Composite door and window grouting mortar and use method thereof

Abstract

The invention discloses a composite door and window grouting mortar and a use method thereof, wherein the composite door and window grouting mortar comprises a powder material and a liquid material, the powder material comprises, by weight, 50-65 parts of cement, 15-25 parts of a mineral admixture, 10-16 parts of a compacting agent, 0.2-0.4 part of an anti-shrinking agent, 3-5 parts of polystyreneparticles, 0.1-0.3 part of cellulose ether, 0.3-0.5 part of a thixotropic agent, 0.2-0.4 part of a water repellent, and 0.05-0.3 part of a water reducing agent, and the liquid material comprises, byweight, 20-35 parts of a polymer emulsion, 0.1-0.5 part of a defoamer, 0.05-0.6 part of a dispersant, 0.03-0.2 part of an antibacterial agent, and 60-70 parts of water. The invention further disclosesa use method of the composite door and window grouting mortar. According to the present invention, the composite door and window grouting mortar has advantages of excellent bonding ability, excellentimpermeability, good reinforcement ability, good anti-deformation ability, shrink cracking resistance, simple use and construction period shortening.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a composite door and window joint-filling mortar and its application method. Background technique [0002] Water leakage from doors and windows of residential buildings has been a relatively common phenomenon for a long time, and it is also one of the most intense problems reported by residential users. Leakage on the wall of the house causes a large area of ​​the wall to peel off, which eventually leads to dampness in the house and a strong musty smell in the room, which not only damages the interior decoration, but also directly affects the physical and mental health of the residents. Not only that, for repairing building leak room, the manpower and material resources and financial resources that people spend for this are quite huge, have disturbed people's work, life, have influenced the service life of whole building. [0003] The selection and quality of caulking...

AI Technical Summary

Problems solved by technology

Polyurethane foam sealant has good adhesion, fast filling construction speed, good elasticity, excellent recovery, and can be suitable for dynamic joints, but polyurethane sealant also has some shortcomings, such as construction quality is not easy to control, foaming agent If the filling is not dense, it will easily cause water leakage. The material itself has poor water resistance, especially alkali water resistance and heat resistance. The storage stability of one-component adhesives is greatly affected by packaging and the outside world. Bubbles and cracks are generated, primer coating is required in many occasions, and the high cost also affects the application of this material

Ordinary cement mortar has a certain flexural and compressive capacity, which is good for window reinforcement, but has poor cohesive force, poor deformation capacity, easy shrinkage and cracking, and easy leakage.
