Abstract
The invention relates to a polyurethane modified epoxy resin grouting material. The grouting material is characterized in that: the grouting material comprises an adhesive and a solid material according to a weight ratio of 1:4-8, wherein the solid material comprises coarse quartz sand, high aluminum cement, middle quartz sand, a pigment and fine quartz sand; and the adhesive comprises a polyurethane modified epoxy resin, a curing agent, an epoxy-based reactive diluent, a leveling agent, a defoamer and a dispersant. Compared with grouting materials prepared with the prior art, the polyurethane modified epoxy resin grouting material provided by the invention allows the toughness and the strength of the grouting material to be improved, the impact and the shock of mobile equipment to the base to be effectively reduced, the service life of the equipment and the base to be prolonged, better water resistance and oil resistance to be possessed and the cost to be reduced by about 50%.
Description
Technical field
The present invention relates to building material technical field, specifically refer to a kind of polyurethane modified epoxy resin grouting material.
Background technology
Along with the development of technology, the measure of precision of some moving equipment is more and more higher, and is also more and more higher to the requirement on basis, and especially the anti-seismic performance to the basis has proposed stricter requirement.For example use that the epoxy resin grouting material can effectively reduce the destruction of equipment vibrations to the basis between moving equipment and basis; simultaneously; because the epoxy resin grouting material is the chemical grouting material, it also has certain resistivity to acid-basicity, and equipment is played a very good protection.
But,, frangible during sharp pounding because the fragility of Resins, epoxy is big, to moving equipment more high-power and/or big speed, existing epoxy resin grouting material can not satisfy the more and more higher freedom from vibration and the requirement of shock resistance, and simultaneously, the cost of epoxy resin grouting material is also higher.Therefore, be badly in need of a kind of resistance to compression of exploitation and folding strength is higher and cost is low chemical grouting material, resonance that bridge is produced the destruction of travelling of vibrations that produced when avoiding moving equipment operation and vehicle to the basis.
Summary of the invention
Technical problem to be solved by this invention is that the present situation at prior art provides a kind of compressive resistance, shock resistance and freedom from vibration good polyurethane modified epoxy resin grouting material, to reach the purpose that improves polyurethane modified epoxy resin grouting material over-all properties.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: this polyurethane modified epoxy resin grouting material, and it is characterized in that comprising tackiness agent and solid-state material, tackiness agent: the weight ratio of solid-state material is 1: 4～8;
Wherein, the weight of described solid-state material consists of:
The weight of described tackiness agent consists of:
Polyurethane modified epoxy resin 100%
Solidifying agent 40～50%
Epoxy group(ing) reactive thinner: 10%～18%
Flow agent: 1%～3%
Defoamer: 1%～3%
Dispersion agent: 1%～3%
Preferably, the preferred fluorine-carbon modified polypropylene esters of gallic acid of above-mentioned flow agent, 3777 types of for example Dutch Fu Ka company; 510 types that 660 types that the preferred Shanghai Resin Factory of described epoxy group(ing) reactive thinner produces or Yixing three wooden groups produce.
Described defoamer can be selected for use and contain silicon defoamer, 2722 types that for example Dutch Fu Ka company produces; The preferred high score subclass of described dispersion agent dispersion agent, for example Dutch Fu Ka company 4010 types.
The preferred low-expansion coefficient of described solidifying agent, low heat-generation system and the good solidifying agent of toughening effect, better, the C-1 type solidifying agent that can select for use Suzhou tannery to produce.
The preparation method of above-mentioned polyurethane modified epoxy resin grouting material, it is characterized in that comprising earlier described polyurethane modified epoxy resin and described solidifying agent poured in the agitation vat and mix, and then described solid-state material poured in the agitation vat, be stirred well to solid-state material and all soak into, promptly obtain polyurethane modified epoxy resin grouting material.
Compared with prior art, polyurethane modified epoxy resin grouting material provided by the present invention not only has epoxide group, has urethano and hydroxyl, phenolic group isoreactivity group simultaneously, gives the grouting material higher bonding strength and toughness; And the alicyclic ring ammonia and the polyetheramine that are adopted in the solidifying agent, the toughness and the intensity of grouting material have then further been improved, make the ultimate compression strength (28 days) of grouting material can reach 120MPa, folding strength (28 days) can reach about 32MPa, and the maximum compressive strength (28 days) of high-quality grouting material only is 110MPa in the prior art, maximum folding strength (28 days) only is about 25MPa, has effectively reduced impact and the vibrations of moving equipment to the basis, has prolonged the work-ing life on equipment and basis; Simultaneously, because polyurethane modified epoxy resin has the dual performance of Resins, epoxy and urethane simultaneously, so have better water tolerance and oil-proofness; Compare with the epoxy resin grouting material, its cost has reduced about 50%.The present invention is particularly suitable for the technical formula of dry mortar.
Embodiment
Below in conjunction with embodiment the present invention is described in further detail.
Prepare solid-state material by following weight ratio:
