Problems solved by technology

But so far organic lead glass still has the disadvantages of low surface hardness, poor scratch resistance, and easy fluffing on the surface.
The organobarium macromolecule material of high hardness has been reported, but to the synthetic method of barium methacrylate, the research of polymerization process condition and performance is not sufficient yet, the organobarium glass of synthesizing barium methacrylate content more than 8% still has It must be difficult, too much barium methacrylate will cause the plate to lose its transparency

Embodiment 1

[0020] A barium glass material prepared from the following raw materials according to the stated weight (Kg), SiO 2 :67;B 2 o 3 : 1.70; Al 2 o 3 : 1.00; CaO: 3; ZnO: 1.80; BaO: 8; K 2 O: 4; Na 2 O: 13.

[0021] The specific production method of barium glass material is: from heating the raw material to melting the molten glass, it can be divided into the following five stages according to the different melting processes: The first stage of silicate formation: during the heating process, the raw material SiO 2 :67;B 2 o 3 : 1.70; Al 2 o 3 : 1.00; CaO: 3; ZnO: 1.80; BaO: 8; K 2 O: 4; Na 2 After the composition of O:13 undergoes chemical and physical changes, most of the gas products have been developed. At this stage, the main reaction process of glass melting is completed, and the glass raw materials are converted into silicate and SiO 2 Composed of opaque sintered products; and for the produced soda-lime-silica glass, the temperature at this stage is completed at 8...

Abstract

The invention relates to glass, in particular to barium glass. A barium glass material is prepared from the following raw materials in part by weight: 67 parts of SiO2, 1.70 parts of B2O3, 1.00 part of Al2O3, 3 parts of CaO, 1.80 parts of ZnO, 8 parts of BaO, 4 parts of K2O and 13 parts of Na2O. The barium glass material has a reasonable formula and is not prepared from the conventional barium methacrylate, so that the transmittance of the glass is greatly improved; the barium glass material has high low-energy X-ray shielding property; and the prepared barium glass has high surface hardness,high mechanical strength, solvent resistance, high light permeability and wide application.

Description

technical field [0001] The present invention relates to glasses, especially barium glasses. Background technique [0002] In the fields of industrial and agricultural production, national defense, atomic energy and radiation medicine, there is a need for a special plastic with excellent χ, γ-ray shielding function and good light transmission performance. Since the late 1970s, organolead glass has been extensively researched and applied. But so far organic lead glass still has disadvantages such as low surface hardness, poor scratch resistance, and easy fluffing on the surface. The organobarium macromolecular material of high hardness has been reported, but to the synthetic method of barium methacrylate, the research of polymerization process condition and performance is not sufficient yet, the organobarium glass that synthetic barium methacrylate content is more than 8% still has It must be difficult, too much barium methacrylate will cause the plate to lose its transparen...
