Construction method for bonding pearlite insulation board

Abstract

The invention discloses a construction method for bonding a pearlite insulation board. According to the characteristics of pearlite insulation board materials, a magnesium-based adhesive is prepared.Through polymer modification, magnesium-based inorganic adhesive crystals form an organic-inorganic interpenetrating network structure, and a certain bridging role is played, so that the bonding strength of the materials is increased. At the same time, emulsion solidifies into a film, the pores in perlite of the insulation board are blocked, hole walls are connected, the fit degree between the adhesive and the perlite insulation board is enhanced, and the stability of the insulation board after bonding is ensured. At the same time, an integral and tight operation mode is adopted aiming at slabjoints and door and window holes, gaps between slabs are reduced, and the phenomenon of swelling and slab warping is avoided. Compared with traditional insulation mortar, the smoothness is higher, and the construction is convenient. The application of the adhesive increases the bonding fastness and reliability of the insulation board, prevents the shedding and prolongs the service life, and thengood insulation and energy saving effects are achieved.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a construction method for pasting perlite insulation boards. Background technique [0002] As people pay more and more attention to building energy conservation and environmental protection, building insulation technology develops rapidly. The commonly used thermal insulation mortar is difficult to guarantee product quality due to the backward equipment and technology of the production enterprises and the gradual improvement of national building energy-saving standards. At the same time, it is greatly restricted by the ambient temperature and weather during construction. ensure. [0003] At present, based on the design requirements of building energy conservation and environmental protection, the insulation layer is generally installed on the outer wall of the building. To ensure the bonding of the insulation layer and the wall, it is mainly realized by gluing b...

Problems solved by technology

According to the construction specifications, the bonding area between the insulation board and the wall needs to reach 50% to meet the requirements of the bonding strength. However, in actual bonding construction, glue is usually placed on the back of the insulation board for bonding, so it is often impossible to meet the requirements for the bonding area. The insulation board is easy to fall off after being blown by wind, rain, and sun, and there are serious safety hazards
