Problems solved by technology

[0002] At present, the SBS modified asphalt waterproofing membrane on the market has a limited degree of adhesion to the self-adhesive modified asphalt waterproofing membrane, and construction requires high temperature and open fire to heat up, so there are potential safety hazards
At present, during the construction of oily non-curing waterproofing on the market, high-temperature spraying construction personnel often get burned, and the water-based non-curing construction period is long, and the effect is not as good as oily.
There are also some butyl tape cost issues that cannot meet large-scale waterproofing projects

specific Embodiment

[0024] 1. Preparation of blended asphalt

example 1

[0025] Example 1 Mix 20 kg of 90# asphalt with 80 kg of 70# asphalt to form 100 kg of blended asphalt;

[0026] Example 2 Take 25 kilograms of 90# asphalt and 75 kilograms of 70# asphalt and mix it into 100 kilograms of blended asphalt;

[0027] Example 3 Take 40 kg of 90# asphalt and 60 kg of 70# asphalt and mix it into 100 kg of blended asphalt;

[0028] Among them, 90# asphalt and 70# asphalt are both grade A road petroleum asphalt.

[0029] 2. Preparation of rubber powder

[0030] Example 1 Get 100 kilograms of 60 mesh desulfurized rubber powder and 90 kilograms of 40 mesh rubber powder and mix them into 190 kilograms of rubber powder;

[0031] Example 2 Get 100 kilograms of 60 mesh desulfurized rubber powder and 100 kilograms of 40 mesh rubber powder and mix them into 200 kilograms of rubber powder;

example 3

[0032] Example 3 Take 100 kg of 60-mesh desulfurized rubber powder and 110 kg of 40-mesh rubber powder and mix them into 210 kg of rubber powder.

[0033] 3. Preparation of high temperature modifier

[0034] Example 1 Take 100 kg of BL polyhydroxymagnesium stearate H-35 and 90 kg of ZCR temperature control agent and mix them into 190 kg of high temperature modifier;

Abstract

The invention relates to the technical field of waterproof materials, particularly discloses a thixotropic modified asphalt waterproof coiled material, and provides a preparation method thereof. The waterproof coiled material comprises a creep rubber asphalt sizing material layer and isolating membranes attached to the two surfaces of the creep rubber asphalt sizing material layer, wherein the creep rubber asphalt sizing material layer comprises the following components in parts by weight: 40-60 parts of blended asphalt, 10-20 parts of a reinforcing agent, 5-10 parts of rubber powder; 2-6 parts of a high-temperature modifier; 10 to 30 parts of a softening agent; 5-10 parts of a high-molecular polymer; and 10-20 parts of filler. The problems that a waterproof roll is poor in stress resistance, prone to cracking after long-term use and short in service life are effectively solved. The waterproof coating has the characteristics of simple production process, convenience in construction, excellent weather resistance and the like, and can be widely applied to waterproofing of various basal planes.

Description

technical field [0001] The invention relates to the technical field of waterproof materials, in particular to a touch-adhesive modified asphalt waterproof membrane, and provides a preparation method thereof. Background technique [0002] At present, the SBS modified asphalt waterproofing membrane on the market has a limited degree of adhesion to the self-adhesive modified asphalt waterproofing membrane, and construction requires high temperature and open fire to heat up, so there are potential safety hazards. At present, during the construction of oily non-curing waterproofing on the market, high-temperature spraying workers often get burned, and the water-based non-curing construction period is long, and the effect is not as good as oily. There are also some butyl tape cost issues that cannot meet large-scale waterproofing projects. Contents of the invention [0003] In order to make up for the defects of the prior art, the present invention provides a modified asphalt w...
