Problems solved by technology

When using cement mortar for caulking, the moisture in the mortar is easily absorbed by the surface of the board quickly, causing the caulking mortar to have no strength or become powdery, cracks are prone to occur at the joints of the boards, and the joints of the boards are not tightly connected, which affects the use of the boards performance

Abstract

The invention discloses an environment-friendly autoclaved aerated concrete panel caulking agent, which is prepared from the following components in parts by weight: 5-30 parts of a building adhesive,10-40 parts of heavy calcium carbonate, 30-50 parts of sand, 5-15 parts of water, 0.5-2 parts of a waterproof agent, 0.1-0.5 part of polypropylene fibers, 0.3-1 part of a water-retaining agent, 0.1-0.5 part of an antifreezing agent, 0.3-1 part of a defoaming agent, 0.5-1 part of a fire retardant and 0.5-1.5 parts of a preservative. Due to the synergistic effect of all the components, the environment-friendly autoclaved aerated concrete panel caulking agent has better cohesiveness and flexibility, can overcome the water absorption property of autoclaved aerated concrete panels, enables the panels to be better connected with each other, and reduces the permeation of erosive substances such as water so as to enable the panels not to crack in a using process and prolong the service life of awall body; the caulking agent can be directly used for field construction without being stirred, thus reducing the flying dust during field construction and having environmental friendliness.

Description

technical field [0001] The invention relates to a caulking agent, in particular to an environment-friendly autoclaved aerated concrete board caulking agent. Background technique [0002] Aerated concrete is widely used because of its advantages of light weight, porous, sound insulation, thermal insulation, and good fire resistance, and it is a new type of wall material. According to the structural requirements and its own deformation characteristics during installation, a certain number of expansion and contraction joints need to be set, and installation joints will also be formed when the panels are spliced. After the installation is completed, the formed plate seams need to be jointed. When using cement mortar for caulking, the moisture in the mortar is easily absorbed by the surface of the board quickly, causing the caulking mortar to have no strength or become powdery, cracks are prone to occur at the joints of the boards, and the joints of the boards are not tightly co...
