Method used for measuring tensile performance of waterproof paint in cement

Abstract

The invention discloses a method used for measuring tensile performance of waterproof paint in cement. According to the method, a tensile test machine, a slicing machine, a thickness meter, an electrothermal blowing dry box, an ultraviolet ray ageing oven, and an artificial accelerating weathering aging box are adopted; appropriate amounts of a liquid component and a solid component are taken, aremixed, are subjected to mechanical stirring, and are introduced into a film coating die for coating, the surface of the film coating die is processed with silicone oil or paraffin, in sample preparation process, in 72h, the sample thickness is increased to be (1.5+/0.2)mm, after sample demoulding, the sample is allowed to stand for 168h at standard conditions, is subjected to 24h of processing ina (50+/-2) DEG C drying box, is taken out from the drying box, and is introduced into a dryer; the slicing machine is adopted to slide the sample into pieces with the shape and the number required bythe tensile test; and the tensile performance of samples without processing, after thermal processing, after alkali processing, and after ultraviolet ray processing is measured; and result calculation is carried out. The method is capable of realizing accurate test of the tensile performance of polymer cement waterproof paint, and is convenient for subsequent using.

Description

technical field [0001] The invention relates to a method, in particular to a method for measuring the tensile properties of waterproof coatings in cement. Background technique [0002] Paint, traditionally called paint in China. The so-called paint is coated on the surface of the object to be protected or decorated, and can form a continuous film firmly attached to the object to be coated, usually based on resin, oil, or emulsion, with or without adding pigments, fillers, adding The corresponding additives are viscous liquids prepared with organic solvents or water. The relatively authoritative book "Painting Technology" in the Chinese coatings industry defines it as follows: "Painting is a material that can be coated on the surface of an object by different construction techniques to form a firm adhesion, a certain strength, and a continuous coating. Solid film. The film formed in this way is commonly called coating film, also known as paint film or coating.” Coating, wha...
