Abstract
The invention relates to a vinyl ester resin polymer cement mortar composition, which mainly comprises: the vinyl ester resin polymer cement mortar has the advantages of high strength, good toughness, excellent impermeability, corrosion resistance, curing performance and other performances, and low cost.
Description
Technical Field
The invention relates to polymer cement mortar, in particular to vinyl ester resin polymer cement mortar.
Background
The polymer emulsion is added into cement mortar at the end of the last century, the water-based polymer emulsion provides water required by cement hydration, and meanwhile, after the water is reacted, the remained polymer can form a net-shaped film in the cement mortar to change the flocculation structure of a cement casting.
A polyester cement is developed in the United states in the 80 s, is used for quick repair or pavement paving of cement pavements, and can bear 43MPa of strong pressure after 3-24 hours, so that the polyester cement mortar has the characteristics of higher compressive strength, high fracture energy, low brittleness and the like compared with polymer emulsion modified cement mortar, and the curing speed is high.
Compared with common polymer emulsion modified mortar, the epoxy resin modified cement mortar has new change, because the epoxy resin or the emulsion type epoxy resin can form a cross-linked reticular structure in the cement, and meanwhile, the secondary hydroxyl of the epoxy resin has strong bonding capability to inorganic fillers and cement parts, the strength, toughness, permeability resistance and corrosion resistance of the epoxy resin cement mortar are improved to a greater extent.
However, the polymer emulsion reinforced cement mortar has obvious disadvantages, and the polymer emulsion used in the cement mortar is usually styrene-butadiene latex, carboxylic styrene-butadiene, neoprene latex, acrylate copolymer emulsion, etc., and the emulsion is added into the cement mortar to be solidified into thermoplastic resin and not crosslinked into a three-dimensional network structure, so that although the toughness of a casting is increased, the rigidity and the strength of the casting are obviously reduced. At the same time, the uncrosslinked resin is also less resistant to chemical attack and heat.
The unsaturated polyester in the unsaturated polyester cement mortar has relatively weak bonding strength to inorganic matters, has a not ideal bonding effect to plain mortar casting pieces, can be well repaired only by carrying out surface treatment on the plain mortar casting pieces, has relatively large curing shrinkage rate and is easy to generate micro cracks on the casting pieces.
The epoxy resin mortar is relatively slow in curing, so that the cast-in-place casting cannot be rapidly produced, and the concrete casting cannot be repaired in an operating state.
Therefore, the development of a low-cost cement mortar with high strength, good toughness, excellent impermeability, corrosion resistance, curing performance and other properties is urgently needed.
Disclosure of Invention
In view of the above, there is a need for a vinyl ester polymer cement mortar that can combine both unsaturated polyester resins and epoxy resins.
A vinyl ester resin polymer cement mortar composition comprising:
100 parts by weight of a liquid vinyl ester resin;
1-1.5 parts by weight of a curing agent;
0.2 to 0.8 part by weight of an accelerator;
1-2 parts by weight of a coupling agent;
0-1 part by weight of liquid paraffin;
60-240 parts by weight of portland cement;
300-1200 parts by weight of quartz sand;
18-72 parts by weight of water;
25-60 parts by weight of montmorillonite;
0 to 20 parts by weight of fumed silica/precipitated silica.
Preferably, the liquid vinyl ester resin contains a vinyl-containing reactive diluent, which includes, but is not limited to, one or a mixture of: 8 to 40 weight percent of styrene and 8 to 40 weight percent of alpha-methyl styrene.
Preferably, the liquid vinyl ester resin contains a vinyl-containing reactive diluent, either a mixture of 8-40% by weight styrene and 8-30% by weight diallyl phthalate of the liquid vinyl ester resin, or a mixture of 8-40% by weight alpha-methylstyrene and 8-30% by weight diallyl phthalate of the liquid vinyl ester resin.
Preferably, the liquid vinyl ester resin contains 60-80% of epoxy vinyl ester resin or the liquid vinyl ester resin contains 30-40% of epoxy vinyl ester resin and 30-40% of o-phenyl unsaturated polyester.
Preferably, the mesh number of the quartz sand is 10-20 meshes.
Preferably, the curing agent includes, but is not limited to, one of the following or a mixture of several thereof:
1-2 parts by weight of methyl ethyl ketone peroxide dimethyl phthalate solution;
1-2 parts by weight of cyclohexanone peroxide dimethyl phthalate solution.
Preferably, the promoter organometallic compound includes, but is not limited to, one of the following or a mixture of several thereof:
0.2-1 parts by weight of cobalt naphthenate;
0.2 to 1 part by weight of cobalt isooctanoate.
