Abstract
Description
Technical field
[0001] The invention relates to a soft microcrystalline wax composition, which can effectively improve the defects of ordinary microcrystalline wax, such as poor toughness and easy brittleness, and is particularly suitable for use in the fields of moisture prevention, insulation, sealing, and craft candles. Background technique
[0002] Microcrystalline wax, especially soft microcrystalline wax, is an important raw material for medicine, daily chemical industry and other fine chemical products. Ordinary microcrystalline waxes are mostly hard microcrystalline waxes. The penetration degree at 25°C is generally 8~18 1 / 10mm. It is easy to be brittle and has poor plastic deformation performance. It is easy to crack and fall off at low temperature, which affects its moisture resistance and insulation. And sealing performance. The production process of ordinary microcrystalline wax is generally obtained by solvent deasphalting, solvent refining, solvent dewaxing and deoi...
