Abstract

The invention provides an environment-friendly heavy anti-corrosion waterproof material special for a bridge pavement. The environment-friendly heavy anti-corrosion waterproof material special for thebridge pavement is prepared from a main agent I component and an accessory agent P component, wherein a mass ratio of the I component to the P component is 1 to 1; the I component is prepared from the following raw materials: diphenyl-methane-diisocyanate, methylene-bis(4-cyclohexylisocyanate), isophorone diisocyanate, 2,2,4-trimethylhexamethylene diisocyanate, polyether polyol and epoxy resin; the P component is prepared from the following raw materials: an amine cross-linking chain extender, polycarbonate polyol, polycaprolactone polyol, polytetrahydrofuran polyol, a plasticizer, zinc oxide, sericite powder, precipitated barium sulphate, pigment and filler, an active nano compound alloy factor, a catalyst and an auxiliary. After the anti-corrosion waterproof material is applied to the bridge pavement, the comprehensive pavement performance of the bridge pavement is greatly improved, the service life of a road is prolonged, and corrosion and leakage caused by an external environmentare prevented.

Description

technical field [0001] The invention belongs to the technical field of anti-corrosion materials, and in particular relates to an environment-friendly special heavy-duty anti-corrosion and waterproof material for bridge pavement and a preparation method thereof. Background technique [0002] Today's bridge projects not only require a large investment, but also have a long design life, and are located in critical parts of traffic, so the safety and durability of bridges are very important. In the past, we have not paid much attention to the anti-corrosion and waterproofing of the base of bridge projects, resulting in serious corrosion and leakage problems during the commissioning of most bridge bases and their ancillary facilities. With the rapid development of the economy, a considerable scale of reinforced concrete bridges was built after the 1980s, especially with the construction of expressways, the standards of bridges have been rapidly improved. The seriousness and impo...
