preparation example Construction

[0024] The preparation method of thermosetting resin release agent includes the following steps:

[0025] (1) Place the artificial stone waste in a crushing device and crush it to 600-2000 mesh to obtain artificial stone powder, then add deionized water and surfactants and place it in a disperser and stir at high speed for 10 minutes to obtain an artificial stone powder dispersion;

[0026] (2) Configure the active material solution, and add inorganic porous powder to the active material solution under low-speed stirring, add surfactant after drying, stir for 2h, then add 5% liquid paraffin, stir for 5h, add surfactant, Stir at high speed for 10 minutes to load the active material on the hollow structure of the inorganic porous powder surface;

[0027] (3) Add artificial stone powder dispersion and film-forming resin to the solution obtained in step (2) under low-speed stirring, and stir at high-speed for 10 minutes;

[0028] (4) Slowly add nano-scale silica to the mixture obtained in...

Abstract

The invention discloses a thermosetting resin mold release agent. The thermosetting resin mold release agent comprises the following components, 20-80 parts of artificial stone material wastes, 10-80parts of porous inorganic powder bodies, 0.5-8 parts of active materials, 0.5-10 parts of surface active agent, 1-10 parts of nanometer silica, 2-10 parts of water-borne silicone oil, 40-90 parts of film-forming resin and 0.5-3 parts of flatting agent. Compared with the prior art, the thermosetting resin mold release agent has the beneficial effects that wastes in an artificial stone plate factoryis subjected to regeneration comprehensive utilization, so that secondary pollution is avoided; the prepared mold release agent is used for mold release of thermosetting resin, and mold release effect is good; and pernicious gas released in a solidification process of the thermosetting resin can be adsorbed and decomposed. The preparation method is energy-saving, environment-friendly, innoxious and harmless, and can be industrialized.

Description

Technical field [0001] The invention relates to the field of mold release agents for abrasive tools, in particular to a thermosetting resin mold release agent and a preparation method thereof. Background technique [0002] Release agent is an interface coating used on the surface of two objects that are easy to adhere to each other. It can make the surface of the object easy to peel off, smooth and clean. Mold release agents are used in various molding operations such as glass fiber reinforced plastics, metal die-casting, polyurethane foams and elastomers, injection molded thermoplastics, vacuum foamed sheets and extruded profiles. The release agent has chemical resistance, heat resistance and stress properties, and is not easy to decompose or wear. The release agent adheres to the mold and does not transfer to the processed part so as not to interfere with painting or other secondary reprocessing operations. [0003] In the current market, in pursuit of more superior performanc...
