Abstract
The demoulding is with the composition of raw materials and the manufacture method of releasing agent when the invention discloses a kind of concreting.The releasing agent made with the present invention can use in the process of building repeatedly, the sort ofly do not build a concrete and will on template, brush one deck mould wash and do not resemble usually, its stripping result is good, and the concrete surface that the demoulding goes out is smooth smooth, and the manufacturing cost of releasing agent is also very low.
Description
The releasing agent of template surface brushing when the invention belongs to the architectural engineering placing concrete, its function are that concrete and template are isolated.
Have interleaving agent both at home and abroad now, the releasing agent great majority are pure oils, emulsification oils paraffin wax class, ester fat acids etc., all there is following defective in these releasing agents: first only is disposable use, promptly all will be before each casting at template surface brushing one deck releasing agent, second demoulding usefulness is undesirable, bonding phenomenon still takes place frequently in casting cycle, and the cast concrete surface quality is relatively poor.
In China's architectural engineering, the concrete product occupies very big proportion at present, improves the surface quality of concrete product, reduces manufacturing cost, is still a big problem in building trade.
The present invention is intended to solve the above-mentioned two problems that existing releasing agent exists, and develops the releasing agent that a kind of energy is reusable and demoulding usefulness is high.
The solution that the present invention adopts is: select that bonding force is strong, shrinkage is little for use, chemical stability, hear resistance, water-resistance and mechanical strength height, but the epoxy resin of outdoor weathe resistance difference, compact structure, chemical stability, shielding buffer action, rotproofness, outdoor weathe resistance is all got well but rigidity is big, hard and crisp phenolic resins reaches flexibilizer, curing agent, filler, pigment, diluent.It is compound by a certain percentage, utilize the mutual constraint between each component property, learn from other's strong points to offset one's weaknesses, form.
The present invention has two kinds of prescriptions, as following table:
The material name additive performance fills a prescription two
Epoxy resin 100 100
Phenolic resins 25 41
O-phthalic toughness reinforcing 12 15
Dibutyl phthalate
Ethylenediamine solidifies 6.2 6.2
Talcum powder fills 3 6.4
Ferric oxide red colorant 32/
Powdered carbon pigment/32.7
The alcohol dilution is an amount of
Each component can change in 2% scope.
The compound method of releasing agent: at first just stir, by ratio shown in the prescription (input of following raw material is in ratio shown in filling a prescription) with epoxy resin, flexibilizer, filler, pigment just stir under 40 ° of-50 ° of conditions, wet pigments is disperseed, secondly grind, the mixture of last process is ground to the fineness of 20-40M, be powerful the stirring at last, curing agent is added in the mixture behind the last process, and brute force is stirred and is trembled 20 minutes, adds phenolic resins again, diluent stirred 20 minutes.
Effect of the present invention is: made template with releasing agent of the present invention, can cast repeatedly over one hundred time, it waters the concrete surface that casts out, and is smooth smooth, because the releasing agent cost is not high, releasing agent can use repeatedly in casting cycle, so demoulding cost is very low.
Claims (2)
1, a kind of releasing agent is characterized in that being two kinds of composition of raw materials as shown in the table that each change of component scope is controlled in 2%.
