Description
Technical field
The present invention relates to high strength glass production technical field, be specifically related to formula and the preparation work of a kind of high intensity plate glass
Skill.
Background technology
The theoretical strength of ordinary plate glass is the highest, but actual strength is relatively low, low 2～3 orders of magnitude than theoretical strength.
In order to obtain former of high strength glass, current countries in the world are all that the method for employing plate glass secondary deep processing is strong to improve glass
Degree, the method for secondary deep processing can be summarized as three below aspect: one is to cause compression prestress at glass surface；Two is to change
Kind glass surface quality；Three is the comprehensive enhancement techniques that both combine.
Details are as follows respectively:
One, physics, the chemically or physically method of chemistry is used to cause compression prestress to improve strength of glass at glass surface.Wherein table
The physical method of face quenching tempering, such as common air hardening steel, its intensity is up to 120～250Mpa；Liquid toughening, its intensity can
Reach 150～350Mpa.Chemical method therein, such as the method exchanged with ion, its intensity up to 500～1000Mpa,
Or physico-chemical process, i.e. it is also carried out ion exchange at tempering simultaneously.
Two, glass surface quality is improved.As used flame polish method, strength of glass is up to 70～180Mpa；Carry out with acid
Chemical polishing, then up to 1000～2000Mpa, but so treated, dust and the moisture pollution to glass in process environments,
The glass surface improved will necessarily be damaged, for that purpose it is necessary to take special measure that it is protected immediately, otherwise, carry
The intensity of high glass will decline to a great extent.
Three, both the above method engages, and i.e. forms surface precommpression stress, also improves the comprehensive enhancing of surface quality simultaneously
Technology, the intensity of its reinforcing glass is up to 1500～2500Mpa.But this method is the same with Section 2, to the glass strengthened
Special measure must be taked to protect it immediately, and otherwise, its intensity is by the most significant decline.
The method of above reinforcing glass is all mended the fold after the sheep is lost.They are required for that original sheet glass carries out secondary reprocessing again and process,
Not only technique, equipment complexity, need the newest human and material resources and the input of financial resources, high energy consumption, and, some technique is such as
The noise of tempering, the Korrosionsmedium of acid treatment are the most harmful to health and bad border.On the other hand, although having spent the most energetically
The reinforcing glass that gas is obtained, its reinforced effects is unsatisfactory, still falls far short with its theoretical strength, and best manages also less than it
/ 10th of opinion intensity.
Polydiphenyl ether resin is thermosetting polymer.It has high temperature resistant, radiation hardness and excellent mechanical electric performance.But
Owing to its solidification temperature is high, moulded manufacturability is poor, the most generally individually use biphenol modification diphenyl ether as composite
Matrix resin.Diphenyl ether after phenol-modified has the features such as low cost, solidification temperature be low, is widely used in recent years
In the preparation of glass cloth laminated board, but manufacture in a rough and slipshod way more at present, phenol-modified diphenyl ether laminate at a low price is commercially gone
Pin for the moment, the normal market order of very disruptive, and add the Fe of certain content in the most domestic high strength glass2O3,
Make diathermancy and the color the most defect of glass.
Summary of the invention
For problem above, the invention provides formula and the preparation technology of a kind of high intensity plate glass, by glass
With the addition of polydiphenyl ether resin, founded by platinum-rhodium crucible, operate with cooling etc. through stirring, clarifying, obtained high intensity
Glass, is worthy to be popularized.
To achieve these goals, the technical solution used in the present invention is as follows: polydiphenyl ether resin 30-40 part, silicon dioxide
