Problems solved by technology

However, the inventors have found in long-term practice that these characterization methods have a long test period and cannot meet the requirements of large-scale and standardized testing.
What's more, the above method cannot simulate the performance of the paint film under wet conditions, and this performance can just comprehensively reflect the water resistance and flexibility of the paint film, which is one of the necessary conditions for later screening

Embodiment 1

[0102] Embodiment 1: water-based wood paint test

[0103] Installation of the device:

[0104] 1. Water mist launch device:

[0105] (1) The operation panel is used to control the water mist volume and temperature of the device, and the power switch of the water mist emitting device. The amount of water mist is divided into two levels of 280-380mL / h and 320-420mL / h; the temperature control is divided into two levels of water mist at room temperature and water mist at 40°C;

[0106] (2) Water mist launch port, water mist is emitted from the launch port, and the launch port needs to be tightly connected with the bracket to prevent air leakage;

[0107] (3) Filtration device, used to filter impurities in water mist.

[0108] 2. A metal multi-slot fixture frame for inserting four 30×40cm templates with a thickness not exceeding 5mm, and one 30×30cm template with a thickness not exceeding 5mm.

[0109] 3. The bottom support of the fixture frame must be fully enclosed to accept ...

Abstract

The present invention provides a test apparatus for the moisture resistance of an aqueous wood lacquer, particularly a qualitation apparatus for rapidly determining the water resistance of an emulsion and the flexibility of a paint film. According to the present invention, the apparatus can well simulate the conditions of high moisture and a certain temperature, can test the water resistance of the aqueous wood lacquer and the flexibility of the paint film, and can provide the relevant basis for the research and development of the aqueous wood coating material and the early rapid screening of the emulsion.

Description

technical field [0001] The invention relates to the field of wood paint testing, in particular, the invention provides a device for quickly testing the water resistance of emulsion and the flexibility of paint film at an early stage. Background technique [0002] In addition to its decorative effect, wood lacquer also needs to have a certain protective effect on wood. In recent years, there are more and more kinds of water-based wood paints on the market. Due to the advantages of environmental protection, major brands in the market have launched their own water-based products, and the competition between products has become increasingly fierce. Although relevant testing standards have corresponding testing methods for water resistance and paint film flexibility, these methods have a long test cycle and cannot quickly, efficiently and comprehensively judge the usability of emulsions. [0003] At present, in the performance test of water-based wood coatings, the method stipul...
