Technical field
The present invention relates to a kind of architectural decoration external and internal wall coating, especially a kind of polymer microsphere insulation heat-proof dry-powder paint.
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: 101108930A, open day: on January 23rd, 2008, denomination of invention " a kind of aquosity heat insulating heat preserving paint and production method " has proposed employing elastomeric propylene acid modified emulsion, Resins, epoxy, ethylene glycol, hollow glass micropearl, functional filler, kaolin, talcum powder and other auxiliary agents are formulated and heat insulating coatings.Heat reflection and hollow insulating heat-blocking action that it utilizes hollow glass micropearl improve heat insulating effect, and 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 dry-powder paint easily.
Technical solution of the present invention is: a kind of polymer microsphere insulation heat-proof dry-powder paint, raw material by following weight part is formed: water glass powder 20-40, closed-cell expanded perlite 8-15, hollow glass or ceramic fine bead 3-15, polymer microballoon 10-30, tubular fibre 2-5, Sodium Silicofluoride 3-5, latex powder 5-10, water proof anti-seepage additive 5-10;
After water glass powder and hollow glass or ceramic fine bead and closed perlite mixed, adding polymer microballoon and latex powder mixes, join after water proof anti-seepage additive and Sodium Silicofluoride are pre-mixed in the above-mentioned miscellany and to continue to mix, sneak into tubular fibre at last and mix the back.
The particle diameter of closed-cell expanded perlite of the present invention is the 150-200 micron, the particle diameter of hollow glass 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, its diameter is the 20-40 micron, and length is the 0.5-2 millimeter.
Polymer hollow microsphere of the present invention preferably adopts the applicant to be " a kind of polymer hollow microsphere and preparation method thereof " prepared polymer hollow microsphere in the denomination of invention of application on the same day, and described polymer phase-change microsphere preferably adopts the applicant to be " a kind of polymer phase-change microsphere and preparation method thereof " prepared polymer phase-change microsphere in the denomination of invention of application on the same day.
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 microsphere of the present invention is the 20-40 micron, and the particle diameter of polymer phase-change microsphere is the 10-20 micron.
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 coating of the present invention, increased substantially tension cracking resistance fracture resistance, tubular fibre also provides good heat insulating effect simultaneously, thereby has improved the thermal and insulating performance of coating; The 4th, coating 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, make and the good barrier layer of having filmed intermediate formation to have reduced the cold and hot bridge of the intermediary of filming, further improved thermal and insulating performance.At last, compare the form of existing insulating mold coating with the liquid supply, the present invention adopts the dry powder material supply, greatly reduces transportation cost and storage cost, is convenient to accumulating and construction.
