Abstract
The invention discloses a concrete release agent prepared from mineral oil and a preparation method of the concrete release agent. The concrete release agent is prepared from the following raw materials in parts by weight: 40-45 parts of modified mineral oil, 25-30 parts of sodium laurate, 0.4-0.5 part of trilaurin, 2-4 parts of triethanolamine, 0.6-0.8 part of polyvinylpyrrolidone, 2-4 parts of magnesium sulfate, 1.5-2.0 parts of sodium hexametaphoshpate, 3-5 parts of cyclodextrin, 0.4-0.5 part of glucan, 5-10 parts of a silane coupling agent KH-500 and 250-280 parts of deionized water. With modified mineral oil as a main material, the chemical property is neutral; the prepared release agent has no peculiar smell and is good in demolding effect, free of corrosion to a template, non-toxic and odorless; the mold is low in concrete adhesion; and in addition, the assistants such as a coupling reagent, an emulsifier and a stabilizer are added, so that the prepared release agent has the characteristic of oil-water compatibility, can be widely applied to demolding of concrete parts, and is also suitable for various templates.
Description
Technical field
The invention provides a kind of concrete parting agent, particularly a kind of concrete parting agent made with mineral oil and preparation method thereof.
Background technology
Concrete parting agent is also known as concrete isolation agent or demoulding lubricant; Be one be applied to template inwall rise lubrication and buffer action, make concrete can depart from template smoothly when form removal, keep the intact material of concrete shape, traditional release materials adds diesel oil with machine oil or used oil, find in the engineering constructions such as long-term water conservancy and hydropower, highway, railway, use used oil brushing template, concrete surface is produced and pollutes, pollution in various degree is also caused to environment simultaneously; But existing releasing agent exist stripping result not good, be difficult to remove in template, and ineffective to template maintenance, operating efficiency etc. is affected also increases construction cost.
Summary of the invention
The object of the present invention is to provide a kind of concrete parting agent made with mineral oil and preparation method thereof.
The present invention adopts following technical scheme to achieve these goals:
With the concrete parting agent that mineral oil is made, the weight part of its constitutive material is: modified mineral matter oil 40-45, sodium laurate 25-30, triglycerin fatty acid ester 0.4-0.5, trolamine 2-4, polyvinylpyrrolidone 0.6-0.8, magnesium sulfate 2-4, sodium hexametaphosphate 1.5-2.0, cyclodextrin 3-5, dextran 0.4-0.5, silane resin acceptor kh-550 5-10 and deionized water 250-280.
With the concrete parting agent that mineral oil is made, the weight part of its constitutive material is: modified mineral matter oil 42, sodium laurate 28, triglycerin fatty acid ester 0.5, trolamine 3, polyvinylpyrrolidone 0.7, magnesium sulfate 3, sodium hexametaphosphate 1.8, cyclodextrin 4, dextran 0.5, silane resin acceptor kh-550 8 and deionized water 250.
The preparation method of the concrete parting agent made with mineral oil, comprises following content:
(1) preparation of modified mineral oil: first mineral oil is heated to 50-60 DEG C; Then the 3.5-4.0% ferrous sulfate of mineral oil quality, 8-10% carbon fiber, 10-15% bamboo fibers is added wherein; Be uniformly mixed and place 2-3 hour, and then add the potassium humate powder of mineral oil 4-5%, be warming up to uniform stirring 1-2 hour under the condition of 80-90 DEG C, naturally cool to room temperature, regulator solution pH value is to 2-3; Again with deionized water in mass ratio 1:5 mix, stir 30-40 minute, centrifugation obtains filtrate;
(2) take by weight modified mineral oil and deionized water pour in reactor stand-by; Cyclodextrin, dextran is added after being heated to 85-100 DEG C; Stir and be incubated 20-30min; And then pour other residue constitutive material into, be warming up to 150-180 DEG C, continue to stir 3-5 minute; Finally cooling leaves standstill homogenizing.
Beneficial effect of the present invention:
The present invention is oily for major ingredient with modified mineral, learn stable in properties in neutral, free from extraneous odour, the releasing agent stripping result made is good, not Erodent Algorithm, nontoxic odorless, the sticky amount of mould concrete is few, in addition, the present invention adds the auxiliary agents such as coupling agent, emulsifying agent, stablizer, and the releasing agent of preparation has the compatible feature of profit, the demoulding of concrete article can be widely used in, also be applicable to various template.
