Description

A kind of preparation method of the modified adhering and sealing grouting material of silicon nitride nano particles
Technical field
The present invention relates to assembled architecture Material Fields, and in particular to a kind of modified adhering and sealing of silicon nitride nano particles The preparation method of grouting material.
Background technique
Compared with traditional mode of construction, the construction speed of assembled architecture is fast, and climate conditionality is small, can be with Improve construction quality.It is from rushing about prefabrication for from operation mode.The construction member base of assembled architecture This is completed in the factory, is then transported to project building site and is carried out general assembly, has greatly saved man power and material.
With the rise of assembled architecture industry, a series of problems occur restricts its fast development.Assembled architecture Exterior Wall Components many splicing seams can be generated after splicing, inevitably encounter processing splicing seams problem.Place at present The sealing material of reason Side fascia splicing seams has two classes.One kind is sealant, sealant the problem is that cannot be long-term heat-resisting, It is especially easy to produce bubble and crackle under high temperature environment, and then influences adhesive strength;Another kind of is cement mortar, such close Closure material is also easy to leak the problem is that adhesive strength is low.With the development of society, shared by assembled architecture It is more increasing than regular meeting, to change above-mentioned status, now traditional grouting sealing material is modified and is studied.Mine is being mixed again It joined silicon nitride nano modified particles in the cement-based material of slag, the closely knit internal structure of cement-based material improves filling Starch sealing material adhesive strength in a high temperauture environment.
CN103496936A discloses a kind of prefabricated member splicing seams gypsum base sealing material and its application, component Are as follows: waste gypsum, active mineral admixture, water-reducing agent, exciting agent, adjustable solidification agent, bonding agent, air entraining agent, plasticity-maintaining agent, hydrophober form sediment Powder enzyme, thixotropic lubricant, powder filler, aggregate.Though the sealing material fillibility is good, adhesion strength is strong, and cost is relatively low;But no Provide specific experimental data, it is not known that specifically have the improvement of much degree to adhesive property.And gypsum base sealing material Water resistance is poor, the seepage problem being easy to happen at splicing seams.
CN106220105A discloses a kind of concrete and quickly repairs composition polymer cement mortar and preparation method thereof, Its component are as follows: cement, quartz sand, agstone, polymer emulsion, defoaming agent, powder water-reducing agent, iron powder, flocculation aid, poly- third Alkene fiber, remaining is water.Though the invention can reduce the shrinking percentage of cement mortar, concrete can be improved and quickly repair compound gather The adhesive strength for closing object cement mortar and old concrete, improves its mechanics under severe cold environment, durable and workability, but The polymer cement mortar presetting period is too short, and the mix and transport to cement mortar propose very high requirement, it is difficult to extensively Applied to assembled architecture industry.
Summary of the invention
The purpose of the present invention is to provide it is a kind of can improve splicing seams interfacial adhesion strength, wear-resisting property, compression strength, The preparation method of the modified adhering and sealing grouting material of the silicon nitride nano particles of water resistance.
The implementation of the object of the invention is a kind of preparation of the modified adhering and sealing grouting material of silicon nitride nano particles Method, the specific steps are as follows:
1) it disperses 0.7-1.3 parts of silicon nitride nano particles of mass fraction in ethyl alcohol, under mechanical stirring, 0.2- is added 0.3 part of PEG silane is reacted 2 hours in 30-40 DEG C, reaction solution is centrifuged, freeze-drying process, obtains modified silicon nitride nano Particle;
The PEG silane is silane polyethylene active rouge, molecular formula: C2n+12H4n+20On+9N2Si;N=15- 105 or ammonia Base Active Ester of Polyethyen Glycol, molecular formula: C2n+11H4n+27On+4N2Si, n=16-107;
The freeze-drying condition: -30~-20 DEG C, 100~120Pa of vacuum values;
2) 100 parts of ordinary portland cements of mass fraction are taken, 10-20 parts of micron order Iron Ore Powder, 0.5-1 parts of thixotropings lubricate Agent, step 1) gained is silicon nitride nano particles 1-1.5 parts modified, and 2-4 parts of epoxy resin latex, 30-40 parts of water, in blender In stir to get grouting material;
The thixotropic lubricant is sheet silicate mineral material;
The epoxy resin latex is glycidyl ether type epoxy resin emulsion or glycidyl ester epoxy resin cream Liquid;
3) it takes grouting material obtained by step 2) that mass fraction 5-10 parts of sulphate aluminium cement and 3-5 parts of desulfurized gypsums are added, mixes Conjunction is uniformly mixing to obtain adhering and sealing grouting material.
The present invention using micron order Iron Ore Powder replace a part of clinker, on the one hand reduce cement somehow dosage, On the other hand the anti-permeability performance of grouting sealing material is improved again.Micron order Iron Ore Powder is filled in the gap of cement granules, is risen The effect that refinement inside concrete aperture is connected to hole number with reduction has been arrived, porosity has been greatly reduced, improves concrete Density.
For nano-silicon nitride through coupling agent treatment, there is a large amount of silicone hydroxyl on surface.And a large amount of existing silicone hydroxyls and silane Polyethylene active rouge or the polar group of amino-polyethyleneglycols active ester produce chemical bonding, increase silicon nitride nano Space steric effect around modified particles reduces the free energy on silicon nitride nano modified particles surface, improves silicon nitride Dispersibility of the nano modification particle in cement system, enables silicon nitride nano modified particles to be uniformly filled in cement bonded sand In the hole of slurry, reduce harmful hole inside mortar, improve the defect inside mortar, to improve grouting sealing Adhesive strength, wear-resisting property between material and splicing seams interface in a high temperauture environment, compression strength, water resistance.
