Embodiment Construction

[0013] The invention discloses a thermal insulation elastic sealant. The thermal insulation sealant is a special sealant for thermal insulation external walls, and is composed of materials according to the following weight ratio:

[0014] 20-40 parts of vitrified microbeads;

[0015] 20-40 parts of acrylate synthetic resin;

[0016] 20-30 parts of polypropylene staple fiber;

[0017] 5-10 parts of mica powder.

[0018] Among them, vitrified microbeads are a kind of acidic vitreous lava minerals (turpentine ore). After special technical treatment and production process, they form internally porous, surface vitrified and closed, and are spherical fine-diameter particles. A new type of inorganic lightweight thermal insulation material with high performance. Due to the surface vitrification to form a certain particle strength, the physical and chemical properties are very stable, the aging resistance and weather resistance are strong, and it has excellent heat insulation, fire ...

Abstract

The invention discloses a heat preservation, heat insulation and elastic grout joint filling. The grout joint filling comprises the following components in weight portion: 20 to 40 portions of vitrified micro bubble, 20 to 40 portions of acrylic ester synthetic resin, 20 to 30 portions of polypropylene short fiber and 5 to 10 portions of mica powder. The coefficient of heat conductivity(W / (mk)) of the grout joint filling is less than or equal to 0.07, and the elastic stretch modulus(MPa(23 DEG C,,20 DEG C below zero)) is more than 0.4 or more than 0.6, so that the grout joint filling has the advantages that besides the characteristics of endurance, water resistance, pressure resistance and the like which are possessed by the common ceramic wall floor tile grout joint filling, the grout joint filling of the invention also has the effects of heat preservation and heat insulation, and the functions of a certain elastic stretch modulus, fire resistance and sound insulation.

Description

technical field [0001] The invention relates to a caulking agent, in particular to a special caulking agent for thermal insulation external walls. Background technique [0002] After pasting tiles on the exterior walls of buildings, the gaps between the tiles need to be filled. In the past, white cement was used to inlay them. Sometimes, in order to match the color of the tiles, the construction workers themselves would mix some paint inside. In fact, there are many disadvantages of filling in this way. For example, it will become moldy in humid seasons. If you wipe it, you will definitely not be able to clean it thoroughly. Moreover, the cement will easily crack, fall off, and seep water after a short time. It is neither aesthetically pleasing nor hygienic nor durable. Its advantage is low price, but the disadvantages of white cement are uneven particle size, easy efflorescence, easy cracking, easy falling off, easy weathering, easy dirty, difficult to clean, and single co...
