Problems solved by technology

The composition of ordinary glass cannot effectively absorb such rays, and a large number of elements with high atomic numbers must be introduced into the glass composition to improve its absorption capacity. However, adding anti-radiation substances directly to the glass will not only result in a higher overall glass cost, but also Moreover, in the process of glass preparation, uneven distribution of anti-radiation substances is prone to occur, which in turn leads to uneven distribution of anti-radiation properties of peeling
[0003] In the existing technology, in order to reduce costs, a layer of anti-radiation film is usually directly compounded on the surface of the glass, but under long-term use, the anti-radiation film is prone to scratches and peeling off under the action of external force, which not only affects the appearance of the glass , and makes the radiation resistance of the stripping decrease at the same time

Abstract

The invention discloses a thermal insulation anti-radiation laminated glass film, which comprises the following components by weight: 73-79 parts of high strength epoxy resin, 6-7 parts of a perfluoroalkyl ether quaternary ammonium salt, 5-8 parts of polyether silicone oil, 16-18 parts of silica sol, 26-28 parts of a boron-rich curing agent and 210-220 parts of dimethyl sulfoxide. According to theinvention, a film laminating agent with anti-radiation and low heat conduction properties, then the film laminating agent is coated between two layers of glass for bonding and fixing the two layers of glass, so that a glass film can be formed between the two layers of glass, the glass film itself has anti-radiation and thermal insulation properties, and then the prepared double-layer glass has high anti-radiation and thermal insulation properties, at the same time through the protection of the two layers of glass, the glass film therein cannot be scratched or peeled under the action of an external force, and then the service life of thermal insulation anti-radiation glass can be improved.

Description

technical field [0001] The invention belongs to the field of glass film preparation, and relates to a heat-insulating and anti-radiation laminated glass film and a production process thereof. Background technique [0002] Radiation-resistant glass refers to special glass that has the function of protecting radioactive rays such as x-rays and gamma-rays. Radioactive rays are all high-energy electromagnetic waves. When the rays pass through different media, they can cause the atoms in the media to ionize. The shorter the wavelength of the electromagnetic wave, the stronger its penetrating ability. Since the wavelength of the ray is of the same order of magnitude as the size of the atom, the molecular absorption coefficient can be obtained by adding the atomic absorption coefficients of the elements that make up the molecule. Therefore, the mass absorption coefficients of various oxides that make up glass can be calculated according to this principle. The composition of ordin...
