Abstract
The invention relates to a glass block with a plurality of pores, which is white and has uniformly distributed pores with a diameter of 0.5 to 2 millimeters. The pores are communicated with each other by regulating the adding amount of foam plastic particles. The raw material of the glass is powder produced by grinding waste glass fragments, and the foam plastic particles are added into the powder. Occupying bodies are decomposed by a heat treatment sintering process to form the pores, and the glass powder is sintered into a porous block. The pores increase the surface area of the glass, reduce the apparent density of the block, and improve the sound absorption and heat insulation capacity.
Description
Technical field:
The present invention relates to a kind of porous foam glass and preparation method thereof.
Background technology:
Along with country to the pay attention to day by day of building construction energy-conserving and environment-protective problem and the people rapid raising to the residential architecture specification of quality, the insulation that environmental protection, heat preservation energy-saving, particularly roofing and body of wall (face) are gone along with sb. to guard him in the house is the height of referred legislation progressively.The construction house is a fundamental task crucial for generations to come, and guarantee the reliability and the weather resistance of roofing and body of wall (face) insulation construction, just needs to use not only to have good environmental protection, heat-insulating property, but also will possess waterproof anti-freezing, and enough good lagging materials of durable weathering resistance are arranged.And this just ideal of multicellular glass integrates the New Building Materials of environmental protection, insulation, fire-retardant, damp proof insulation, sound-absorbing.This material internal is full of a large amount of pores, easily is cut into Any shape, has replaced brick and building block at present, as roofing, body of wall, ceiling material and heat insulating member (Liu Jun, Guo Zhimin. Chinese environmental colleges for training managerial personnel journal, 2005,15 (2): 59-60).
The external raw material of producing multicellular glass is a base mateiral with lower soda-lime glasss of softening temperature such as dull and stereotyped and Bottle ﹠ Cans mainly, add again an amount of whipping agent (Tian Yingliang, Qu Peiyuan. glass and enamel, 2002,30 (5): 49-51).Whipping agent is generally carbon black, lime carbonate etc.Mainly utilize the oxidation and the decomposition reaction of whipping agent, discharge gas and in glass, form bubble.According to the difference on the foamed glass blank annealing way, the multicellular glass production technique is divided into " two step method " and " single stage method ", most of manufacturers all adopt " two step method " technology.Be characterized in the foaming and setting later stage, outside kiln,, focus in the annealing furnace again and anneal after the high temperature steel mould removal.This method unfavorable factor is, the stripping operation condition poor (Tian Yingliang, Qu Peiyuan. glass and enamel, 2002,30 (5): 49-51).Present stage, there were many shortcomings in the hole that produces of the foaming that adopts, and for example pore size differs, and the multicellular glass of macropore is difficult for producing, and produced block sintered glass and need knockout course, complicated operation.
Summary of the invention:
The object of the present invention is to provide a kind of wide-aperture porous foam glass and preparation method thereof.The preparation method adopts conventional sintering process, and the powder of selecting for use scrap glass to grind to form is a basic material, and selecting the particulate state porous plastics for use is the pore-creating thing, has prepared porous multicellular glass.
The present invention uses scrap glass to be raw material, can significantly reduce production costs, and can handle scrap glass for glass production enterprise, helps environment protection.
Pore-creating thing of the present invention is the particulate state porous plastics, is characterized in cheap, obtains easily, and can realize the control more accurately to bore hole size and distribution by fill the hole that particles of different sizes obtains different size in glass powder.
Thermal treatment process of the present invention is: powder and particulate state porous plastics that scrap glass is ground to form add the water uniform mixing, after the moulding, put into retort furnace, 100～120 ℃ of insulation for some time, moisture is dried, subsequently temperature slowly is raised to 600～900 ℃ (actual temp is determined by glass types), is incubated 30 minutes, naturally cool to room temperature at last.
The multicellular glass of the present invention's preparation has following advantage:
1) hole is evenly distributed, and aperture size is big, and hole interconnects.
2) moulding is simple, only need or not the high temperature demoulding in room temperature compression moulding.
3) can under the situation of not cutting, prepare the multicellular glass of various special shapes.
4) equipment is simple, and raw material obtains easily, and is easy to operate.
Description of drawings:
The outward appearance photo of Fig. 1 example 1 porous foam glass of the present invention, external form is the porous spheroid.
The details photo of Fig. 2 example 1 of the present invention can be found out that hole is evenly distributed, and interconnect between hole.
The outward appearance photo of Fig. 3 example 2 porous foam glass of the present invention, external form is a porous blocks.
The details photo of Fig. 4 example 2 of the present invention can be found out that hole is evenly distributed, and interconnect between hole.
Embodiment:

4) mixture of glass powder and foam beads is put into jarring machine,, form spheroid through vibrations.
5) block is put into retort furnace, 110 ℃ are incubated 1 hour, oven dry moisture.
6) temperature is warming up to 650 ℃ with the speed of 15 ℃/min, is incubated 40 minutes.
7) the glass finished product that makes is taken out from stove, naturally cool to room temperature.
Embodiment 2:
1) be that glass fragment is developed into powder with Li-Zn-Si.
2) measure the porous plastics spheroidal particle that the 150ml diameter is 1～2mm (the about 2.4g of gross weight), add 60ml water, stir.
3) 60ml glass powder (heavily about 47.0g) is joined in the moistening foam beads, fully stir, make glass powder and foam beads uniform mixing.
4) mixture of glass powder and foam beads is put into 7 * 7 * 2cm steel die, be compacted into block.
5) block is put into retort furnace, 110 ℃ are incubated 1 hour, oven dry moisture.
6) temperature is warming up to 900 ℃ with the speed of 15 ℃/min, is incubated 30 minutes.
