Description
Technical field
The present invention relates to a kind of nano hydrophobic thermal insulation material and preparation method thereof, belong to building material technical field, product is used in the heat-proof insulation waterproof of interior exterior wall, roofing, vault etc.
Background technology
In recent years, along with the raising of environmental protection and " green " engine request, building energy conservation is extremely urgent, and building energy conservation has become the main contents of carrying out national environmental protection and save energy policy, becomes the important component part of implementing national economy sustainable development.The rational Application of development External Walls Heating Insulation and insulating wall material is to realize the main mode of building energy conservation.Existing heat-insulation and heat-preservation material mainly contains inorganic and organic heat-insulation and heat-preservation material two big classes, the fire prevention ageing resistance of inorganic heat insulation material is good, but water-repellancy is poor, and water is the formidable enemy of external thermal insulation system, when external thermal insulation system seeps water or leaks, heat-insulating property is reduced, even completely lose.In winter, the volumetric expansion 9% of can freezing of the water of infiltration, thus producing expansion stress, these can cause catastrophic destruction to external thermal insulation system.Rodent gas is as CO
2, SO
2Deng, also be to become acid by water to cause external thermal insulation system to damage, simultaneously moisture also can with interactions such as plaster, gypsum, thereby cause thermal insulation layer efflorescence, come off.And organic heat-insulation and heat-preservation material mainly contains polystyrene and urethane, though this class material has less thermal conductivity, but fire line is poor, produces obnoxious flavour during high temperature, and easily degraded is aging, life-span is short, for example the patent No. is ZL200410013231.2, and denomination of invention is heat insulation heat preservation energy-saving waterproof and method for formulating thereof, the granular polystyrene in the used batching, just there is above-mentioned shortcoming, so China lacks the good inorganic heat insulation material of effective heat insulation heat preservation energy-saving waterproof.
Summary of the invention
Problem to be solved by this invention is exactly to provide a kind of nano hydrophobic thermal insulation material at the deficiency of above-mentioned prior art existence, it has excellent hydrophobic, thermal and insulating performance and fire prevention ageing-resistant performance (can with same life-span of buildings), not hollowing cracking, ultimate compression strength and cohesive strength height, and compound method and construction technology are simple, easy to operate, constant product quality, the pollution-free feature of environmental protection.
The technical scheme of nanometer hydrophobicity heat-insulation and heat-preservation material of the present invention is: nano hydrophobic thermal insulation material, and it is formulated by A component and B component, and wherein the A component is composed of the following components, counts by weight:
Emulsion polymerization: 500～600
Modified polypropylene fiber: 2～3
Nm-class active calcium carbonate: 500～600
Silicate mineral: 30～48
Described emulsion polymerization is any one or the multiple mixing in acrylic type emulsion, styrene-acrylic emulsion, polyvinyl alcohol type emulsion, polyethylene vinyl acetate type emulsion, Mierocrystalline cellulose emulsion, the ether of cellulose emulsion; described silicate mineral is glass bead or perlite
It is standby to organize the grouping of 40 parts by weight by each after mixing, and has some groups;
The B component is composed of the following components, counts by weight:
Cement: 6～8 is one group;
In use, A component and each the one group of mixing of B component are mixed thoroughly, promptly get nano hydrophobic thermal insulation material.
Preparation method's of the present invention technical scheme is: it comprises the steps:
The first step: preparation A component:
A. the weight part of each component is:
Emulsion polymerization: 500～600
Modified polypropylene fiber: 2～3
Nm-class active calcium carbonate: 500～600
Silicate mineral: 30～48,
Described emulsion polymerization is any one or the multiple mixing in acrylic type emulsion, styrene-acrylic emulsion, polyvinyl alcohol type emulsion, polyethylene vinyl acetate type emulsion, Mierocrystalline cellulose emulsion, the ether of cellulose emulsion, and described silicate mineral is glass bead or perlite;
B. mix: the emulsion polymerization raw material is added in the agitator stir, add modified polypropylene fiber and nm-class active calcium carbonate again and stir 10-30min, silicate mineral is added stir 5～10min at last, promptly get the A component to evenly;
C. packing A component: mix the back and organizes the grouping of 40 weight parts, have some groups by each;
Second step: preparation B component:
By one group of 6-8 weight part grouping, has cement at least one group;
The 3rd step: the mixed preparing before the construction:
A. get the raw materials ready in the ratio of one group of component A and one group of B component;
B. in use, A component and the mixing of B component two components got ready are mixed thoroughly, promptly get nano hydrophobic thermal insulation material.
Characteristics of the present invention are:
1. product of the present invention belongs to inorganic heat insulation material, its long service life (can with same life-span of buildings), ageing-resistant, fire resistance is good, having substituted the patent No. with perlite or glass bead is expanded polystyrene particle in the technical scheme of the ZL200410013231.2 used batching, make the long service life (can with same life-span of buildings) of product, fire protection flame retarding is good;
2. with the A component water-intake rate bigger perlite or glass bead have been carried out surface treatment, make the surface wettability of perlite or glass bead that counter-rotating take place, transform for hydrophobic nature by original water-absorbent, make material itself have hydrophobicity performance, had " lotus leaf effect ", promptly water droplet becomes globule shape on material, just as water droplet on lotus leaf, water is not absorbed by material;
3. having substituted the patent No. with nm-class active calcium carbonate is calcium stearate or Zinic stearas in the masterbatch used in the technical scheme of ZL200410013231.2, because of the thermal conductivity of nm-class active calcium carbonate little than treated carbonates, so adding of the nm-class active calcium carbonate that heat-proof quality is good, make the thermal conductivity of material diminish, heat preservation and insulation is better, better in the actual application in engineering effect of a plurality of roofings, through actual detected, on the steel tile roofing of factory building, do thick this material of 1cm, can make the roofing temperature reduce by 10～15 degree, the house roof temperature reduces by 8～10 degree.
4. ultimate compression strength and cohesive strength are good, do not ftracture, and do not come off environmentally safe;
5. the product workability is good, is convenient to construction, and the duration is short.
