Abstract

The invention belongs to the technical field of paint film detection, in particular to a rapid detection method of the glossiness of wood paint. The method comprises the following steps: S1, materialtreatment: drying a wood paint sample to be detected in a 75 to 80 DEG C drying oven; S2, sample manufacture: grinding the surface of a wood sample, then cleaning the wood sample, and spraying dried wood paint onto the surface of the wood sample; S3, drying: drying the manufactured sample for 4 to 5 hours in a constant temperature and constant humidity environment; S4, detection: measuring the dried sample for 3 to 5 times through a digital glossmeter, and finally taking a measured average value. The rapid detection method reasonably controls the drying time and drying humidity, improves the detection accuracy, greatly shortens the detection time, improves the production efficiency, and is low in cost and convenient to operate.

Description

Technical field [0001] The invention relates to the technical field of paint film detection, in particular to a method for quickly detecting the gloss of wood lacquer. Background technique [0002] Wood paint refers to a type of resin paint used on wood products, including polyester, polyurethane paint, etc., which can be divided into water-based and oily. According to gloss, it can be divided into high gloss, semi-matte and matte. According to the purpose, it can be divided into furniture paint, floor paint, etc. Natural wood lacquer is commonly called big lacquer, and also known as "national lacquer". The sap cut from the sumac tree is called Maosheng lacquer or original bucket lacquer, and the impurities are filtered out with white cloth called raw lacquer. In the production process of wood lacquer, the gloss of wood lacquer needs to be tested. The existing wood lacquer gloss detection method takes a long time, the detection accuracy is low, and the cost is too high. We pro...
