Resin brick and release method for resin brick pressing

Abstract

The invention discloses a mold release method for resin brick pressing, which comprises the following steps: S1, mixing the components of a resin brick, and pressing in a mold; s2, preparing a release agent, coating the contact part of the resin brick and the mold with the release agent, and demolding; the resin brick comprises the following components in percentage by mass: 3.6-3.8% of epoxy resin, 1.4-1.6% of a curing agent, 7-8% of a brick powder additive and the balance of sand, wherein the total percentage of the components is 100%; the release agent is prepared from the following components in parts by mass: 0.8 to 1.2 parts of a surfactant and 2.8 to 3.2 parts of water. According to the mold release method for resin brick pressing, adhesion of the resin bricks on the surface of the mold can be reduced, the surface layer strength of the resin bricks is not affected, operation is easy, cost is reduced, and the safety performance and the environment-friendly performance are improved.

Description

A kind of resin brick and the mold release method of resin brick pressing technical field The present invention relates to resin application field, particularly a kind of resin brick and the mold release method of resin brick pressing. Background technique [0002] In the process of using resin concrete to press concrete products, such as resin bricks, it is necessary to solve the problem of demoulding. Currently Industrial alcohol or organic solvent is generally used to spray on the brick-making formwork to achieve the demoulding effect, but alcohol has potential safety hazards and is not safe. Organic release agents also have potential safety hazards and environmental pollution problems, and the use of the above methods will even affect the performance of resin permeable bricks. Surface layer strength, and high cost. Urgently need a kind of can reduce the adhesion of resin brick on mould surface, does not affect the surface layer strength of resin brick, easy to ope...

Problems solved by technology

At present, industrial alcohol or organic solvents are widely used to spray on the brick formwork to achieve the demoulding effect, but alcohol has potential safety hazards and is not safe, and organic release agents also have potential safety hazards and environmental pollution problems. Using the above method may even affect the water permeability of the resin. Brick surface strength, and the cost is higher