Preferably, the vinyl ester resin polymer cement mortar also comprises a polymerization inhibitor, wherein the polymerization inhibitor is a 10% styrene solution of tert-butyl ortho-phenol, namely the polymerization inhibitor contains 10% tert-butyl ortho-phenol and 90% styrene, and the weight part of the polymerization inhibitor is 0.01-0.05.
Preferably, the coupling agent includes, but is not limited to, one of the following: 1-2 parts by weight of organosilicon coupling agent, 1-2 parts by weight of titanate coupling agent and 1-2 parts by weight of aluminate coupling agent.
Preferably, the weight part of the water is 30% of the weight part of the portland cement.
Compared with the plain mortar, the vinyl ester resin polymer cement mortar has the advantages that the toughness of the vinyl ester resin polymer cement mortar is obviously improved, the shock resistance is excellent, the barrier property to gas and liquid corrosive substances is obviously enhanced, the carbonization and pulverization resistance of cement casting parts is greatly improved, and the service life is prolonged.
Compared with the modification of the polymer emulsion to the cement mortar, the strength and chemical resistance of the casting of the vinyl ester resin polymer cement mortar are far stronger than those of the polymer emulsion cement mortar in the cross-linked three-dimensional network structure of the vinyl ester resin polymer cement mortar.
Compared with common unsaturated polyester cement mortar, the vinyl ester resin polymer cement mortar has smaller curing shrinkage, small internal stress after curing, and is not easy to generate defects and stress concentration, and secondary hydroxyl of the vinyl ester resin polymer greatly improves the bonding force of resin to inorganic parts, so that the vinyl ester resin polymer cement mortar has higher strength than the common unsaturated polyester cement, has good bonding effect on cement concrete, and can be applied to repairing concrete pouring bodies such as roads and bridges, chemical pipelines, containers and the like in an operating state.
The active group of the vinyl ester resin is a carbon-carbon double bond provided by methacrylic acid, so that the cement mortar modified by the vinyl ester resin can be quickly cured under the action of a peroxide initiator and an accelerator, and meanwhile, the induction period can be prolonged under the action of a polymerization inhibitor, the reaction time is delayed, or the curing speed is increased by adding an accelerator, so that the cement mortar modified by the vinyl ester resin has good operability.
The vinyl ester resin has secondary hydroxyl groups which are the same as those of epoxy resin, has stronger bonding capability to inorganic filler or common concrete interface, and is not easy to crack and debond.
The ester group of the vinyl ester resin is introduced by methacrylic acid, the content of the ester group is far less than that of the unsaturated polyester, and a hydrophobic methyl group is arranged beside the ester group to provide steric hindrance, so that the hydrolysis resistance of the vinyl ester resin is far better than that of the unsaturated polyester.
The hydration process of common portland cement generally lasts for more than 5 hours, if the ordinary portland cement is hardened normally, the ordinary portland cement needs to wait for more than 5 hours, and during the period, the ordinary portland cement occupies a mold and a field, particularly emergency engineering, and is difficult to realize rapid construction and use.
The casting piece using the vinyl ester resin polymer cement does not need special maintenance, the hardening speed is high, gel hardening and demolding can be carried out within about 0.5 hour at normal temperature, the production efficiency of the vinyl ester resin polymer cement casting piece is greatly improved, and the geometric progression can be improved particularly in the field of emergency engineering.
Because the resin and the auxiliary agent in the vinyl ester resin polymer cement react and are adhered to the silicate cement and the quartz sand, particularly, the resin, the cement and the quartz sand can be firmly anchored together by the coupling agent, and the rapid gel hardening is realized under the combined action of the polymers such as the vinyl resin, the curing agent, the coupling agent and the like.
The interior of the ordinary portland cement casting is of a porous structure, and carbon dioxide in air can easily permeate into the portland cement casting, so that the portland cement casting and the portland cement concrete are subjected to carbonization reaction, namely the concrete is carbonized, and further pulverized and peeled. The resin in the vinyl ester resin polymer cement reacts with the auxiliary agent to enable the whole structure of the vinyl ester resin polymer cement casting to be compact, carbon dioxide in the air is difficult to permeate into the vinyl ester resin polymer cement casting, the carbonization corrosion process of the vinyl ester resin polymer cement casting is greatly delayed, and therefore the service life of the vinyl ester resin polymer cement casting is prolonged.
The polymer generated by the reaction of the resin in the vinyl ester resin polymer cement and the auxiliary agent has toughness, the toughness of the vinyl ester resin polymer cement casting is far beyond that of the common Portland cement casting, and the impact resistance is also far beyond that.
