Embodiment 1

[0021] A core material for a radiation-proof and heat-insulating board, comprising the following raw materials by weight: 45 parts of expanded perlite, 2 parts of carbon black, 3 parts of fumed silica, 1 part of fly ash, 8 parts of glass fiber wool produced by centrifugal method, 8 parts of glass fiber cotton, 0.5 parts of lead, 2.5 parts of barium, 1 part of cadmium and 3 parts of tin produced by flame method.

[0022] The preparation method is:

[0023] (1) Take the glass fiber wool produced by the centrifugal method and the glass fiber wool produced by the flame method, add the two kinds of glass fiber wool with water and stir to dilute the concentration to 0.2%, and then add the corresponding proportions of expanded perlite, silica fume, and shielding materials. form a slurry;

[0024] (2) The slurry is sent to the slurry storage tank for 2 hours, then the slurry in the slurry storage tank is sent to the head box, and the slurry is dehydrated and formed into a core materi...

Embodiment 2

[0030] The preparation method is the same as in Example 1, the difference is that the core material of the radiation-proof and heat-insulating board is composed of the following raw materials by weight: 48 parts of expanded perlite, 4 parts of carbon black, 2 parts of fumed silica, and fly ash 4 parts, 10 parts of glass fiber wool produced by centrifugal method, 10 parts of glass fiber wool produced by flame method, 1 part of lead, 2.5 parts of barium, 1.5 parts of cadmium, and 3.5 parts of tin.

[0031] After testing, the thermal conductivity of the core material is 1.5mW / m.k. The wave radiation of 200mT magnetic induction intensity is used on one side, and the magnetic induction intensity of the other side is 5mT, which can effectively reduce electromagnetic radiation.

Embodiment 3

[0033] The preparation method is the same as in Example 1, except that the core material of the radiation-proof and heat-insulating board is composed of the following raw materials by weight: 46 parts of expanded perlite, 2 parts of carbon black, 4 parts of fumed silica, and fly ash 1 part, 9 parts of glass fiber cotton produced by centrifugal method, 9 parts of glass fiber cotton produced by flame method, 1 part of lead, 2.5 parts of barium, 1.5 parts of cadmium, and 3.5 parts of tin.

[0034] After testing, the thermal conductivity of the core material is 1.6mW / m.k. The wave radiation of 200mT magnetic induction intensity is used on one side, and the magnetic induction intensity of the other side is 6mT, which can effectively reduce electromagnetic radiation.

Abstract

The invention discloses an anti-radiation thermal insulation slab core material. The anti-radiation thermal insulation slab core material comprises, by weight, 45-48 parts of expanded perlite, 5-10 parts of silica fume, 15-20 parts of reinforcing fibers and 5-10 parts of shielding materials. The core material is obtained after the procedures of slurry preparation, blank preparation, blank leveling, vacuum dehydration, drying and cutting are conducted on raw materials. The anti-radiation thermal insulation slab core material is good in heat resistance, low in heat conductivity coefficient, capable of effectively shielding outside electromagnetic radiation sources and long in service life, and the effective life of the anti-radiation thermal insulation slab core material can reach 20 years.

Description

technical field [0001] The invention relates to a core material of an anti-radiation heat insulation board and a preparation method, and belongs to the field of building materials. Background technique [0002] With the further development of electrical equipment technology, radiation can be seen everywhere around us, whether it is mobile phones, computers, printers and scanners at work, or microwave ovens, electric blankets, hair dryers, TVs, refrigerators, Air conditioners, vacuum cleaners; and natural radiation such as medical equipment, TV towers, high-voltage lines, electrical substations, and sunspots. People who work, study and live in an environment with concentrated radiation sources are prone to insomnia and dreams, memory loss, physical weakness, and low immunity. [0003] At present, in the application field of thermal insulation boards, the focus is on the thermal resistance and thermal conductivity of home appliance insulation, building exterior wall insulatio...
