Abstract

The invention relates to a non-yellowing polyurethane two-component adhesive, which is particularly suitable for bonding stones of permeable pavements of sponge cities and slow walks of cities and bonding various recyclable solid waste aggregates, and belongs to the technical field of adhesives for pavements. Comprising a component A and a component B in a weight ratio of 100: (50-80), the component A comprises the following raw materials in parts by weight: 90-100 parts of amino-terminated polyether, 0-3 parts of a stabilizer, 0-3 parts of a water removal agent and 0-2 parts of a defoaming agent; the component B is prepared from the following raw materials in parts by weight: 70 to 100 parts of aliphatic isocyanate and 0 to 30 parts of modified aliphatic isocyanate. Under the condition that the rigidity is met, yellowing cannot be generated.

Description

technical field [0001] The invention relates to a non-yellowing polyurethane two-component adhesive, which is especially suitable for the bonding of stones on permeable pavements and urban slow-moving roads in sponge cities, as well as the bonding of various recyclable solid waste aggregates. Adhesive technology field. Background technique [0002] At present, urban surfaces are increasingly covered with "hardened" materials such as asphalt and cement concrete. Although the hardened pavement of asphalt and cement concrete brings convenience to people's life and travel, it also brings a series of problems that plague people, such as urban waterlogging, noise pollution, "heat island effect", slippery and icing, etc. In response to the environmental problems brought about by the development of urbanization, corresponding governance measures have been introduced in China. [0003] "Sponge city" refers to a city that, like a sponge, has good "elasticity" in adapting to enviro...
