Embodiment Construction

[0017] The preparation process of the release agent of the present invention can be completed at low temperature, and only one reaction kettle is needed for production. First prepare raw materials (weight ratio) according to following proportioning: sodium hydroxide, 2; Rosin, 8; Ethanol, 6; Emulsifier, 7; Stearic acid, 12; Wherein said sodium hydroxide uses the solid caustic soda of medium sheet or granular; Rosin is III grade product; Ethanol is the 95% ethanol product of purity; Its mixture; stearic acid, that is, octadecanoic acid is a granular solid; engine oil is 50 # Engine oil or waste engine oil; the stabilizer is hydroxypropyl methylcellulose, which is a high molecular polymer. After the raw materials are prepared, proceed as follows: (1) Dissolve the solid caustic soda, add ethanol to the lye, stir slowly, and heat to 50-55 degrees Celsius; (2) Grind the rosin and slowly add the above solution During the process, the feeding time is controlled to be 35 minutes; af...

Abstract

The invention discloses an emulsified machine oil release agent and a preparation method thereof. The release agent is prepared from the following raw materials in percentage by weight: 2 percent of sodium hydroxide, 8 percent of rosin, 6 percent of ethanol, 7 percent of emulsifying agent, 12 percent of stearic acid, 55 percent of machine oil, 9.9 percent of water and a proper amount of stabling agent, wherein the emulsifying agent is one or a mixture of two of an OP emulsifying agent, a Span emulsifying agent and a Tween emulsifying agent; and after the raw materials are prepared, the release agent is prepared by steps. The release agent has strong water solubility, can be diluted freely by water, has low cost, solves the problem that the release agent in the prior art has oil stain residue and high cost, saves cost for construction technology and ensures quality safety of building members.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an emulsified engine oil release agent and a manufacturing method thereof. Background technique [0002] At present, most of the release agents used for building formwork and concrete prefabricated parts are oil-based. Although this kind of material saves trouble and is convenient, it will cause oil residue on the concrete base surface that needs to be faced or docked, and will eventually lead to weak bonding of the facing or butt-joined concrete components. In addition, as the price of oil continues to rise, the production cost of this type of release agent is also increasing, so it is bound to increase the construction cost. Contents of the invention [0003] In view of this, the purpose of the present invention is to provide a kind of emulsified engine oil release agent, this release agent is water-soluble, can be arbitrarily diluted with water, and cost is low, ...
