Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces LY/T 1179-1995 "rosin modified phenolic resin (210 resin)", compared with the main LY/T 1179-1995
The changes are as follows.
--- Standard title deleted (210 resin);
--- Chapter 2 added LY/T 1453-2010 reference; canceled GB/T 601, GB/T 6682 of the reference;
GB/T 9281.1-2008 alternative GB/T 1722-1992;
--- Added Chapter 3 rosin modified phenolic resin terms and definitions;
--- Chapter 4 in Table 1 to modify the level for the category, modify the appearance of the statement, extended to 185 ℃ softening point, solubility
Increased no mechanical impurities and sediments, improve the product quality requirements;
--- Chapter 5 increased the appearance of the determination method, acid value, solubility determination method for the direct reference.
This standard was proposed by the State Forestry Administration Science and Technology Division.
This standard by the Chinese Academy of Forestry Forest Chemical Industry Institute.
This standard is drafted by. Forest Research Institute of China Academy of Forestry Chemical Industry Institute.
The main drafters of this standard. Liu Hongjun, Zhou Yonghong, Hu Lihong, Zhang Meng.
This standard replaces the standards previously issued as follows.
--- LY/T 1179-1995.
