Abstract
The invention discloses an inner thermal insulation system of an outer granulated cork wall, which is composed of granulated cork and complex additive. The complex additive comprises polymer resin adhesive powder, lignocellulose, strain fiber, water-retaining agent and the like. The product provided by the invention remarkably improves thermal insulation performance, sound insulation effect and crack resistance of mortar materials.
Description
Technical field
The present invention relates to plaster material for building, specifically inner thermal insulation system of outer granulated cork.
Background technology
Cork is commonly called as " cork ".The pinacocyte that cork is arranged by many radiation forms, and typical cell dia is 30 microns, and cell thickness is 1～2 micron, duct free between cell.In every 1 cubic centimetre, have 4,000 ten thousand above cells, lumen contains resin and tannin compound, and cell is honeycomb arrangement, is full of air in cell.Each cell is a small-sized pressure absorber, and each cell is a small-sized damper, thereby cork quality is light and soft, high resilience, waterproof, be not subject to the effect of chemicals, cork proportion only has 0.24, and is the non-conductor of electricity, hot harmony.Cork article has extraordinary sealing, thermal insulation, sound-proofing, electrical insulating property, rub resistance, mothproof, corrosion resistant, protection against the tide, and nontoxic, tasteless, proportion is very little, soft, be difficult for catching fire, belonging to the advantages such as renewable resource.The heat-insulating property of cork and soundproof effect are better than building 20 times of brick mix structures.
The building mortar of existing market is main mainly with raw materials such as cement and limes greatly, and the insulation for building there will be so-called " cold-heat bridge " problem like this." cold-heat bridge " refers to the general name to same building object north and south section.Such as the lintel in house or collar tie beam, choose (or exposing) outdoor part because being shined upon " heat ", indoor section is " cold " relatively, for heat transmission, Here it is one " cold and hot transmission bridge "; Certainly, if heating within doors, temperature is compared with high outside room, and at this moment part is " heat " within doors, and outside, room is divided into " cold ", and this is still " cold-heat bridge ".A major reason of generation of " cold-heat bridge " is relevant with adopted compo material.In addition, the soundproof effect of traditional architecture plaster material is not remarkable, and it is heavy again, easily crack, and use inconvenience.So, provide a kind of and novel can be incubated, can sound insulation, lightweight, cracking resistance seam building mortar product easy to use again, be the problem that needs research.
Summary of the invention
In order to address the above problem, the invention provides inner thermal insulation system of outer granulated cork, refer to a kind of mortar, it is compared with conventional grout material, has advantages of good insulation, sound insulation, amount gently and cracking resistance; Compare with conventional grout using method, have advantages of easy to use.
Inner thermal insulation system of outer granulated cork, it is comprised of granulated cork and compound additive.
Granulated cork and compound additive be take weight ratio as benchmark, and its constituent content is: granulated cork: 60%, and compound additive: 40%.The order number of granulated cork is between 40-80 order.
A kind of compound additive be take weight proportion and is constructed as follows as basic component and content:
1. fluoropolymer resin rubber powder 70%-90%
2. lignocellulosic 2.5%-10%
3. resistance to towing tieed up 1.5%-9%
4. water-loss reducer 5.5%-15%
Described inner thermal insulation system of outer granulated cork is approximately mixed by the volume ratio of 3: 2 with water, fully stir into micro-rare paste, for using the building outer wall of cement mortar Troweling press finishing, it has the performance that thermal insulation separation volume is light.
Another kind of compound additive be take weight proportion and is constructed as follows as basic component and content:
1. fluoropolymer resin rubber powder 15%-40%
2. lignocellulosic 1.5%-2%
3. resistance to towing tieed up 1.2%-1.5%
4. antimitotic agent 1.5%-1.8%
5. water-loss reducer 2.5%-2.7%
6. white cement 20%-45%
7. coarse whiting 4%-30%
8. calcium formate 3%-4.5%
Described inner thermal insulation system of outer granulated cork is approximately mixed by the volume ratio of 3: 2 with water, fully stir into micro-rare paste, for not using the building outer wall of cement mortar Troweling press finishing, it has the performance of the light cracking resistance of thermal insulation separation volume.
In two kinds of compound additives as above:
Fluoropolymer resin rubber powder be take the redispersible latex powder of VAC/VeoVa/E copolymerization as main.
The resistance to dimension of towing is for 3mm.
Water-loss reducer is methylcellulose.
This product has good insulation, soundproof effect, effectively alleviate construction wall deadweight, energy-saving and environmental protection, special convenient construction, greatly reduce the various link of traditional heat preservation construction, very meaningful to solving building heat preservation " cold-heat bridge " problem, be the novel energy-saving environment-friendly new building material in the market with obvious price advantage.
The specific embodiment
Inner thermal insulation system of outer granulated cork, granulated cork and compound additive be take weight ratio as benchmark, and its constituent content is: granulated cork: 60%, compound additive: 40%.The order number of granulated cork is between 40-80 order.
A kind of compound additive be take weight proportion and is constructed as follows as basic component and content:
Fluoropolymer resin rubber powder 35%
Lignocellulosic 2%
The resistance to dimension 1.5% of towing
Antimitotic agent 1.8%
Water-loss reducer 2.7%
White cement 40%
Coarse whiting 12.5%
Calcium formate 4.5%
The using method of inner thermal insulation system of outer granulated cork: for the construction wall of not using cement mortar Troweling press finishing, first granulated cork and compound additive are mixed into the described granulated cork exterior wall internal insulation mortar of powdery, then approximately by the volume ratio of 3: 2, mix with water, fully stir and make micro-rare paste, with grey cutter, be directly applied to exterior wall, blade coating is smooth.
Be one group of experimental result below, express the technical performance index of this product:
Wet apparent density: 180kg/m
3
Dry apparent density: 96kg/m
3
Thermal conductivity coefficient: 0.046w (m.k)
Water absorption rate :≤15%
Linear contraction :≤0.35%
Sound-absorption coefficient: 0.92a
Combustibility: B1 level
From above experimental data, can find out, the heat insulating ability of this product, sound-proofing and crack resistance have all had large increase than traditional plaster material.
