Abstract

The invention provides acrylic emulsion for a carpet gum, the carpet gum and a preparation method thereof. The acrylic emulsion for the carpet gum is prepared through a monomer, a buffering agent, anemulsifying agent, a thermal initiator, a reducing agent, water and a pH regulating agent, wherein the solid content of the acrylic emulsion for the carpet gum is 60%, and the viscosity is less than 300cps. The invention also discloses a preparation method of the acrylic emulsion for the carpet gum. The carpet gum is prepared by compositing the acrylic emulsion and Baolija emulsion adhesive for textile. The acrylic emulsion prepared through the abovementioned formula has the active effects of high solid content, high adhering intensity, high repeated separating performance, and water washing and dry cleaning resistance, and can be applicable to carpet gum of various materials.

Description

technical field [0001] The invention relates to the field of carpet back glue, in particular to an acrylic emulsion for carpet back glue, carpet back glue and a preparation method thereof. Background technique [0002] Currently known carpet backings are mostly in the form of hot melt and solvent based rubbers. Hot-melt rubber requires special construction equipment, and has the disadvantages that the viscosity of the product is greatly affected by temperature, it is difficult to handle, and the equipment is not easy to clean. Solvent-based rubber products mostly contain 50% organic solvents. The volatile residues of organic solvents are harmful to the human body and the environment. With the stricter environmental protection policies and the improvement of awareness, solvent-based products will gradually withdraw from the stage of history. [0003] The application publication number is CN105602483A, which discloses a carpet glue containing acrylic components and its prepar...
