Abstract

The invention relates to the technical field of novel functional materials, and discloses a waterproof and anti-cracking gel material for buildings. The gel material is synthesized and prepared by taking asphalt as a base material, and a chemical bond is formed through a toughening modifier and asphalt polymers to form a firm adhesion and interlocking structure, so that the interaction between asphalt molecules is strengthened, the cohesion is improved, the waterproof, anti-cracking and temperature resisting properties are successfully improved, the problem that the conventional waterproof base material has obvious elastic effect and bad temperature resistance and are easy to be influenced by environment factors such as temperature and the like so as to deform is solved, the stability andcohesiveness are good, the temperature resistance is improved, the service life of the waterproof material is remarkably prolonged, the mechanical properties such as tensile strength, tear resistanceand flexural strength of the material are significantly improved when being compared with the existing level, and the appearance and physical mechanical properties of the waterproof layer are guaranteed for a long time.

Description

technical field [0001] The invention belongs to the technical field of new functional materials, and in particular relates to a waterproof and anti-crack gel material for construction. Background technique [0002] The waterproof material is the building envelope to prevent the penetration of rainwater, snow water and groundwater; to prevent the erosion of moisture, steam and other harmful gases and liquids in the air; the separation structure to prevent the seepage of water supply and drainage. These materials that prevent penetration, leakage and erosion are collectively referred to. Materials that prevent rainwater, groundwater, industrial and civil water supply and drainage, corrosive liquids, and moisture and steam in the air from intruding into buildings. The parts of buildings that need to be waterproofed are mainly roofs, walls, floors and basements. There are many kinds of waterproof materials, which can be divided into 4 categories according to their main raw mat...
