Abstract

The invention provides a paint film standard substance. The standard substance is prepared by adding a solvent, filler, white lead and lead chromate into acrylic resin paint and carrying out uniform stirring and mixing through stirring equipment. A preparation process of the paint film standard substance includes the steps that firstly, the solid content of wet paint is calculated; then a proper amount of wet paint is put in a container containing a proper amount of solvent, white lead and lead chromate with corresponding contents are put according to the solid content of the wet paint and the lead content needing to be manufactured, and the materials are stirred for 2-3 hours; the stirred wet paint mixture is evenly smeared on a base material; the base material on which the wet paint mixture is smeared is put in an air box to be dried; the dried base material is taken out, a paint coating is shoveled from the base material, the paint coating is ground and then screened, and the materials are fully mixed to be uniform. According to the preparation process, the paint film standard substance can be prepared rapidly and simply, precision is high, uniformity is good, and the stability of the prepared paint film standard substance is high.

Description

technical field [0001] The invention belongs to the field of lead-containing paint reference materials, and in particular relates to a paint film reference material, a preparation process and a stirring device used in the preparation. Background technique [0002] Among the many "culprits" that endanger human health and children's intelligence today, lead is one of the most harmful. According to an authoritative survey report, the average lead content in the modern human body has greatly exceeded 500 times that of the ancients 1000 years ago! Human beings lack active and effective protective measures. According to the survey, the average lead content in many children's bodies is generally higher than that of young people; after lead enters the human body, except partly excreted through feces and sweat, the rest dissolves into the blood after a few hours, hindering the synthesis of blood, leading to anemia in the human body. Headache, dizziness, fatigue, drowsiness, constip...
