Problems solved by technology

[0006] Both the main waterproof layer and the self-adhesive layer of the waterproof membrane are made of butyl rubber, which can effectively solve the problems of poor bonding compatibility and poor weather resistance of non-body materials in the prior art
However, the main waterproof layer and the self-adhesive layer are made of butyl rubber as the main raw material, and there will be problems of complicated production process and high production cost.

Embodiment 1

[0051] 1. Preparation of butyl rubber coarse compound

[0052] Waste butyl rubber to remove impurities, cut into small pieces, and set aside.

[0053] Add 50kg of waste butyl rubber cut into small pieces into a 55-liter pressurized kneader, control the temperature at about 90°C, and carry out rough mixing for about 6 minutes; then add 10kg of carbon black within 8 minutes and continue mixing refining, to obtain butyl rubber rough mix.

[0054] 2. Prepare the base layer of butyl rubber waterproof membrane

[0055] Add 15kg of butyl rubber rough mix, 12kg of 325 mesh light calcium carbonate, 0.045kg of paraffin, and 0.045kg of stearic acid into a high-speed mill with an automatic feeding device. The speed ratio of the high-speed mill is 1 : more than 1.575, the temperature is blended into a butyl rubber sheet I with a thickness of about 0.5mm at about 70°C.

[0056] Use a three-roller calender to make butyl rubber sheets I into butyl rubber waterproof membrane bases of differ...

Embodiment 2

[0063] 1. Preparation of butyl rubber coarse compound

[0064] Waste butyl rubber to remove impurities, cut into small pieces, and set aside.

[0065] Add 45kg of waste butyl rubber cut into small pieces into a 55-liter pressurized kneader, control the temperature at about 90°C, and carry out rough mixing for about 6 minutes; then add 8kg of carbon black within 8 minutes and continue mixing refining, to obtain butyl rubber rough mix.

[0066] 2. Prepare the base layer of butyl rubber waterproof membrane

[0067] Add 19kg of butyl rubber rough mix, 17kg of 325 mesh light calcium carbonate, 0.04kg of paraffin, and 0.06kg of stearic acid into a high-speed mill with an automatic feeding device. The speed ratio of the high-speed mill is 1 : Above 1.575, the temperature is blended into butyl rubber sheet I at about 75°C.

[0068] Use a three-roller calender to make butyl rubber sheets I into butyl rubber waterproof membrane bases of different thicknesses, with a line speed of 17-...

Abstract

The invention provides a method for manufacturing self-adhesive butyl rubber waterproof membrane, which uses solid waste butyl rubber, does not require high-temperature desulfurization, uses high shear force, controls the operating temperature below 100°C, and directly produces butyl The base layer of base rubber waterproof membrane is used as the main waterproof layer; the middle butyl rubber self-adhesive layer is also a paste self-adhesive made of waste butyl rubber, which is used as an auxiliary waterproof layer; the lower surface is made of removable anti-adhesive paper isolated. The waterproof coiled material of the invention has excellent water resistance and outstanding aging resistance, and is energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to a method for manufacturing self-adhesive butyl rubber waterproof coiled material. Background technique [0002] Waterproof membrane is a commonly used material in building construction. It is mainly used for waterproof construction of building roofs and underground works, and plays a vital role in resisting the leakage of rainwater and groundwater. Today, due to the pollution of the atmosphere and underground, waterproofing membranes must not only have excellent weather resistance, but also have corrosion resistance and chemical stability. [0003] Self-adhesive butyl rubber waterproof membrane, including the main waterproof layer, butyl rubber self-adhesive layer and anti-adhesive film, wherein the main waterproof layer and butyl rubber self-adhesive layer are combined together, and the anti-adhesive film is set on the butyl rubber The lower surface of the self-adhesive layer. Most of the main waterproof layers of self-adhes...
