Abstract

The invention discloses an imitation porcelain bottle, the raw materials of which include by weight: 100 parts of filler, 10-15 parts of melamine formaldehyde resin, 30-40 parts of plant pectin, 20-30 parts of cellulose, 0.1-0.2 parts of curing agent, 1-2 parts of lubricant, 2-4 parts of silane coupling agent. The invention also discloses a preparation method of the imitation porcelain bottle. The invention has good impact strength.

Description

technical field [0001] The invention relates to the technical field of imitation porcelain materials, in particular to an imitation porcelain bottle and a preparation method thereof. Background technique [0002] Melamine formaldehyde resin is referred to as melamine resin, also known as melamine formaldehyde resin or melamine resin. It is an important triazine ring compound. Melamine resin has excellent water resistance, aging resistance, flame retardant, heat resistance, chemical resistance and insulation properties, and can be used in the manufacture of molding compounds (such as: daily tableware, imitation porcelain products and electrical appliances), wood-based panels (such as: plywood, Laminate floors and laminates) and foam, etc. However, melamine formaldehyde resin has poor toughness and is easily broken under stress, so it needs to be improved. SUMMARY OF THE INVENTION [0003] Based on the technical problems existing in the background art, the present inventio...
