Embodiment Construction

[0028] The case will be described in further detail below in conjunction with specific embodiments and tests.

[0029] The present invention relates to a release agent composition, the component formula of which is as follows:

[0030] BN release agent 10-150g / L

[0031] Polyvinylpyrrolidone 1-20g / L

[0032] Among them, the solvent is absolute ethanol.

[0033] Preferably, the amount of BN mold release agent (boron nitride mold release agent) is 56-80 g / L; polyvinylpyrrolidone (PVP) is used as a dispersant, and its preferred amount is 5-8 g / L.

[0034] The first preferred embodiment is a release agent composition, the component formula of which is as follows: BN release agent dosage is 80g / L, polyvinylpyrrolidone (PVP) dosage is 8g / L, wherein the solvent is absolute ethanol.

[0035] The second preferred embodiment is a release agent composition, the component formula of which is as follows: BN release agent dosage is 72g / L, polyvinylpyrrolidone (PVP) dosage is 7g / L, and the solvent is ab...

Abstract

The invention discloses a release agent composition. The release agent composition is prepared from a BN release agent with the concentration of 10-150 g / L and polyvinylpyrrolidone with the concentration of 1-20 g / L, wherein absolute ethyl alcohol is adopted as solvent. According to the release agent composition, the BN release agent with the certain concentration is added into the absolute ethyl alcohol solvent and cooperates with polyvinylpyrrolidone with the appropriate concentration; the obtained release agent composition is good in uniform dispersion effect, not prone to be deposited at the bottom of a vessel during usage and very beneficial for coating of the release agent and a mold (a graphite pressure head), the release agent and the mold are combined firmly, the release agent is not prone to be erased during usage, the release agent is extremely good in stability and release effect, and the production requirements are met.

Description

Technical field [0001] The invention relates to a release agent composition, which is mainly used for various molds such as graphite. Background technique [0002] The release agent is a functional substance between the mold and the finished product. It is used as an interface coating on the surface of two objects that are easy to adhere to each other. It can make the surface of the object easy to detach, smooth and clean. In use, the release agent is prone to uneven dispersion and easy to deposit. More importantly, there is a problem of weak bonding between the release agent and the mold, which is easy to be wiped off, which affects the normal process operation and the finished product effect, and cannot meet the production needs. Summary of the invention [0003] The purpose of the present invention is to provide a release agent composition, which overcomes the problems in the prior art that the release agent is unevenly dispersed, easily deposited, not firmly bonded, and easily...
