▎ 摘 要
NOVELTY - Ammonia-free phenolic molding compound comprises 60-100 pts. wt. phenolic resin, 10-30 pts. wt. melamine formaldehyde resin, 5-10 pts. wt. urea formaldehyde resin, 1-5 pts. wt. calcium oxide, 20-40 pts. wt. inorganic filler, 40-80 pts. wt. reinforcing fiber, and 1-5 pts. wt. lubricant. USE - Used as ammonia-free phenolic molding. ADVANTAGE - The molding: has high temperature resistant, high strength, and no ammonia residue. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing ammonia-free phenolic molding compound comprising placing phenolic resin, melamine formaldehyde resin, urea formaldehyde resin, calcium oxide, inorganic fillers, reinforcing fibers and lubricants into an open plastic mixer for kneading, the temperature of the operating roller of the open type plastic mixer is 90-110 degrees C, the temperature of the heating roller is 140-150 degrees C, the distance between the rollers is 3-4 mm, and the mixing time is 5-6 minutes.
