[0059] Preparation and optimization of stabilizer solutions

[0060] The stabilizer is the modified asphalt stabilizer produced by Dongying Runfeng Boyue Petroleum Technology Co., Ltd.

[0061] Preparation: After heating the base oil or asphalt to 140°C, add the stabilizer, the stirring speed is fixed (the speed of the stirring paddle in the laboratory is 300r / min), and observe whether the additive has climbing rod phenomenon (that is, the viscosity), the degree of melting of the stabilizer ( Whether it is completely dissolved), and whether there is precipitation.

[0062] Option 1: Use 90# asphalt to dissolve the stabilizer, tentatively asphalt:stabilizer is 5:1;

[0063] raw material name Raw material model Proportion / % asphalt 90# 50 stabilizer / 10

[0064] Experimental phenomenon: when the asphalt is heated to the set temperature and the stabilizer is added, the viscosity of the rubber material increases dramatically instantly, and the sti...

example 1

[0077] Taking the PET product of GB / T35467-2017 as an example, its base film is a transparent silicone oil film; compared with PET aluminum-coated silicone oil film and PE black film, the surface temperature of the product is the highest under the same sunshine conditions. Constant—The formula remains unchanged, and different proportions of stabilizers are added to it to test various properties.

[0078] This example provides the original GB / T35467-2017 PET product formula, which is made by mixing liquid material, powder material and granular material, and the weight percentages are as follows:

[0079] Table 1

[0080]

[0081] The asphalt compound preparation process comprises the following steps:

[0082] S1. Add asphalt and oil, heat up to 120±5°C, add SBS and sol 0506, control the temperature at 180±5°C, and stir for 100-140 minutes;

[0083] S2. Add SBR, stir for 20-40 minutes, then add rubber powder, stir for 50-70 minutes;

[0084] S3. Add modified petroleum resi...

[0095] The asphalt compound preparation process of the coil comprises the following steps:

[0096] S1. Add asphalt and oil, heat up to 120±5°C, add SBS and sol 0506, control the temperature at 180±5°C, and stir for 100-140 minutes;

[0097] S2. Add SBR, stir for 20-40 minutes, then add rubber powder, stir for 50-70 minutes;

[0098] S3. Add modified petroleum resin and stabilizer solution, control the temperature at 180±5°C, and stir for 80-100 minutes to obtain a mixed solution; add stone powder after the mixed solution is ground, stir for 20-40 minutes, control the temperature at 155±5°C and discharge .

Abstract

The invention provides application of a stabilizer for improving the film tearing performance of a tire-free waterproof coiled material, the stabilizer is dissolved in an oil product to form a stabilizer solution, and the mass ratio of the stabilizer to the oil product is 1: (3-5); the stabilizer solution is placed in an independent tank body and is slowly injected when an asphalt sizing material of the tire-free waterproof roll is prepared, and the dosage of the stabilizer is 0.05-0.10% of the total weight of the asphalt sizing material. The adding mode and the adding amount of the stabilizer are optimized, firstly, the stabilizer is pre-dissolved with an oil product, the stabilizer is uniformly dispersed in the oil product to obtain the stabilizer solution, and then the stabilizer solution is slowly injected when the asphalt sizing material of the tire-free waterproof coiled material is prepared. By adding the stabilizer, the cohesion of the modified asphalt sizing material is improved, the penetration of the asphalt sizing material is reduced, the cohesion degree of the asphalt sizing material is improved, the film tearing effect of the tire-free coiled material at high temperature is improved, and the construction applicability is solved.

Description

technical field [0001] The invention belongs to the technical field of waterproof coiled materials, and in particular relates to the application of a stabilizer for improving the tearing performance of tireless waterproof coiled materials. Background technique [0002] Waterproof roll material is mainly used in building walls, roofs, tunnels, roads, landfills, etc., to resist external rainwater and groundwater leakage, a flexible building material product that can be rolled into rolls, as an engineering foundation and building There is no leakage connection between objects, which is the first barrier for waterproofing of the whole project and plays a vital role in the whole project. The performances of the existing waterproof membranes on the market meet the standard requirements, but the surface temperature of tireless waterproof membranes can reach above 55°C when exposed to direct sunlight in high temperature weather in summer. inconvenient. The reason for this phenomen...
