Problems solved by technology

[0003] The existing non-bitumen-based polymer self-adhesive waterproofing membrane is made of LDPE, HDPE, POE, EVA and other resin base materials, filled with various powder fillers in a certain proportion, and melted and extruded by roll forming. It is made of LDPE, HDPE , TPO, POE, EVA, etc. are non-polar resins or resins are extremely low, the surface tension of the polymer sheet is very small, the wettability is poor, and the coating of the self-adhesive layer binder on it is poor, so As a result, the peel strength between the self-adhesive layer and the polymer sheet layer is low, and a high-performance self-adhesive waterproof membrane cannot be obtained.

Embodiment 1

[0021] A preparation of high peel strength non-bitumen-based self-adhesive membrane polymer sheet: calculated in parts by weight, including: 70 parts of low-density polyethylene (LDPE), 5 parts of maleic anhydride graft modified polyethylene (MAH -g-PE), 25 parts of light calcium carbonate, 0.2 part of UV-9 ultraviolet absorber, 0.1 part of 1010 primary antioxidant, 0.2 part of 168 auxiliary antioxidant, 0.3 parts of stearic acid and 3 parts of iron dioxide.

[0022] The steps of a production process of a TPO waterproof coiled material are as follows:

[0023] a. Mixing: Mix the measured raw materials (mixing conditions) evenly:

[0024] b. Extrusion and calendering: the mixed raw materials are plasticized and extruded through a twin-screw extruder. At 220±10°C, the extruded sheet is calendered by a three-roller calender;

[0025] c. Glue coating: The calendered polymer sheet is glued on the glue coating machine, using SIS pressure-sensitive hot melt adhesive, the melting t...

Embodiment 2

Abstract

The invention discloses a non-asphalt-based high polymer self-adhered waterproof membrane with high peel strength and relates to the field of waterproofing of buildings. The production raw materials comprise LDPE (low density polyethylene), maleic anhydride graft modified polyethylene, light calcium carbonate with surface treated with a silane coupling agent, an ultraviolet light absorber, a main antioxidant, an auxiliary antioxidant, stearic acid and titanium dioxide. The non-asphalt-based high polymer self-adhered waterproof membrane has the advantages of high peel strength, high tensile strength, high elongation, good low-temperature bending performance, good corrosion resistance, firm fixation and good waterproof effect, besides, the product is moderate in softness, high in weldability and high in welding strength and facilitates construction.

Description

technical field [0001] The invention relates to a non-asphalt-based macromolecule self-adhesive waterproof coiled material with high peeling strength and a preparation method thereof, belonging to the field of building waterproofing. Background technique [0002] Non-bitumen-based polymer self-adhesive waterproofing membrane is a new environmentally friendly polymer waterproofing material, which has been widely recognized due to its excellent physical and mechanical properties, reliable installation and excellent performance confirmed by long-term use. In the process of pre-paved waterproofing construction, the non-asphalt-based polymer self-adhesive waterproofing membrane has a self-healing function. After reacting with liquid concrete slurry and consolidating, it forms a gap-free combination of the waterproofing layer and the concrete structure, preventing water leakage between the waterproofing layers. Hidden dangers can effectively improve the effectiveness of the waterp...
