Description
Technical field: the present invention relates to a kind of heat preservation plate material and preparation method thereof, especially a kind of novel polyphenyl particulate perlite organic composite insulation material and preparation method thereof, belong to building material technical field.
Background technology: along with the development of China in Recent Years economy, improving constantly of living standards of the people and industrialized level, for the consumption of the energy, especially oil, the consumption of the non-renewable energy resources such as coal is continuously increased, and objectively proposes higher requirement for energy-conservation.In the total energy consumption of China, building energy consumption accounting is more than 30 percent, and the unit are power consumption of China's existing building is two to three times of developed country.In building energy consumption, the overwhelming majority is all used for heating and air conditioner refrigerating.Along with the home penetration rate of the people's being continuously increased higher level life requirement, heating and air conditioner facility is also gradually increased, also increasing therewith of corresponding building energy consumption.If the heat conductivity accounting for the body of wall of building overwhelming majority area is excessive, heat can conduct via building masonry wall faster, increases the weight of the burden of constructure heating or refrigeration, directly results in the consumption of the energy.
In current wall thermal insulating heat-barrier material, widely used method is to utilize loose porous material, utilizes air or other packing materials of low heat conductivity, reduces building masonry wall thermal conductivity, reduces the conduction of heat via body of wall, reaches the effect of heat-insulation and heat-preservation.Simultaneously, reality use procedure in wall heat insulation material except having outstanding heat insulation effect, in addition it is also necessary to meet following requirement.
1. light: along with the development of urbanization, ratio shared by the middle-high building of city is gradually increased.Light wall heat insulation material is not only advantageous to production and transport, and is conducive to installation, especially the installation process of skyscraper.Conventional inorganic wall heat insulation material is often slightly not enough on light, occurs in that a lot of difficulty in construction and installation process.
2. fire prevention: in recent years, architecture exterior wall insulating materials fire casualty in construction and use procedure appears in the newspapers repeatly.For some organic wall heat insulation material, owing to fire protecting performance is bad, once meet with naked light, it is easy to cause the catching fire building whole body of wall.
The common wall heat insulation material of current China generally can be divided into two kinds, inorganic and organic wall heat insulation material.Inorganic wall heat-insulating material is with rock wool, glass cotton, and thermal insulation mortar etc. is main, is the insulation material grown up at first.The advantage of inorganic heat insulation material is in that it has good fire retardant performance, has good weather-proof, acid and alkali-resistance simultaneously, corrosion-resistant, better with body of wall basic unit binding ability, it is possible to suitable in civilian, industry, the multiple place such as inflammable and explosive, there is the scope of application widely.But, the heat conductivity of inorganic heat insulation material is general higher, and hygroscopicity is big, and freezing tolerance is not enough.Organic wall heat insulation material mainly has polystyrene block, extruded polystyrene board, polyurethane etc., has an advantage in that heat-insulating property is good, it is easy to processing transport, and density is relatively light, easy construction.But its easy catching fire, once occur that naked light is difficult to control, it is easy to cause casualties and property loss.
In recent years, for the problem exposed in current wall heat insulation material use procedure, a collection of Novel wall body heat insulation material is also occurred in that, such as inorganic foamed class, fire-protection modifying class organic insulation material, but high expensive, be not fully solved current wall heat insulation material institute produced problem simultaneously.Such as inorganic foamed class water absorption rate and anti-pressure ability are not enough, and density and insulating power still exist certain distance with organic material.And fire-protection modifying organic material mechanical strength is not enough, easy efflorescence, its fire-retardant being not equivalent to is not fired, and still can be ignited when the intensity of a fire is bigger, and the smog that fire retardant produces is together with the smog of material itself, suffocates easily caused by personnel poisoning after suction.
Due to the desirability of economic development and energy-saving and emission-reduction, wall heat insulation material has market potential widely.Organic wall heat insulation material is simple due to technology maturation, and with low cost, the short time remains without good substitute products and can select.Thus from the prospect of the national conditions of China Yu market, research worker, in conjunction with the advantage of organic inorganic wall heat-insulating material, the shortcoming evading both, is developed a kind of novel fire-proof compound insulation material and will be had far-reaching influence.
Expanded perlite is a kind of inorganic material with loose structure, the structure of hollow porous greatly reduces the density of final products on the one hand, air within hole serves the effect of heat-insulation and heat-preservation on the other hand, reduce the heat conductivity of end article, be a kind of widely used good heat preservation fireproofing material.The advantages such as styrofoam granule is the tailing in benzene plate production process, and its granule has light weight, and heat conductivity is low, has bigger surface area, strong with substrate bonding ability, thus styrofoam is widely used in wall insulation system always.By a certain proportion of interpolation, granular polystyrene can significantly reduce the density of material, improves further the heat-insulating capability of product, and due to the feature of dispersed and distributed in the material, mechanical performance and the fire protecting performance of final products can't be affected, material cost can be reduced simultaneously.Oleic series water-based emulsion is widely used in exterior coating, thermal insulation mortar, in the materials such as polymer mortar, not only there is good weather resistance, water resistance, and there is outstanding adhesive property in the composite, without excess pressure and plastic and possess suitable mechanical strength in the course of processing.Quality is soft simultaneously, and the composite of formation has certain deformability, ensure that when a range of expanding with heat and contract with cold occurs in substrate sheet material is unlikely to crack and crushes.
In the styrofoam occurred in patent documentation before and perlitic composite, as described in CN2767540Y, most all simple with Margarita rock-like material bonding made with styrofoam, this mode has the simple feature of the mode of production, but easily there is the stress concentration that deformation is uneven and causes under external environment condition such as temperature humidity External Force Acting in the faying face of bi-material, the phenomenons such as crack even comes off occurs.And large area uses styrofoam also can reduce the fire protecting performance of material.In CN1092011A, refer to the manufacture method of a kind of many raw materials composite light ash wall body plate, adopt and include perlite and the multiple material of useless benzene plate, but its bonding agent remains as and reclaims inorganic adhesive prepared by waste material, and entirety does not have fire insulation performance.Mentioning a kind of processing technique improving warming plate in CN102491666, wherein key component is expanded perlite, and can contain styrofoam granule in formula, and the bonding agent of its use is still inorganic adhesive, simultaneously the fire prevention feature in not prominent invention.
