Background technology
The heat preservation energy-saving of buildings receives publicity day by day in recent years, has wherein emerged a large amount of outstanding heat insulating products, and wherein major part is the product that belongs to the mortar class, excellent thermal insulation performance, with low cost and coating series products can widespread use is less.Chinese patent publication number: 1539893A, open day: on October 27th, 2004, denomination of invention " a kind of bicomponent environment-friendly type heat-insulation and heat-preservation anti-crack mastic ", proposed the component by A: organic high molecular polymer, moistening temperature agent, defoamer, freedom from cracking agent and B component: cenosphere, water-holding agent, fortifying fibre, white cement, coarse whiting, silica powder, wollastonite powder are in 1: the ratio of 1.1-1.6 is formulated.Owing to added cenosphere and fortifying fibre, make the putty of producing to guarantee that enough once criticizing scrape thickness, also strengthened the heat-insulation and heat-preservation effect of body of wall simultaneously, effectively prevented the putty layer cracking, it utilizes the heat reflection and the hollow insulating heat-blocking action of hollow glass micropearl, improve heat insulating effect, the toxicity of coating is less, and energy saving is higher.But above-mentioned coating belongs to simple heat resistance type coating, and used heat preserving and insulating material is more single, and filming of hollow glass micropearl periphery is difficult to form the insulation barrier layer, and heat insulation effect is desirable not to the utmost; The weathering resistance and the contamination resistance of coating are relatively poor, and the tension resistance to cleavage also has much room for improvement.
Summary of the invention
It is perfect inadequately to the objective of the invention is to overcome existing thermal insulation coatings insulation barrier layer, weathering resistance and contamination resistance are relatively poor, defective that the tension splitting resistance is lower and deficiency, provide a kind of its to film and be easy to form good insulation barrier layer, weathering resistance, contamination resistance and tension resistance to cleavage are better, use and allocate polymer microsphere insulation heat-proof bedding putty easily.
Technical solution of the present invention is: a kind of polymer microsphere insulation heat-proof bedding putty, form by the raw material of following weight part: water-ground limestone 35-65, hollow glass or ceramic fine bead 10-15, polymer microballoon 20-30, tubular fibre 2-5, latex powder 3-15;
After water-ground limestone and hollow glass or ceramic fine bead and latex powder mixed, add polymer microballoon, sneak into tubular fibre at last and mix the back.
The particle diameter of hollow glass of the present invention or ceramic fine bead is the 50-100 micron, the particle diameter of polymer microballoon is the 10-40 micron, tubular fibre is PET Hollow fiber or polypropylene hollow fiber or pure aluminium silicate tubular fibre, and its diameter is the 20-40 micron, and length is the 0.5-2 millimeter.
The present invention can use the polymer microballoon of making by existing emulsion polymerization or suspension polymerization, but preferably adopt the applicant in what apply on the same day, denomination of invention is that " a kind of polymer hollow microsphere and preparation method thereof " prepared polymer hollow microsphere and/or denomination of invention are " a kind of polymer phase-change microsphere and preparation method thereof " prepared polymer phase-change microsphere.
Polymer microballoon of the present invention is formed by polymer hollow microsphere and the polymer phase-change microsphere mixed by weight 0-1: 0-1.
The particle diameter of polymer hollow particles of the present invention is the 20-40 micron, and the particle diameter of polymer phase-change microsphere is the 10-20 micron.
The water proof anti-seepage of 5-10 adding by weight additive in the raw material of the present invention.
The invention has the beneficial effects as follows: at first the present invention has adopted double glazing or ceramic microsphere and polymer microballoon, because the structure of phase change material or hollow negative pressure in the polymer microballoon, make coating have the common feature of heat resistance type and thermal capacitance section bar material concurrently, comparing the simple heat resistance type of existing insulating mold coating is a progress and innovation; Secondly, lower at existing insulating mold coating weather resistance, the defective that contamination resistance is relatively poor, inorganic-organic compound form that the present invention adopts has outstanding weather resistance and good especially contamination resistance; The 3rd, used tubular fibre to strengthen in the claircolle of the present invention, increased substantially tension cracking resistance fracture resistance, simultaneously tubular fibre also has good heat insulating effect, thus the perfect thermal and insulating performance of putty; At last, putty of the present invention is pressed the mutual grating of particle diameter by hollow glass or materials such as ceramic microsphere, tubular fibre and polymer microballoon, the good barrier layer that made the putty material intermediate formation has reduced the cold and hot bridge of putty intermediary, has further improved thermal and insulating performance.
