Problems solved by technology

[0003] The foaming hot-melt adhesives in the prior art have poor foaming effect when used, and do not have the function of flame retardancy. When stored, they need relatively harsh storage conditions, and long-term storage will shorten the service life. , easy to oxidize, so that the colloid deteriorates; at the same time, in the process of making the foamed hot melt adhesive in the prior art, when the raw material is pulverized, the pulverization effect is poor, so that the particle size of the raw material is large, resulting in when heated, Incomplete melting of raw materials affects the bonding quality of colloids. Therefore, it is necessary to design a foaming hot melt adhesive and its production process.

Abstract

The invention discloses a foaming hot melt adhesive and a preparation process thereof. The foaming hot melt adhesive comprises 40-60% of APAO random poly-alpha olefin, 1-12% of polyethylene wax, 0.1-1% of an antioxidant, 30-45% of a C5 petroleum resin, 2-5% of a foaming agent and 3-6% of a flame retardant. According to the invention, by selecting the APAO random poly-alpha olefin, the polyethylenewax, the antioxidant, the C5 petroleum resin, the foaming agent and the flame retardant as raw materials, the prepared foaming hot melt adhesive is convenient to store, long in service life and goodin foaming effect and has a certain flame retardant effect; and in the manufacturing process, the polyethylene wax and the C5 petroleum resin are deeply embrittled through liquid nitrogen so as to effectively improve the crushing effect of the polyethylene wax and the C5 petroleum resin, so that the melting effect among the raw materials can be improved during heating, and the bonding strength ofthe foaming hot melt adhesive is greatly improved.

Description

technical field [0001] The invention relates to the technical field of hot-melt adhesives, in particular to a foaming hot-melt adhesive and a manufacturing process. Background technique [0002] Foaming hot-melt adhesive is a kind of hot-melt adhesive; when the hot-melt adhesive is heated and melted, a special foaming glue applicator machine is used to make the glue foam immediately after mixing and coating, or use a chemical decomposition reaction to make it The adhesive layer contains air bubbles; foaming hot melt adhesive prevents deformation of heat-sensitive materials and seals parts with large gaps. [0003] The foaming hot-melt adhesives in the prior art have poor foaming effect when used, and do not have the function of flame retardancy. When storing, they need relatively harsh storage conditions, and long-term storage will shorten the service life. , easy to oxidize, so that the colloid deteriorates; at the same time, in the process of making the foamed hot melt ad...
