Abstract

The invention discloses a polyurethane water-based release agent. The polyurethane water-based release agent is characterized by comprising the following raw materials in parts by weight: 10-15 parts of emulsifying wax liquid, 15-20 parts of methylsilicone oil emulsion, 5-8 parts of modified silicon oil emulsion, 50-55 parts of de-ionized water, 4.5-6 parts of an emulsifying agent, 0.5-1 part of additive, and 0.3-0.5 part of preservative. The polyurethane water-based release agent has the following beneficial effects: the water-based release agent is mainly applied to the release of polyurethane products in the production process after the casting, and gains excellent release agent on the molding of most polyurethane products. The polyurethane water-based release agent uses water as a dispersion phase; a formed water soluble object has a function of demolding polyurethane foam, has the biodegradability, has no generation of such harmful substances as VOC, and is strong in environmental protection; and moreover, the water serves as diluent, so that the polyurethane water-based release agent has such advantages as no pollution, easy obtaining and low cost.

Description

technical field [0001] The invention relates to the field of mold manufacturing, in particular to a polyurethane water-based release agent. Background technique [0002] The mold release agent (mold discharging agent) is a functional substance between the mold and the finished product. Mold release agents are chemically resistant and do not dissolve when in contact with the chemical composition of different resins (especially styrene and amines). The release agent also has heat and stress resistance, and is not easy to decompose or wear; the release agent adheres to the mold and does not transfer to the workpiece to be processed, and does not hinder painting or other secondary processing operations. Due to the rapid development of injection molding, extrusion, calendering, molding, lamination and other processes, the amount of release agent has also increased significantly. Most of the existing general release agents are not environmentally friendly, and the efficiency of ...
