Description
Technical field
The present invention relates to a kind of preparation methods of acrylic emulsion.More particularly to a kind of monomer modified propylene yogurt of Organic fluoride
The preparation method of the preparation method aqua of liquid.
Technical background
With the development of modern high-grade highway, cement concrete becomes high grade pavement as bituminous concrete
Primary building material.Cement concrete pavement has intensity high, and stability is good, and durability is good, and cost is appropriate, maintenance cost
It is small, many advantages, such as driving at night is visual good.And current present situation is that often 3-5 years just for newly-built cement concrete road
Appearance is resolved plate, hollow etc. and is seriously destroyed, damaged concrete road surface cause every year directly or indirectly economic loss up to 24.01 hundred million
Member.Because the shortcomings that cement concrete pavement is that relatively low brittleness big, flexible low, tension, flexural strength, easy cunning, noise be big, drying shrinkage
Amount is big, and resistance to chemical attack is not high.Gradually deep with modernization construction with the development of science and technology, people are seeking always
The approach improved to portland cement concrete is looked for, such as improves the property of cement, addition fibrous material, add additive
Deng.Improvement to concrete basic mechanical characteristic, particularly reduce concrete rigidity, improve toughness, reduce backfin than arrange
One of apply is exactly that cement road concrete is modified using high molecular polymer.
Li Yang etc. is by the way that with 12-16 mesh rubber particle, with volume volume 20% generation sand, the rubber particle concrete of preparation resists
Compressive Strength reaches more than C35, and flexural strength reaches more than 4.5MPa, meets road concrete intensity requirement.Liang Naixing etc. uses fourth
The pavement performance of the emulsion modified concrete of benzene go deep into the analysis of system, and concrete is after styrene-butadiene emulsion is mixed, the anti-folding of 7 days
Intensity improves 22% relative to common concrete, and anti-folding elasticity modulus reduces about 24%, and the flexural strength of 28 days improves
38%, anti-folding elasticity modulus reduces about 21%, and the flexural strength of 90 days improves 27%, and anti-folding elasticity modulus reduces about
19%.The incorporation of styrene-butadiene emulsion significantly improves the flexural strength of concrete, elastic feel quantity reduces, it is flexible increase, drying shrinkage and
Wearability is improved.Yao Hongyun etc. through a large number of experiments mixes ordinary cement with theory analysis, discovery Carboxy lotion
Solidifying soil has water-reduction, and contract with dry rate reduces, and rigidity reduces.Li Fang etc. is found through experiments that Carboxy lotion to improving cement bonded sand
Slurry is bonded with obvious action, and backfin ratio can be greatly lowered, and obtains the workability in optimization Polymer-Modified Mortar,
It can not consider the conclusion of the size of the ratio of mud.Li Zhendong etc. has studied acid cation polychloroprene latex and cement mortar is changed
Property, the flexural strength 70---50% of material can be improved by doing wet-cured method, reaches 10MPa.The incorporation of polychloroprene latex
The impermeability of material can be improved, reduce water absorption rate, increase adhesion strength.Xu Xianmin etc. describes external styrene-fourth two
The performance and construction method of the latex modified concrete of alkene, can be long-term widely using a large amount of finishing coats on road and bridge
Performance and economic benefit are confirmed by case study and live report.Zhang Zhenxiu describes styrene butadiene latex modified concrete, from
It can meet easy mix, good workability, self preferable maintenance, good cohesion, hyposmosis, reduce elasticity modulus etc.
Feature has made deep explanation.Zhang Jiantao carries out Carboxy modified cement-concrete microstructure by various means of testing
Research, discloses improvement of the Carboxy lotion to cement concrete micro-property.Wang Xiaochen etc. uses polyacrylate emulsion pair
Concrete is modified.Modified concrete crushing strength improves a lot.
From reading up the literature it is found that at present in the domestic research to polymer emulsion modified cement road concrete, used is poly-
Conjunction object lotion is not mentioned to be modified with organic fluorine monomer.And the lotion that organic fluorine monomer and polymerizable acrylic monomer are formed, surface
Tension is low, water resistance is good, and in road concrete, concrete shrinkage amount is small, and resist chemical is good, High anti bending strength, resists
Oozing property is good, so that the service life of concrete road surface extends.
