Abstract

The invention discloses a concrete release agent prepared from animal fat and a preparation method thereof. The concrete release agent is prepared from the following raw materials in parts by weight: 40-45 parts of modified animal fat, 25-30 parts of SDBS (sodium dodecyl benzene sulfonate), 6-8 parts of silica sol, 0.5-2.0 parts of a potassium chloride liquid, 2-4 parts of an acrylic emulsion, 0.3-0.4 part of dimethylformamide, 5-6 parts of water glass, 1.5-2.0 parts of tartaric acid, 0.4-0.5 part of molecular sieve slurry, 0.2-0.4 part of sodium borosilicate, 1.5-2.0 parts of butyl oleate, 4-5 parts of vinyl triethoxysilane and 220-250 parts of deionized water. The concrete release agent disclosed by the invention is simple in composition and economic and environment-friendly in adopted raw materials and can be used for effectively improving releasing form between the concrete and a mould in a production processing process. Animal fat is taken as a main material, thus having good lubricating property. The concrete release agent disclosed by the invention is good in releasing effect, low in cost, convenient to use and good in stability.

Description

A kind of concrete parting agent made with animal grease

Technical field

The invention provides a kind of concrete parting agent, particularly a kind of concrete parting agent made with animal grease.

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 animal grease.

The present invention adopts following technical scheme to achieve these goals:

With the concrete parting agent that animal grease is made, the weight part of its constitutive material is: modified animal grease 40-45, Sodium dodecylbenzene sulfonate 25-30, silicon sol 6-8, Klorvess Liquid 0.5-1.0, ACRYLIC EMULSION 2-4, dimethyl formamide 0.3-0.4, water glass 5-6, tartrate 1.5-2.0, molecular sieve pulp 0.4-0.5, borsyl 0.2-0.4, butyl oleate 1.8, vinyltriethoxysilane 4-5 and deionized water 220-250.

With the concrete parting agent that animal grease is made, the weight part of its constitutive material is: modified animal grease 42, Sodium dodecylbenzene sulfonate 28, silicon sol 7, Klorvess Liquid 0.8, ACRYLIC EMULSION 3, dimethyl formamide 0.3, water glass 5.5, tartrate 1.8, molecular sieve pulp 0.5, borsyl 0.3, butyl oleate 1.5-2.0, vinyltriethoxysilane 4.5 and deionized water 230.

The preparation of described modified animal grease: first animal grease is heated to 50-60 DEG C; Then the 3.5-4.0% ferrous sulfate of animal grease 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 animal grease 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.

Beneficial effect of the present invention:

The present invention forms simply, raw material economics environmental protection; Employing animal grease is major ingredient, and lubricity is good, and what adopt the releasing agent that obtains of the present invention can effectively improve in the concrete production course of processing and between mould is release, and concrete parting agent stripping result of the present invention is good, helps cheap, easy to use, good stability.

Embodiment

Embodiment 1: the concrete parting agent made with animal grease, the weight part (kg) of its constitutive material is: modified animal grease 42, Sodium dodecylbenzene sulfonate 28, silicon sol 7, Klorvess Liquid 0.8, ACRYLIC EMULSION 3, dimethyl formamide 0.3, water glass 5.5, tartrate 1.8, molecular sieve pulp 0.5, borsyl 0.3, butyl oleate 1.8, vinyltriethoxysilane 4.5 and deionized water 230.

The preparation of described modified animal grease: first animal grease is heated to 55 DEG C; Then 3.8% ferrous sulfate of animal grease quality, 8% carbon fiber, 12% bamboo fibers is added wherein; Be uniformly mixed and place 2-3 hour, and then add the potassium humate powder of animal grease 4.5%, be warming up to uniform stirring 1-2 hour under the condition of 85 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 35 minutes, centrifugation obtains filtrate.

Above-mentioned obtained concrete parting agent solid content≤3.5%; To steel plate without any corrosion harmfulness, dry film time 50-55min; Concrete surface is smooth, and adhesive capacity is 4.0g/m ², meet the service requirements of concrete parting agent.
