Problems solved by technology

However, the price of polymethylethoxysilane raw materials is relatively high, resulting in a product price that is not close to the people. The price of the product obtained by using polynaphthalene sulfonic acid sodium salt has certain advantages, but it will decompose slowly during use, resulting in harmful substances such as formaldehyde.

Embodiment 1

[0015] Add 40 parts of No. 70 petroleum asphalt into the reaction kettle, add 8 parts of SBS rubber modifier, raise the temperature to 110-115°C, stir for 30 minutes, then raise the temperature to 180-185°C, continue stirring for 1 hour, add 0.5 parts of aluminum zirconium acid Ester waterproof bridging agent, stir for 30 minutes, cool down to 120-130°C to get reactive modified asphalt, apply it on non-woven fabric to make waterproof membrane.

Embodiment 2

[0017] Add 60 parts of No. 90 petroleum asphalt into the reaction kettle, add 12 parts of SBR rubber modifier, raise the temperature to 115-120°C, stir for 30min, then raise the temperature to 185-190°C, continue stirring for 1.5h, add 2 parts of chlorinated Trioctyltin, stirred for 30 minutes, cooled to 120-130°C to obtain reactive modified asphalt, which was applied on non-woven fabric to make waterproof membrane.

Embodiment 3

[0019] Add 66 parts of No. 90 petroleum asphalt into the reaction kettle, add 4 parts of SBS rubber modifier and 12 parts of SBR rubber modifier, raise the temperature to 115-120°C, stir for 30min, then raise the temperature to 185-190°C, and continue the stirring reaction After 1.5 hours, add 3 parts of di-n-butyl ethyl phosphate, stir for 30 minutes, and cool down to 120-130°C to obtain reactive modified asphalt, which can be applied to non-woven fabrics to make waterproof membranes.

Abstract

The present invention aims to provide reactive type modified asphalt and a production method therefor, and particularly relates to reactive viscosity modified asphalt that can perform chemical cross-linking and physical tenon connection with concrete. The reactive type viscosity modified asphalt is prepared by raw materials comprising asphalt, a rubber modifier, and a waterproof bridging agent. The modified asphalt provided by the present invention can be used as an adhesive layer of a waterproof roll or directly used as a waterproof material to build a waterproof bridge, and generates very strong adhesion force with a cement base surface.

Description

technical field [0001] The invention relates to a reactive modified asphalt, which is a modified asphalt capable of chemically reacting with cement concrete to produce chemical crosslinking and physical mortise and tenon effects, and discloses a production method of the modified asphalt. Background technique [0002] Modified asphalt is to add rubber, resin, high molecular polymer, ground rubber powder or other fillers and other external additives (modifiers) to asphalt, or take measures such as mild oxidation of asphalt to make asphalt low temperature It is not easy to be brittle, and it is not easy to flow at high temperature. There are two mechanisms for modifying asphalt, one is to change the chemical composition of asphalt, and the other is to make the modifier evenly distributed in the asphalt to form a certain spatial network structure. The modified asphalt currently on the market mainly includes: 1. Rubber and thermoplastic elastomer modified asphalt: including: nat...
