Description

Single unit heat-insulating dry mortar and production method thereof

Technical field

The present invention relates to a kind of novel construction wall heat-insulation and heat-preservation material.

Background technology

In recent years, China's construction scope enlarges rapidly.It is estimated that the building energy consumption account of China society total energy consumption proportion surpasses 27.25% in recent years, the heating energy consumption of northern area surpasses 40% of local social total energy consumption.The greenhouse gas emissions that architectural energy consumption produces have surpassed 1/4 of national total displacement.The immense pressure of aspects such as the energy that architectural energy consumption causes, environmental protection has caused that the Chinese government pays much attention to.Building energy consumption basic reason be the famine of the materials for wall of insulation type.In order to build the energy-saving society of resource, make China's economy continue, steadily, develop in a healthy way, must cut down the consumption of energy, save resource.Along with the enforcement of " building a conservation-minded society " this development general plan, be made as inevitable more scientific, the rationalization of Chinese national economy growth pattern of main motive force with infrastructure construction.Therefore developing novel building heat preservation heat insulation type material solution resource regeneration is the key subjects of pendulum in face of building trade.

Summary of the invention

At the severe situation and the national requirement to new building insulation material of the proportion of building energy consumption in consumes energy, purpose of the present invention aims to provide a kind of single unit heat-insulating dry mortar that is used for body of wall.Main body as foundation construction---body of wall, its heat insulation property will become efficent use of resources, realize the key factor of sustainable development.

Another object of the present invention provides one-component and does the production method of mixing thermal insulation mortar

Purpose of the present invention can be achieved through the following technical solutions:

A kind of single unit heat-insulating dry mortar is characterized in that component and percentage by weight are respectively:

A kind of one-component is done and is mixed the thermal insulation mortar preparation method:

With the HF organosilicon moisture repellent by air compressor machine to common perlite pellet, in concrete drum, spray homogenizing and handle, the oven dry back hydrophobic expansion pearlite, stand-by;

After useless EPS is ground into the particle of particle diameter≤5mm with pulverizer, in mixer, sprays an amount of HF908 glue and ordinary cement premixing and wrap up in the shell heap and support stand-by after 7 days;

Then with above-mentioned through good hydrophobic expansion pearlite of preliminary treatment and hard shell polystyrene foam particles metering back adding mixer, again ordinary cement, one-level dry powder coal ash are added mixer premix 1-3min, and then adding re-dispersible glue powder, the water-soluble cracking resistance rubber powder of HF-2000, polyacrylamide, hydroxypropyl methylcellulose, the polypropylene chopped strand, lignin fibre, neopelex mixing 5-10min can be packaged into finished product after the mixing.

Characteristic and the role of above-mentioned each raw material in single unit heat-insulating dry mortar:

Treated hydrophobic pearlite, hard shell polystyrene foam particles have good insulation effect, hydrophobic expansion pearlite can reduce intergranular voidage, reduce the self-constriction of coursing degree of mortar and mortar, good anticracking effect is arranged, hard shell polystyrene foam particles is easy to other material and realizes evenly mixing, and has also solved the white pollution that causes because of the scene preparation;

The effect that ordinary cement, one-level dry powder coal ash all can reach bonding, strengthen;

Re-dispersible glue powder has higher resistance to water, pliability frost resistance and wear resistence;

The water-soluble cracking resistance rubber powder of HF-2000 has performances such as tackify, water conservation, anticracking be freeze proof;

Polyacrylamide mainly plays tackify, improves the levelability of mortar;

Hydroxypropyl methylcellulose has better thickening and improves adhesive effect;

Polypropylene chopped strand, lignin fibre can well improve the cracking resistance of mortar; Have impervious preferably, anti-impact mill property, can play good little arrangement of reinforcement effect, and prolong the service life of engineering greatly;

Neopelex mainly improves the workability of mortar.

The characteristics that the present invention has and the beneficial effect of generation are:

Single unit heat-insulating dry mortar is Binder Materials with the polymer cement, adopt chemical resistances such as hydrophobic expansion pearlite and hard shell polystyrene foam particles good, do not absorb water, lightweight aggregate that heat insulation property is good and import re-dispersible glue powder, high-quality additives such as anti-crack fiber, hybrid technique by uniqueness evenly mixes.It has good heat-insulation and heat-preservation, whitewashes cementability, and crack resistance, weatherability and application property can substitute traditional mixing motar, again can be with good heat preservation energy-saving effect, and the heat preservation construction of the on-the-spot combined wall of the paste heat-preserving plate of replace complex.Single unit heat-insulating dry mortar after testing: do superficial density≤230kg/m ³Thermal conductivity factor≤0.06w/ (m.k); Compressive strength≤200kpa; Linear shrinkage≤0.3%.
