Embodiment Construction

[0015] The present invention will be further described below in conjunction with embodiment.

[0016] The present embodiment equipment only needs a reaction kettle and a small atmospheric pressure boiler. According to the formula and process, the release agent that can be diluted with water can be produced.

[0017] The emulsified paraffin release agent of the present embodiment is prepared from the following raw material ratio (by weight):

[0018] 10 parts of paraffin, 2 parts of stearic acid, 1 part of borax, 0.5 part of hydroxypropyl methylcellulose (HPMC), 0.6 part of Pingpingjia, 0.1 part of triethanolamine, 85.8 parts of water, appropriate amount of defoamer; Pingpingjia refers to Fatty alcohol polyoxyethylene ether. Take the raw materials according to the ratio, and then make it according to the following steps:

[0019] a. Heating paraffin and stearic acid into a hot solution at 80-90°C, keeping it warm for later use;

[0020] b. Add water to the reaction kettle, ...

Abstract

The invention discloses an emulsified paraffin release agent and a manufacturing method thereof. The emulsified paraffin release agent comprises the following raw materials in portions by weight:10 portions of paraffin, 2 portions of stearic acid, 1 portion of borax, 0.5 portion of HPMC, 0.6 portion of peregal, 0.1 portion of triethanolamine, 85.8 portions of water and adequate defoamer. The manufacturing method comprises the following steps: heating to dissolve the paraffin and the stearic acid at 80-90 DEG C, and keeping the temperature for later use; adding water into a reaction kettle, heating the borax to 40-50 DEG C under continuous stirring condition, slowly adding the HPMC while quickly stirring, heating to 80-85 DEG C, pouring the transparent emulsifying agent peregal solution, and slowly pouring the paraffin and stearic acid which are molten by heating into the transparent solution while stirring quickly; and finally, adding the triethanolamine, and stirring for several minutes. The invention can replace expensive machine oil, can be freely diluted with water, and can be sprayed or coated. The invention has the advantages of good film release performance and wide application range, and can enable the surface to be smooth and beautiful.

Description

technical field [0001] The invention relates to the technical field of building material production, in particular to an emulsified paraffin release agent and a production method thereof. Background technique [0002] In recent years, some fine cement concrete prefabricated parts such as colored bricks, colored tiles, curbs, manhole covers, Roman columns, and artificial marble have emerged continuously. When these products are made, plastic molds are generally required, and a release agent is applied during use. Its main features: easy demoulding, smooth surface, without leaving any traces; secondly, no secondary modification, one-time molding. At present, the release agent of this kind of fine mold mainly uses engine oil, and its disadvantages are: first, the price is high, and second, the surface is oily, which is very unfavorable for popularization and use. Contents of the invention [0003] In view of this, the purpose of the present invention is to overcome the defe...
