Description
Technical field
The present invention relates to mortar manufacturing technology field, in particular to a kind of epoxy-modified mortar system using silane coupling agent
Preparation Method.
Background technique
Epoxy resin mortar is to be equipped with a series of auxiliary agents such as promotor using epoxy resin as host agent, form one after mixing cured
The induration of kind of high-intensitive, high cohesive force with excellent impervious, freeze proof, salt tolerant, alkaline-resisting, weak acid resistant Corrosion Protection and is repaired
Mend reinforcement performance.Its organic moiety is the solidfied material generated after epoxy resin and curing agent reaction, and glue is served as in whole system
Tie material；Inorganic part is mainly inert filler, such as quartz sand, cement.Diluent can be added in order to optimize performance also, increase
Tough dose etc..This mortar has good workability, and intensity is high, impact resistance and wearability are good, cohesive force is strong and resistance to
Water and chemical solvent corrode.Just because of these features of epoxy resin mortar, therefore it is widely used in concrete structure repairing, adds
Gu, grouting, anchoring, the construction such as terrace.
Epoxy-plastic packaging material (EMC) and phenolic aldehyde plastic packaging material (PMC) belong to moulding compound material after molding, since it is with excellent
Good electric property, mechanical performance, heat resistance, chemical corrosion resistance, and various moulding process are adapted to, so being widely used
In electronics industry, electric motor of automobile, electric tool etc..Moulding compound is a kind of semidry method manufacture glass-fiber reinforced thermo-setting product
Intermediate materials are molded, by unsaturated polyester resin class, lower shrinkage/low-contour additive, initiator, inner pattern releasing agent applicable, mineral filler
Etc. paste is pre-mixed into, add thickener, colorant etc., the glass fibre with different length, in dedicated material kettle into
Row stirring, carries out thickening, ultimately forms the intermediary material of bulk, can be used for being molded and being molded.
With the development of industry, the dosage of plastic packaging material is continuously increased, and plastic packaging material class material waste quantity also sharply increases,
Belong to thermosetting resin base plastic packaging material is not degradable and recycling, traditional processing method is to bury and burn, but due to this
A little buried a century of waste material are stale-proof, and bury and to occupy a large amount of soil and polluted underground water, and burn the black smoke generated and toxic
Gas had not only polluted environment but also had been detrimental to health, and processing cost is higher, and treating capacity is limited, useless far from plastic packaging material class material is met
The requirement of gurry increasing number.
Epoxy resin mortar needs that there is certain mechanical property can just be put into use, mainly uses natural sand stone, cement
Deng being used as reinforcing material, but with the fast development of building trade, the demand of sandstone is increasing, and people provide natural sand stone
The exploitation of source transition utilizes, and causes natural sand resource more and more rare.Reinforcing material in plastic packaging material has using fine sand, be chopped fibre
Dimension, roving, high silica fiber, carbon fiber, asbestos fibre, nylon fiber, aramid fiber etc..So using certain means,
It is reasonable to efficiently use such waste using useless plastic packaging material substitution partial natural sands stone, pollution is reduced, can more be protected
Save natural sand stone resource.
Since broken useless plastic packaging material maintains the physico of certain (raw material of plastic packaging material) resin and reinforcing fiber
Property is learned, wherein a small amount of resin component still retains branched group.Therefore, part quartz sand, water are substituted with useless plastic packaging material particle
Mud, the reasonable mixing ratio for adjusting epoxy resin mortar may make epoxy resin and the closer combination of useless plastic packaging material, compared to
Virgin quartz sand, cement can reduce porosity, increase intensity as filler.
Silane coupling agent one kind has the low molecule organo-silicon compound of special construction, general formula RSiX3, R generation in formula
Table and polymer molecule have the active function groups of affinity or respond, such as oxygroup, sulfydryl, vinyl, epoxy group, amide
Base, aminopropyl etc.；X represents the alkoxy that can be hydrolyzed, such as halogen, alkoxy, acyloxy.Its group energy and silicon dioxide meter
The molecular action of the silanol groups in face or other inorganic filler surfaces forms covalent bond；In addition, coupling agent also contain it is a kind of other
A kind of different functional groups's (amino) are bonded with polymerizable molecular, and to obtain good interface cohesion, coupling agent is just played inorganic
It is mutually acted on as bridge interconnected between organic phase, silane coupling agent is improved in composite material by chemical bonds
Cementability between high polymer and inorganic filler, make its performance substantially improve mitigate composite material it is cooling when due to resin and fill out
The difference of percent thermal shrinkage between material and the interfacial stress generated, adjacent resin boundary surface is one flexible with processed inorganic matter
Property deformable phase, silane coupling agent reinforces infiltration of the liquid resin to useless plastic packaging material, increases the toughness of composite material.
There has been no useless plastic packaging material class material is added to the way deployed in epoxy resin mortar for the country.
Useless plastic packaging material density is smaller, needs to be modulated to suitable ratio with epoxy glue solution, product just may make to reach effective
Intensity.
Adhesive strength between useless plastic packaging material surface and cement slurry is lower, so using epoxy resin as gelling material
Material.Useless plastic packaging material particle makes since there are one layer of organic components on its surface compared to the material of cement base relative to natural sand
Solidified with epoxy resin, product effect is more preferable.Plastic packaging material aggregate intensity is slightly below natural sand, but the mean intensity of product can
Reach 75Mpa or more and flexural capacity has the raising of 5%-10% or so because of the presence of organic component.
It is pre-processed using silane coupling agent, product strength index can obtain 10% or so raising.
Summary of the invention
