Industry is extended to the industries such as municipal administration, environmental protection, electric power, harbour comprehensively.
The spies such as epoxy resin has that adhesion strength is high, can solidify in room temperature, high mechanical properties and corrosion resistance and good
Point, is therefore widely used in the multiple fields such as electronics, machinery, building as binding agent, coating, grouting material etc..Asphalt mixtures modified by epoxy resin
Lipid grouting material is current using the chemical classes grouting material more larger than wide, amount ratio.Such material has shock resistance
Good toughness, can absorb vibrational energy, thus is widely used in the grouting of electronics material equipment Foundations and reinforcing.But asphalt mixtures modified by epoxy resin
Solidification under low-temperature construction environment for the fat is slow, has had a strong impact on efficiency of construction, and then limits under low-temperature construction environment
The application of epoxiess chemical grouting material.
Because epoxy resin oneself viscosity ratio is larger, the binding agent as grouting material generally needed to be added activity dilution
Agent.Furfural-acetone system dilution effect is good, is the diluent more commonly used.Chinese patent literature 87105255.5,
01107590.2 and 201010598220.0 etc. discloses a series of asphalt mixtures modified by epoxy resin with furfural-acetone system as reactive diluent
Lipid grouting material, these materials have excellent mechanical property, but furfural-acetone class reactive diluent high volatility, poison
Property is larger, using being increasingly subject to strict restriction.Chinese patent literature cn102070873a employs (+)-2,3-Epoxy-1-propanol ethers chemical combination
Thing have developed a kind of epoxide resin grouting material of environmental protection flexible as diluent, this material small toxicity, excellent in mechanical performance, material
Material pliability is good, but (+)-2,3-Epoxy-1-propanol ethers compound is expensive, substantially increases the use cost of epoxy grouting material.In
State patent documentation cn102898075a disclose a kind of high-strength consolidate epoxy resin grouting material soon, this material is in laboratory environment
Lower intensity is higher, development fast and the adhesion strength height of base material, good endurance, the features such as prepare simple, but be room temperature
Can, the effect under low-temperature construction environment is unsatisfactory.
Since entering 21st century, China's steel industry fast development, create substantial amounts of discarded slag, cause to environment
Huge pressure, and still increased with more than one hundred million every year tons of speed.How effectively to solve the comprehensive utilization of garbage, reduce ring
Border pressure is so as to turning waste into wealth is recycling economy and sustainable development important topic.
In sum, it is developed for that epoxy grouting material under low-temperature construction environment is now particularly important, this material can fill
Divide and absorb vibrational energy, improve the impact resistance of grout blanket；Meanwhile, can widely apply industrial residue again, for example steel-making slag powder and
Granule, turns waste into wealth, and can be widely applied to the infrastructure grouting of the industries such as oil, chemical industry, papermaking, electronics and reinforcement adds
Gu.
