Problems solved by technology

These halogen elements are extremely harmful to the environment and do not meet environmental protection requirements.
However, when the common halogen-free flame retardant products are mixed with the rest of the hot melt adhesive, it will affect the conventional performance of the hot melt adhesive itself.

Abstract

The invention discloses a flame-retardant hot melt adhesive and a preparation method thereof. The hot melt adhesive is prepared from the following raw materials: first petroleum resin, second petroleum resin, Fischer-Tropsch wax, a polyolefin toughening agent, an antioxidant and a flame retardant, wherein the flame retardant is one or a composition of two of aluminum hydroxide, magnesium hydroxide and an MCA flame retardant. The polyolefin toughened resin, the two petroleum resins, the Fischer-Tropsch wax, the antioxidant and the specific powder flame retardant are combined, so that the hot melt adhesive has good flame retardance, cohesiveness and thermal stability. According to the preparation method disclosed by the invention, after the Fischer-Tropsch wax, the antioxidant and the flame retardant are uniformly mixed, the other resin materials are added, so that the problems of non-uniform mixing and incomplete dispersion of the powder flame retardant and the hot melt adhesive matrix resin particles are avoided, the dispersion uniformity is good, the subsequent granulation operation is convenient, and the production cost is reduced. Therefore, the flame retardance, cohesiveness and thermal stability of the hot melt adhesive are improved.

Description

technical field [0001] The invention relates to the technical field of hot-melt adhesives, in particular to a flame-retardant hot-melt adhesive and a preparation method thereof. Background technique [0002] Hot melt adhesive is solid at room temperature, and can be applied to the adherend after melting at low temperature. After pressing and cooling, the bonding process can be completed in a short time. Due to the outstanding advantages of environmental protection, safety, rapid curing and suitable for automatic production, hot melt adhesives have developed rapidly in the past ten years. Worldwide, hot melt adhesives have become the third largest variety with the fastest growth and the most development potential after polymer emulsions and traditional solvent-based adhesives. [0003] Flame-retardant protective clothing refers to a protective clothing that can slow down the spread of flames and carbonize to form an isolation layer to protect human safety and health when it...
