Soft damage resistance testing method

Abstract

The invention discloses a soft damage resistance testing method. The soft damage resistance testing method comprises: testing the initial luster of a to-be-tested area of a to-be-tested piece; putting the to-be-tested piece on a sample base plate, and fixing the to-be-tested piece; driving the sample base plate to move the to-be-tested piece to one end of a base through a driving device; fixing a soft damage medium on a lower surface of a load device; moving a load positioning device to the to-be-tested area of the to-be-tested piece, and fixing the load positioning device; installing the load device on the base, and making the soft damage medium come into contact with the to-be-tested piece; driving the sample base plate to move relative to the load device through the driving device; driving the sample base plate to return to an initial position by the same way through the driving device; testing the endpoint luster of a rubbed area of the to-be-tested piece; evaluating the mechanical property of a material through the endpoint luster and the initial luster. The method is simple and convenient in operation, a complicated sample pretreatment requirement is avoided, testing medium varieties are easily replaced, the test area is large, and the method is suitable for qualitative and quantitative characterization.

Description

technical field [0001] The invention relates to the field of manufacture and application of surface coating materials for wooden floors, wooden furniture and other wooden products, in particular to a method for testing the anti-soft damage performance. Background technique [0002] During the actual use of wood coatings, it is inevitable that they will be worn to varying degrees, causing damage or loss of gloss to the paint film, which affects the appearance and use effect of the paint film and shortens the usable time of the paint film. Therefore, when developing wood coatings, relevant instruments and equipment are needed to evaluate the performance to ensure that the product has certain durability and application performance. [0003] At present, the test device for testing the damage of the paint film of wood coatings through abrasion is the Taber abrasion meter, which rubs a local area of ​​the paint film through a contact end with a certain load, and qualitatively eval...

AI Technical Summary

Problems solved by technology

[0004] First, the damage medium for testing is not easy to obtain, and needs to be customized according to the specified specifications;

[0005] Second, the test area is small and cannot be evaluated in more dimensions;

[0006] Third, it is impossible to provide test evaluation of soft injury performance;
