Abstract
The invention relates to the technical field of industrial wax, in particular to a wax material for preparing hippeastrum corm and a preparation method thereof, wherein the wax material comprises the following raw materials in parts by weight: 40-60 parts of petroleum wax, 5-10 parts of mineral oil, 20-30 parts of petroleum resin, 1-3 parts of POE (polyolefin elastomer), 1-3 parts of SEBS (styrene-ethylene-butadiene-styrene) elastomer, 78-3 parts of PE (polyethylene) 1 and 2-6 parts of dammar resin. The wax material has the advantages of good stability, high solid content, small viscosity, difficulty in dewaxing, low cost, environment-friendly components, no harm to the environment and human bodies, repeated use for many times, direct, rapid and accurate forging of high-quality hippeastrum corms, simplified wax mold manufacturing procedures, shortened period and improved working efficiency; the method for preparing the wax material has the advantages of simple operation, convenient control, high production efficiency and low production cost, and is beneficial to industrial production.
Description
Technical Field
The invention relates to the technical field of industrial wax, and particularly relates to a wax material for manufacturing hippeastrum corm and a preparation method thereof.
Background
Hippeastrum rutilum also refers to red lotus (Hainan plant), armature blue (North China economic plant), armature stomach, baizhilian, top red, Hippeastrum red, flower of lonely, armature blue, baizi lotus, baizhilian, red, etc. Is perennial herb of genus hippeastrum of family Amaryllidaceae.
