Problems solved by technology

[0002] At present, barium cement protective coatings are widely used in the market. The proportion of the coatings should not be mastered, and it is prone to cracking, falling off, and poor durability.
In addition, lead plate is used for protection, but its construction is difficult, soft, toxic, easy to reproduce creep after a long time, and will cause scattered rays.

Embodiment 1

[0015] Adopt formula as follows:

[0016] 1. Iron oxide 200kg, particle size 0.1mm-1.3mm. Because of its soluble acidity and barium sulfate (barite) have a good chemical reaction.

[0017] 2. Wolframite 80kg, particle size 0.1mm-0.3mm, hardness 5-5.5, specific gravity 7.1-7.5. It has a good shielding effect on radioactive substances.

[0018] 3. Rectorite ore 100kg, the minerals are mainly rectorite, the particle size is 100-200 mesh, and the rectorite content is > 42%. Rays have strong absorption.

[0019] 4. Barium sulfate (barite) 500kg, particle size 0.1mm-2.0mm, barite should meet JGJ53-92 standard, apparent density ≥ 3.79t / m 3 , loose density ≥ 2.08t / m 3 , containing barium ≥ 80%. It has a relatively strong absorption effect on X-rays.

[0020] 5. Iron sulfate 15kg, particle size 1.0mm-1.5mm, used as catalyst.

[0021] 6. 250kg of cement, used as a binder.

[0022] 7. Borax 10kg, boiling point: 1575°C, melting point: 320°C, specific gravity 1.73, has moderating ...

Embodiment 2

[0029] Adopt formula as follows:

[0030] 1. Iron oxide 250kg, particle size 0.1mm-1.3mm. Because of its soluble acidity and barium sulfate (barite) have a good chemical reaction.

[0031] 2. Wolframite, (FeMn)WO4, 30kg. Particle size 0.1mm-0.3mm. Hardness 5-5.5, specific gravity 7.1-7.5. It has a good shielding effect on radioactive substances. Because of its corrosion resistance, it does not interact with acid salts or sulfuric acid, and can balance the excessive combination of barium sulfate and ferric sulfate with iron oxide and rectorite.

[0032] 3. Rectorite ore 60kg, particle size 100-200 mesh, minerals are mainly rectorite, content> 42%, rectorite has the characteristics of high temperature resistance, rectorite refractoriness reaches 1660 ℃; Strong absorption.

[0033] 4. Barium sulfate (barite) 500kg, particle size 0.1mm-2.0mm, barite should meet JGJ53-92 standard, apparent density ≥ 3.79t / m 3 , loose density ≥ 2.08t / m 3 , barium content ≥ 80% or more (bariu...

Abstract

The invention belongs to the inorganic non-metallic material field, disclosing a radiation proof composite paint formulation. The radiation proof composite paint of the invention is formed by the following compositions, 15-25wt% ferric oxide whose grain size is 0.1mm-1.3mm, 2.7-8wt% tungsten ore powder whose grain size is 0.1mm-0.3mm, 4-10wt% rectorite ore whose grain size is 100-200 mesh, 40-50wt% barium sulfate whose grain size is 0.1mm-2.0mm, 0.7-1.3wt% ferric sulfate whose grain size is 1.0mm-1.5mm, 20-50wt% cement and 0.5-0.9wt% borax. The radiation proof composite paint of the inventionhas the advantages of environmental protection, convenient construction and firm bonding.

Description

technical field [0001] The invention belongs to the field of inorganic non-metallic materials, and specifically refers to a coating. Background technique [0002] At present, barium cement protective coatings are widely used in the market. The proportion of this coating should not be mastered, and it is prone to cracking, falling off, and poor durability. In addition, lead plate is used for protection, but its construction is difficult, soft, toxic, easy to reproduce creep after a long time, and will cause scattered rays. Contents of the invention [0003] Aiming at the technical defects of the above-mentioned background technology, the present invention provides an anti-radiation coating that is environmentally friendly and convenient for construction. The technical scheme adopted in the present invention is as follows: a radiation-proof composite coating, which is formed by mixing various heavy metal compounds such as iron oxide, tungsten ore powder, drag stone ore, bar...
