterized in that being provided with in the multicellular glass fortifying fibre.
Described fortifying fibre refers to any one or any mixing that (contains any two kinds) more than two kinds in glass fibre, carbon fiber, the steel fiber (as aluminum fiber), and any is any proportioning when mixing more than two kinds.
The diameter of described fortifying fibre is 4.0～25 μ m, and the length of fortifying fibre is 0.20～10.0cm.
Adopt known multicellular glass production technique, in admixtion, add the fortifying fibre (addition of fortifying fibre be multicellular glass batch weight 3.0%～15.0%) of 3.0wt%～15.0wt% during batching.
The invention has the beneficial effects as follows (comparing): by in the multicellular glass admixtion, introducing fortifying fibre with existing multicellular glass, can effectively increase the physical strength of multicellular glass, avoid its breakage in processing, transportation and use, construction effect is good, safety in utilization is good; Can increase the breadth of foam glass board when making sheet material, its operating efficiency is improved.
Embodiment
In order to understand the present invention better, further illustrate content of the present invention below in conjunction with example, but the present invention not only is confined to the following examples.
Embodiment 1:
