Description
Technical field
The present invention relates to a kind of building energy conservation mortar, particularly a kind of inorganic mineral earth surface insulating mortar.
Background technology
Mortar is a kind of material that building trade is generally used; Reach the purpose of building energy conservation, one of its main path is exactly to adopt the heat-insulating mortar.China is the country of an energy, resource scarcity, and research and development novel heat insulation and preservation mortar can be obtained high economic benefit and social benefit.
At present, the building heat insulation measure of China is mainly adopted on the inside and outside insulation of exterior wall and roofing heat preservation and insulation layer.The internal partition wall of buildings, building ground, each floor, top ceiling are not all considered conservation measures.Because internal partition wall, flooring do not have heat preservation and insulation, between the floor of backfence partition wall face, levels (top ceiling), just formed cold and hot bridge, summer room conditioning refrigeration, winter indoor open heating installation, just upwards floor infiltration downstairs is unfavorable for effectively energy-conservation and causes the wasting of resources.
Summary of the invention
The technical problem to be solved in the present invention provides the inorganic mineral earth surface insulating mortar that a kind of heat-insulating property is good, cohesive force is strong, ultimate compression strength is high.
In order to solve the problems of the technologies described above, the invention provides a kind of inorganic mineral earth surface insulating mortar, it is made by the following weight proportion raw material: the general cement 50-60 of 42.5-52.5 level part, unit weight 100-130kg/m
3Pitchstone glass bead 30-40 part, I-II level high-calcium fly ass 2-3 part, naphthalene series high-efficiency water-reducing agent 0.4-0.6 part, 8000-10000 viscosity SMP inorganic gel 0.5-1 part, 3-5 (are that viscosity is 30000～50000Mpa.s) Vltra tears 0.1-0.2 parts, activation modification microdilatancy zeolite powder 4-8 part, composite glue powder for mortar 0.5-1 part, anti-cracking impervious agent 1-2 part and PVA high modulus fibre 0.05-0.1 part for ten thousand grades.
Improvement as inorganic mineral earth surface insulating mortar of the present invention: general cement is 42.5 grades of ordinary Portland cements.
Inorganic mineral earth surface insulating mortar of the present invention is that various components (raw material) are dropped into whipping device, gets final product to mixing in mechanical stirring 5-10 minute, is the dry powder thing.
In the present invention, various components function as follows respectively:
1, unit weight 100-130kg/m
3The pitchstone glass bead:
Adopt grinding to 30～50 order fineness, through the pitchstone glass bead (vitreous cenosphere) that the instantaneous expansion of high-temperature roasting makes, it can have 100-130kg/m
3Unit weight.Its volume is moderate, intensity is high, have air adiabatic performance preferably, also has the little characteristic of water-intake rate.
2, activation modification microdilatancy zeolite powder:
The main component of zeolite is a silicon-dioxide, and the characteristics of its bond structure cause its surface and have a large amount of available electrons, makes it have very high surface tension, can adsorb a large amount of water moleculess and radius positively charged ion at a low price, therefore can increase the ultimate compression strength of mortar.
Its good adsorption performance can and be stored in interior bore with many material absorption, and slowly releases when ambient conditions changes.Modification microdilatancy zeolite powder has very strong alkali absorption property, can effectively suppress alkali-aggregate reaction, and has performances such as the mortar of delaying aquation, heat release, prevention temperature difference cracking, also has good heat-insulating property simultaneously.
3, SMP inorganic gel:
Its cohesive strength can reach 8000～10000Mpa.s, has good thickening plasticity-maintaining effect.
4, naphthalene series high-efficiency water-reducing agent:
The naphthalene series high-efficiency water-reducing agent that the present invention is selected can make the mortar water reducing ability strengthen, and improves mobile.
5, PVA high modulus fibre (high-strength high elasticity modules polyethylene alcohol fiber)
This PVA high modulus fibre is a kind of macromolecular material that adopts the fiber making equipment, makes with high-quality synthetic resins raw material, its have good intensity, dispersiveness and with the cohesiveness of concrete substrate.The PVA fiber as in concrete, mix several hundred million three-dimensional disorderly to the fine ribs of substep, so the PVA fiber can play the inhibition concrete cracking, reaches the purpose of improving concrete performance.And characteristics such as the PVA fiber has good dispersity, diameter is little, weather resistance is high, bond stress is strong, Environmental Safety.
6, anti-cracking impervious agent
This anti-cracking impervious agent has effects such as water-keeping thickening, compensate for shrinkage, closely knit enhancing, anti-cracking impervious and hydrophobic waterproof.
Therefore, inorganic mineral earth surface insulating mortar of the present invention has the following advantages:
1, ultimate compression strength of the present invention is 2.2MPa, is higher than the standard of GB GBT200473-2006 " building heat-insulating mortar " far away.
2, therefore linear shrinkage of the present invention≤0.16 is difficult for causing shrinkage cracking;
3, the present invention when the heat insulation depth of plastering on ground is 20-25mm, can reach effect of heat insulation when reality is used; Therefore can save material.
In sum, inorganic mineral earth surface insulating mortar of the present invention have that the volume water absorption amount is low, ultimate compression strength is high, heat insulation and good heat insulating, dry-shrinkage deformed little, advantage such as cohesive force strong, permeable watertight, weather-proof weather resistance are good.
Inorganic mineral earth surface insulating mortar of the present invention can satisfy the requirement of national building energy conservation more than 50% fully, is particularly suitable for heat insulation, the heat insulating work construction application of ground that Xia Redong cryogenic region, hot summer and warm winter region and weather leniently distinguish, interior wall, passage.
