Problems solved by technology

[0003] However, the existing hot melt adhesives need to add 10-20% naphthenic oil to adjust the viscosity of the colloid, but the plasticizer will be precipitated from the sheet and the performance of the colloid will be greatly reduced; and the high temperature performance is poor, and it is prone to aging, resulting in rotten glue and oil leakage. , affecting the service life of the floor

Abstract

The invention is applicable to the technical field of polymer glue, and provides a high-temperature-resistant and plasticizer-resistant hot melt adhesive, and a preparation method and application thereof. The high-temperature-resistant and plasticizer-resistant hot melt adhesive is prepared from, by mass, 40-45% of rubber, 35-45% of tackifying resin, 9-15% of polyisobutene, 3-7% of powder, 1-3% of an antioxidant, and the balance of hydrogenated DCPD resin. The hot melt adhesive disclosed by the invention has the advantages of high temperature resistance, aging resistance, good plate plasticizer resistance, high bonding strength and the like; the naphthenic oil is not added, the viscosity can be effectively reduced by optimizing the variety and dosage of the raw materials, and the anti-plasticizer performance is obviously improved; and the adhesive can be used as a back adhesive for a self-adhesive floor, and the phenomena of adhesive rotting, adhesive overflowing, viscosity loss and oil leakage are avoided.

Description

technical field [0001] The invention belongs to the technical field of polymer glue, and in particular relates to a hot-melt adhesive with high temperature resistance and plasticizer resistance, a preparation method and an application. Background technique [0002] Hot melt adhesives can be applied to self-adhesive flooring, which has obvious advantages over earlier construction adhesives for flooring. Early floors were constructed with acrylic pressure-sensitive adhesive, but the technical defect is that the builder must purchase glue separately, apply it on the ground during construction, and stick the floor after the glue is completely dry, which is relatively inconvenient and time-consuming. Hot melt adhesive can be directly coated on the back and covered with release paper for protection during floor production. It can be directly paved on the floor during construction. The construction is simple and the operation is convenient. [0003] However, the existing hot melt ...
