Abstract

The invention belongs to the technical field of functional building coatings, and relates to a fire-proof thermal isolation heat preservation putty and a preparation method thereof. The fire-proof thermal isolation heat preservation putty is prepared from the following raw materials in parts by weight: 2-10 parts of nanometer composite aerogel, 15-45 parts of hollow glass microsphere, 1-10 parts of glass bead, 3-15 parts of cement, 0.1-1 part of cellulose, 0.1-0.5 part of polypropylene fiber, 10-30 parts of water-based silicon resin emulsion, 0.1-1 part of dispersant and 0.1-1 part of wettingagent. The fire-proof thermal isolation heat preservation putty provided by the invention combines reflection, thermal isolation, radiation and fire prevention into a whole, infrared light and visiblelight can be reflected, the fire-proof thermal isolation heat preservation putty has a better thermal isolation heat preservation effect, the efficacy of warmness in winter and coolness in summer, energy saving, consumption reduction, fire prevention and the like can be realized, and in addition, the fire-proof thermal isolation heat preservation putty has high tensile strength and compressive strength.

Description

technical field [0001] The invention belongs to the technical field of functional architectural coatings, and relates to a fireproof heat-insulating putty and a preparation method thereof. Background technique [0002] Nowadays, the thermal insulation technology of building exterior walls is developing rapidly, which has played a great role in promoting the construction industry. However, the capacity of the traditional building exterior insulation system is large, which increases the weight of the entire building. Therefore, the application of thermal insulation coatings to the building exterior insulation system can greatly reduce the load of the building insulation system. [0003] On the other hand, fireproof materials are needed outside the exterior walls of buildings, and water-based fireproof adhesives can block flames to form carbon expansion bodies, and they are low-smoke, non-toxic, and translucent, so they have excellent fireproof performance and physical properti...
