[0021] 本发明的技术效果是:本发明的喷涂硬泡聚氨酯防水防火保温墙体是复合层结构,在喷涂硬泡聚氨酯防水保温层外,复合了无机轻质骨料水泥砂浆找平抗裂层,由于这种找平抗裂层具有如下优点:其一是找平抗裂层自重轻。 [0021] Technical effects of the invention are: Spray polyurethane foam waterproof fire wall insulation layer of the present invention is a composite structure, in spraying polyurethane foam waterproof insulation layer, the composite inorganic lightweight aggregate cement mortar layer cracking , since this has the advantage that the leveling anti-crack layer: one is light weight anti-crack layer leveling. 在同等批刮厚度的情况下,每公斤无机轻质骨料水泥砂浆的涂布面积是普通抹面砂浆的2倍左右,因此,减小了找平抗裂层与喷涂硬泡聚氨酯防水保温层的竖向剪切力,能克服因聚氨酯保温层表面凹凸不平,找平砂浆用量多使墙体保温和稳定性差的缺点;其二是找平抗裂层裂纹减少。 In the same batch where the thickness of the blade, a coating area per kilogram of an inorganic lightweight aggregate cement is about 2 times the normal surface mortar, thus reducing the leveling and anti-crack layer sprayed polyurethane foam insulation vertical waterproof shearing forces overcome due to uneven surface of the polyurethane insulation, screeds more than the amount that the wall insulation and the disadvantage of poor stability; second leveling reduced anti-crack layer cracks. 本发明的找平抗裂层与喷涂硬泡聚氨酯防水保温层相比,导热系数差距相对较小,减小了因温差引起的裂纹,保证了墙体质量;其三是找平抗裂层具有保温性能。 Leveling anti-crack layer coating of the present invention as compared with waterproof polyurethane foam insulation, thermal conductivity of the gap is relatively small, the temperature difference is reduced due to cracks caused, to ensure the quality of the wall; leveling third is anti-crack layer having insulation properties . 本发明的找平抗裂层导热系数相比普通水泥砂浆找平层低很多,具有保温效果,因此,增强了保温效果;其四是找平抗裂层具有防火性能。 Anti-crack layer leveling thermal conductivity compared to ordinary invention is much lower layer of cement mortar, having a thermal insulation effect, thus enhancing the insulation effect; Fourth leveling anti-crack layer is fire resistant. 由于构成本发明找平抗裂层的无机轻质骨料水泥砂浆具有绝佳的防火性能, 其燃烧性能等级为A级,提高了整个墙体的防火性能,并且对环境也无污染,因此,本发明的找平抗裂层还是环保型的防火层;其五是找平抗裂层具有良好的填充性。 Since the configuration of the present invention, the anti-crack layer leveling inorganic lightweight aggregate cement having excellent fire performance, combustion performance rating of Class A, to improve the performance of the fire wall, and on the environment pollution, therefore, the present leveling anti-crack layer is environmentally friendly fire barrier layer of the invention; Fifth layer is good leveling crack filling. 构成本发明找平抗裂层的无机轻质骨料的粒径《lmm,涂抹过程中无空鼓等现象,一次找平厚度可达5〜lOmm,不仅可以克服喷涂硬泡聚氨酯防水保温层表面凹凸不平所带来的缺点,而且还可以弥补由于现场喷涂硬泡聚氨酯材料无法保证在局部部位如窗口、门口等处完全覆盖的不足,墙体质量提高,施工也更容易;其六是找平抗裂层同时具有抹平、抗裂、保温、防火功能, 不仅简化施工,还可以克服由于批涂多层所出现的各层与硬泡聚氨酯防水保温层之间粘结力差、弹性模量相差大、找平层收縮大、变形协调性不够、易开裂、整个系统防水防火性能差等问题。 Diameter of the inorganic lightweight aggregate of the present invention constituting the anti-crack layer of leveling "lmm, painting process without hollowing phenomenon, a thickness of up leveling 5~lOmm, not only can overcome the surface coating waterproof polyurethane foam insulation uneven disadvantages brought about, but also due to make up for spot spraying polyurethane foam materials can not guarantee local site such as window, door, etc. less than full coverage, improve the quality of the wall construction is also easier; Sixth is leveling layer cracking while having a smooth, crack resistance, thermal insulation, fire safety features not only simplifies the construction, can also overcome the poor adhesion between the layers of waterproof insulation layer and the polyurethane foam because the multilayer coating batch occurring, large difference between the modulus of elasticity, leveling layer shrink large deformation coordination is not enough, easy to crack, the entire system is waterproof and poor fire performance. 因此,本发明的喷涂硬泡聚氨酯防水保温层外,无需外挂经纬线,也无需刨平硬泡聚氨酯保温层,就可以克服喷涂硬泡聚氨酯防水保温层表面凹凸不平所带来的缺点,建成的喷涂硬泡聚氨酯防水防火保温墙体集防水防火保温为一体,易于操作,用料减少,降低了成本。 Thus, the outer coating waterproof polyurethane foam insulation according to the present invention, no plug-in latitude and longitude lines, and without planing polyurethane foam insulation, spray can overcome the disadvantages of the waterproof polyurethane foam insulation caused by the uneven surface, built spray polyurethane foam waterproof fire insulation wall integrally set waterproof fire insulation, ease of operation, reduced use of materials and reduce the cost.
