Abstract

The invention relates to a preparation method of a hot-melt pressure-sensitive adhesive for a high-density polyethylene self-adhesion coiled material. The preparation method comprises the following steps of: compounding another styrene diene styrene block copolymer (SDS) synthetic rubber by using an SDS rubber elastomer as a main matrix resin to modify an elastomer; and mixing with proper sticky resin, softening agents, antioxidant and the like to prepare the hot-melt pressure-sensitive adhesive. The characteristics of SDS synthetic rubber elastomers with two different molecule structures are fully utilized, and the problems of elasticity, room-temperature construction and high-temperature resistant adhesiveness are successfully solved, so that a product which is easy to process, compatible with various materials, and high in transparency, chemical resistance, long-term ageing resistance, high wettability of high-density polyethylene (HDPE) substrates and high in adhesion is obtained.

Description

technical field [0001] The invention belongs to the field of chemical industry and relates to a method for preparing a hot-melt pressure-sensitive adhesive, in particular to a method for preparing a hot-melt pressure-sensitive adhesive for high-density polyethylene self-adhesive coils. Background technique [0002] High-density polyethylene (HDPE) self-adhesive film waterproof membrane and its pre-paved anti-adhesive construction technology were introduced into my country by American companies in the 1990s, and model laying was carried out in tunnels dug in underground subway intervals. In November 2008 and March 2009, the state issued relevant standards to vigorously promote the application of pre-paved construction technology and self-adhesive waterproof membrane materials. [0003] Since polyethylene is a non-polar material with low surface energy, it is a difficult-to-stick material. Hot-melt pressure-sensitive adhesives used to bond polyethylene materials must have a s...
