Non asphalt based self-adhesive film

Product Introduction

Non asphalt based polymer self-adhesive waterproofing membrane is a new type of waterproofing material widely used in waterproofing engineering design; The roll material is made of polymer material as the substrate and coated with a non asphalt based * * * polymer self-adhesive adhesive layer composite*** The aging resistance of the polymer self-adhesive layer is greatly improved, which is superior to the aging performance of general polymer coil layers.

2 Product Features

1. Non asphalt based polymer self-adhesive waterproofing membrane combines the advantages of polymer waterproofing membrane and self-adhesive membrane, greatly improving its puncture resistance, self-healing, high and low temperature resistance, and more stable chemical properties;

2. Yinhai non asphalt based polymer self-adhesive waterproofing membrane adopts self-adhesive construction technology, which is more convenient for construction;

3. The self-adhesive layer adopts the * * * polymer self-adhesive developed by our company, which greatly improves the aging resistance and ensures the permanent self-adhesive effect;

4. Yinhai non asphalt based polymer self-adhesive waterproofing membrane has achieved the possibility of preventing water leakage in polymer membranes;

5. Security * * *; The polymer substrate and self-adhesive material both use the * * * formula of --.

Construction method

According to different requirements such as engineering structure, engineering category, engineering design, and usage standards, wet laying or pre laying (tunnel hanging laying) construction methods can be selected.

Grassroots treatment: Clean the surface of the base layer. The base layer can be damp, but there should be no visible water. If the base layer is dry, it needs to be moistened with water. Preparation of cement slurry: Directly add water to cement (not less than 32.5R grade ordinary silicate cement), cement: water=1:0.3~0.4 (weight ratio, reasonable investigation according to actual situation), stir with an electric mixer for 1-2 minutes, mix well and let it stand for 5-8 minutes.

Roll pasting: Use a trowel or scraper to evenly apply the mixed cement slurry on the base layer, and lay the polymer self-adhesive waterproof roll on top while scraping, and then exhaust and compact it.

Joint pasting: The joint of the roll material adopts cold self-adhesive method. The adjacent short edge joints should be staggered by more than 1m; When constructing the long edge joint, remove the reserved isolation tape on the self-adhesive edge of the joint, align it with the adhesive marking line, and directly paste it; Then use specialized sealing paste to strengthen the sealing and finishing treatment (hot air welding can be used for overlapping parts).

Scope of application
