Abstract

The invention discloses a reaction type waterproof bonding material and a production technology thereof. The production technology comprises the steps: pouring butyl acetate, dipropylene glycol monomethyl ether and alkyl methacrylate esters into a reaction kettle, uniformly mixing thermoplastic styrene-butadiene rubber SBS411, butadiene-styrene rubber SBR1502 and stearic acid in a double-roller rubber mixing mill to obtain a mixture, adding the mixture into the reaction kettle, adding c-9 petroleum resin into the reaction kettle, sealing the reaction kettle, performing heating while stirring, opening the reaction kettle after cooling, adding kieselguhr and liaohe #90 matrix asphalt, performing heating and stirring, discharging a material, then adding a furfural acetone resin prepolymer and an active initiator, and uniformly mixing to obtain the reaction type waterproof bonding material. The production technology has the advantages that the preparation technology is simple, the content of volatile matters is low, a composite system is high in stability, the later reaction bonding performance is excellent, and the reaction type waterproof bonding material is an irreplaceable material for converting a white cement pavement into a black cement pavement and preventing corrosion to a cement bridge deck.

Description

technical field [0001] The invention relates to a reactive waterproof adhesive material and a production process thereof. technical background [0002] Cement concrete pavement is a low-end economical road, but the economy, comfort and low noise of cement pavement are far inferior to asphalt concrete pavement. In underdeveloped areas of my country, many urban traffic roads are still cement concrete. When cement concrete is upgraded to asphalt concrete, the bonding between asphalt concrete and cement concrete becomes the primary problem. If the bonding problem is not handled properly, the road surface is prone to slippage, stacking and cracks. There are also some overpasses and interchange bridges with cement concrete structures, and asphalt concrete on the surface also needs bonding materials. The use of this bonding material is to change white to black for cement concrete. [0003] CN 101407387B discloses a second-order reaction type waterproof bonding material, which has ...
