Description
Technical field
The present invention relates to, with the Vegetable oil lipoprotein lacquer tree fat of natural reproducible as raw material, utilize polyacrylic acid that it is modified
To high performance polyacrylic monomer modified large arch dam lacquer tree fat emulsion, may be used for material waterproofing, coating, the agricultural neck such as waterproof
The preparation method of the lacquer tree fat emulsion in territory.
Background technology
Toxicodendron verniciflnum (Stokes) F. A. Barkley (Rhus verniciflua Stokes) refers mainly to Anacardiaceae, paint belongs to the class plant of (Toxicodendron), be the traditional economic forest of China it
One, its cultivation history is long, and variety source enriches, and is claimed because a kind of lacquer (i.e. Resina Toxicodendri verniciflui) of secretion has the Optimality of uniqueness
For state's paint or lacquer, enjoy great prestige both at home and abroad.The fruit of Toxicodendron verniciflnum (Stokes) F. A. Barkley (Rhus verniciflua Stokes) is also known as paint seed, and in flat the most spherical, annual 9 ~ October of autumn is ripe.Really
Skin divides 3 layers, outer peel film quality；Mesocarp is wax coat, can extract lacquer tree fat, for light yellow or celadon；Kernel is seed, can squeeze
Take urushoil.Lacquer tree fat chemical composition by 90%～95% triglyceride, 3%～15% free fatty, 1%～2% free alkyl alcohol form,
Wherein conjugated fatty acid is by 70%～75% Palmic acid, 3%～5% stearic acid, 15%～35% oleic acid, 2%～5% binary of fatty acids group
Become.Because it has the dicarboxylic acid component of uniqueness, giving and paint higher elasticity and pliability, having general vegetable wax is not had
