Abstract

The invention discloses a polyurethane waxy release agent, which is characterized by comprising the following ingredients by weight: 20% of a demoulding wax, 10-20% of paraffin, 5-10% of microcrystalline wax, 0.5-1% of a foam stabilizer and 49-64.5% of a solvent. The invention has the beneficial effects that (1) good demoulding effect; (2) no pollution or corrosivity to mould surface; (3) repetitious usage for one time coating; and (4) especially suitable for demoulding of polyurethane high resilience foam.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a polyurethane (PU) wax release agent and its application, which is used in the production process of PU high-resilience foam products after pouring and molding to give most polyurethanes good mold release Effect, and concentrated application in the auto parts production industry. Background technique [0002] At present, the release agent (also called release agent) is an operation aid in the production process of polyurethane products. Its function is to prevent the polyurethane products from sticking to the mold after casting in the mold, causing the products to tear and damage, resulting in the failure of production. caused losses. After using the release agent, the product can be taken out of the mold smoothly, ensuring that it is in good condition, effectively improving labor productivity, reducing the loss of waste products, and improving economic benefits.
