Problems solved by technology

Generally, it is necessary to use a base treatment agent on the base layer for pretreatment during construction, but even with pretreatment, there is no guarantee that the self-adhesive waterproof membrane can be effectively bonded to the base layer. The resulting hollowing phenomenon leads to the hidden danger of water channeling between the base layer and the waterproof membrane

Embodiment 1

[0040] A self-adhesive waterproof coiled material supporting adhesive for construction in low temperature environment, its formula is as follows:

[0041] 20kg of petroleum asphalt marked 70#, 40kg of ethyl acetate, 5kg of butyl acetate, 10kg of styrene-butadiene rubber YH-503T, 10kg of C5 resin;

[0042] Prepare as follows:

[0043] First weigh the raw materials according to the above formula, put ethyl acetate and butyl acetate into the reaction kettle, and mix them evenly at a stirring rate of 1000rpm to obtain a composite diluent; then add styrene-butadiene rubber into the compound diluent, Stir for 3 hours, then add C5 resin, and stir for 4 hours at a stirring rate of 1000rpm to obtain a mixture; finally, add petroleum asphalt to the mixture and stir for 6 hours at a stirring rate of 3000rpm to obtain a self-adhesive waterproofing membrane low-temperature construction supporting adhesive.

Embodiment 2-12

[0045]A self-adhesive waterproof coiled material construction adhesive in low temperature environment, the difference from Example 1 lies in the composition of raw materials, the specific composition is shown in Table 2 below.

[0046] Table 2. Composition of raw materials

[0047]

[0048] Note: 1. The block ratio of SIS is S / I=15 / 85;

[0049] Nano montmorillonite is mixed into petroleum asphalt together with petroleum asphalt.

Embodiment 13

[0051] A self-adhesive waterproofing coiled material supporting adhesive for construction in low temperature environment, the difference from Example 12 is that the label of petroleum asphalt is different, and the label of petroleum asphalt in Example 13 is 90#.

Abstract

The invention relates to a building material, and particularly discloses a self-adhesive waterproof roll low-temperature environment construction matching adhesive. The invention relates to a self-adhesive waterproof roll low-temperature environment construction matching adhesive which is prepared from the following raw materials in parts by weight: 20-30 parts of petroleum asphalt, 45-65 parts of a composite diluent, 10-20 parts of thermoplastic rubber and 10-20 parts of tackifying resin; and the composite diluent is prepared by compounding a quick-drying diluent with a boiling point of 60-80 DEG C and a slow-drying diluent with a boiling point of 120-130 DEG C according to a weight ratio of (40-50): (5-15). The prepared self-adhesive waterproof roll low-temperature environment construction matching adhesive has good construction performance at low temperature, the initial adhesion performance is good after low-temperature curing, toughness is good, bubbling and other phenomena are not prone to occurring, and the self-adhesive waterproof roll low-temperature environment construction matching adhesive is high in peel strength and long in adhesion time.

Description

technical field [0001] The application relates to the field of building materials, more specifically, it relates to a self-adhesive waterproof coiled material supporting adhesive for low-temperature environment construction. Background technique [0002] With the country's increasingly stringent carbon emission management, traditional styrene-butadiene rubber waterproof membranes are gradually replaced by self-adhesive waterproof membranes. Self-adhesive waterproofing membrane can be used for cold construction, and its advantages in construction and environmental protection are self-evident. [0003] Self-adhesive waterproof membrane has good low-temperature flexibility, adhesive performance and self-healing property, but it still has the following defects in actual use: [0004] 1. The "Technical Specifications for Waterproofing of Underground Engineering" stipulates that the construction temperature of self-adhesive waterproof membranes is above 5°C, and the "Technical Sp...
