Abstract

The invention discloses a preparation method of anti-radiation putty powder, relating to the technical field of building materials. The method comprises the following steps: A, mixing gypsum, talc, silver, barium, boride and peach gum to obtain a first mixture, and crushing the first mixture into a particulate material by a crusher, wherein the diameter of the particulate material is less than 30 millimeter, and the power of the crusher is 55-130kw; B, pulverizing the particulate material into powder by a pulverizer, wherein the rotational speed of the main engine of the pulverizer is 90-130 turn/min; C, sieving the powder by 300-500 meshes, and clearing away the powder greater than 300-500 meshes; mixing white low heat portland cement and carboxymethylcellulose into the sieved mixed powder, and stirring uniformly, thus obtaining the putty powder, wherein the stirring rate is 500-800 turn/min, and the stirring time is 15-25min. Compared with the prior art, the preparation method has the functions of preventing magnetism, preventing rays and preventing neutron radiation.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a preparation method of anti-radiation putty powder. Background technique [0002] Putty powder is a kind of building decoration material. A layer of white substance brushed on the surface of the rough room just purchased is putty powder. It is a thick paste paint and an indispensable product before other paints are painted. Applied on the primer or directly on the object to remove uneven defects on the surface of the object to be coated. The general putty is made of gypsum, lime calcium and carboxymethyl cellulose, which is waterproof. [0003] Modern people are exposed to a variety of radiation environments, including electromagnetic radiation from household appliances such as mobile phones, televisions, computers, and microwave ovens; ray radiation and neutron radiation from medical devices. Patent application number: 201310467675.2 discloses anti-radiation putty ...
