Abstract
A kind of precast beam concrete surface optical brightener, be made up of methoxy poly (ethylene glycol) allyl capped polyethers (hereinafter referred to as polyethers), diethylene glycol monoacrylate, vinylformic acid, vinyl phosphonate, Thiovanic acid, ammonium persulphate, sodium hydroxide, its beneficial effect is: production technique is simple; Production quality control is easy; Be added in concrete and can increase precast beam surface brightness.
Description
Technical field
The present invention relates to a kind of concrete additive, be specifically related to a kind of additive that can increase precast beam concrete surface luminance brightness.
Background technology
At present, in railway and highway engineering, the surface of concrete prefabricated beam can form bubble, honeycomb and scale phenomenon, and this both have impact on the external sight of beam, have impact on again beam weight.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provides a kind of precast beam concrete surface optical brightener solving the brightless problem in beam surface.
For achieving the above object, the technical solution used in the present invention is: a kind of precast beam concrete surface optical brightener, by methoxy poly (ethylene glycol) allyl capped polyethers (hereinafter referred to as polyethers), diethylene glycol monoacrylate, vinylformic acid, vinyl phosphonate, Thiovanic acid, ammonium persulphate, sodium hydroxide forms, it is characterized in that: the weight percent preparing material therefor composition is: polyethers 78% ~ 88%, diethylene glycol monoacrylate 1.5% ~ 2.5%, vinylformic acid 3% ~ 5%, vinyl phosphonate 3% ~ 7%, Thiovanic acid 0.4% ~ 0.8%, ammonium persulphate 1% ~ 2%, sodium hydroxide 3% ~ 5%.
The invention has the beneficial effects as follows: production technique is simple; Production quality control is easy; Be added in concrete and can increase precast beam surface brightness.
