Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard proposed by the State Forestry Administration. This standard by the National Panel Standardization Technical Committee (SAC/TC198) centralized. This standard drafting unit. Chinese Academy of Forestry Timber Industry Institute, Zhejiang Jindi Door Co., Ltd., Jiangsu Hai Tian Technology Limited, the State Building Decoration Materials Quality Supervision and Inspection Center, Guangdong Huilong Paint Co., Ltd., Clivia Chemical (Shanghai) Co., Ltd., Canton Dongrun into a show Wood Co., Ltd., Henan Yongwei Security Co., Ltd., Guangdong Institute of product quality supervision and inspection.

Wood products with UV-curable coatings Volatile content detection method

1 Scope

This standard specifies the wood products with UV (UV) curing coatings (hereinafter referred to as UV coatings) Determination of volatile content. This standard applies to wood-based panels, wooden doors, wood flooring and other wood products coated with non-aqueous UV coating.

2 Terms and definitions

The following terms and definitions apply to this document. 2.1 UV curable coatings ultravioletcurablecoatings In UV light irradiation, UV liquid paint in the photoinitiator excited by the change into free radicals or cations, which led to the paint with Reactive substances occur between the chemical reaction, eventually leading to the formation of three-dimensional structure, so that paint curing. 2.2 Volatile content during finishing processingvolatilescontent Simulation of the actual industrial curing conditions, the UV coating by UV light radiation curing, the quality of the sample curing process loss. 2.3 Potential volatile content potentialvolatilescontent The cured UV coating samples were placed in a (110 ± 2) ℃ oven heated 1h, the sample was measured for mass loss. 2.4 Total volatile content totalvolatilescontent The sum of the volatile content and the potential volatile content of the finishing process.

3 test methods

3.1 Volatile total content of less than or equal to 3% of the test method 3.1.1 principle Weigh the quantitative UV coating samples, simulated industrial processing methods will be applied to the aluminum substrate, and then weighed aluminum substrate quality, with purple External light irradiation test sample curing, weighing UV coating process of coating the volatile content; the cured sample after cooling Heat in a (110 ± 2) ° C oven for 60 min and calculate the potential volatiles content by mass loss, the sum of the two being the UV coating volatiles Total content. 3.1.2 instruments and equipment The required equipment and equipment are as follows. a) Aluminum (305mm × 102mm) or without plastic foil (thickness not less than 0.05mm). Note. For ease of operation and weighing, cut an aluminum plate of the same size as three aluminum plates as a test plate (the size of the test plate should be guaranteed to be a minimum of 0.2 g UV coating, to meet the coating thickness provided by the supplier requirements), before use, the cut test sample into the (110 ± 2) ℃ dryer ......
