Abstract

The invention relates to a seam binding agent with modified fatty amine as epoxy curing agent resin. The agent is suitable for easy-cracking positions in indoor and outdoor decorations. The agent is filled into seams of same or different materials such as wood, brick and stone, gypsum board, calcium silicate, and the like, for providing an excellent anti-cracking effect. The agent can also be used as a binding agent for roof leakage repairing, wood, and plastic. The agent can be used in crack sealing and water proofing of various grouting projects, bridges, and tunnels. According to the invention, a novel nano fiber binding technology is adopted. When the product is cured, nano fibers in the product form a high-molecular high-density net-shaped film at a seam position, wherein the physical density of the film is close to that of wood board or gypsum board. The film can expand or contract synchronically with the board when weather is changed, and has good cracking resistance, adhesive force, and flexibility. The seam binding agent is advantaged in fast shaping, easy construction, and low sagging.

Description

【Technical field】 [0001] The invention relates to a coating auxiliary material, in particular to an epoxy series auxiliary material using modified fatty amine as an epoxy resin curing agent. 【Background technique】 [0002] Joint compound is a kind of paint, which is a kind of coating product when decorating objects. As the name suggests, the joint agent is a new type of coating that connects the gaps between objects. The joint agent has strong crack resistance and adhesion, flexibility, strong wear resistance, good water resistance, corrosion resistance, yellowing resistance, color impermeability, It is safe and environmentally friendly, and has excellent accumulation performance, simple construction, and can be quickly shaped after a moderate drying time. It can be dried within 2 hours at room temperature at 20-25°C, and hard-dried for 24 hours. It will reach the best hardness in three days. After drying, a high-density, high-strength mesh coating is formed on the seams. ...
