Problems solved by technology

[0002] In the process of roof repair or roof waterproofing, the waterproof membrane is usually pasted directly on the roof. It is not only convenient to paste, but also can effectively achieve waterproof performance. PVC material is used because of its high chemical stability, light weight and good waterproof performance. It is mainly used in the preparation of waterproof membranes, but the anti-aging performance of PVC materials is poor, which affects the performance of PVC materials. Therefore, anti-aging effects can be achieved by adding anti-aging agents to the materials, but because the waterproof membranes laid on the roof are often exposed to sunlight The existing anti-aging agents cannot meet the anti-aging requirements, and although the PVC waterproof membrane has a certain thermal insulation performance, its thermal insulation performance is low

Embodiment 1

[0022] The specific preparation process of the antioxidant is as follows: ① Weigh 15g of mercaptosuccinic acid and add it to 300mL of ether and stir to dissolve it, then add 26.2g of thionyl chloride to it, raise the temperature to 70-80°C and stir for 5-6h, then depressurize Distill to obtain mercaptosuccinyl chloride; ②Add 9.4g phenol and 150mL ethanol to the reaction vessel at the same time, then add 0.94g potassium carbonate to it, stir and mix for 3-5min, then add 11.5g mercaptosuccinyl chloride to it, stir and react at room temperature for 8 -10h, then the obtained product was evaporated to remove the solvent therein to obtain a powder product, the powder was added to water and stirred for 2-3min, then filtered and dried to obtain product A; ③ 10g of obtained product A and 200mL nitrobenzene were simultaneously Put it into the reaction vessel, add 4.5g aluminum chloride and 2.1g titanium tetrachloride to the reaction vessel at the same time, raise the temperature to 165°C...

Embodiment 2

[0024]The specific preparation process of the polyvinyl chloride waterproof layer is as follows: 800g of polyvinyl chloride and 10g of the antioxidant prepared in Example 1 were simultaneously added to the internal mixer for 60-70min mastication, and the obtained material was mixed with 20g of quartz powder, 10g of hard Fatty acid, 70g of polydimethylsiloxane, 30g of carbon black and 20g of plasticizer were extruded into a screw extruder to obtain a polyvinyl chloride waterproof layer with a thickness of 0.9mm.

Embodiment 3

[0026] The specific preparation process of the polyvinyl chloride waterproof layer is the same as in Example 2, and the antioxidant prepared in Example 1 used in Example 2 is replaced by the anti-aging agent IPPSI.

Abstract

The invention discloses a multi-layer building roof heat-preservation waterproof coiled material which comprises a fiber heat-insulation layer; the upper surface and the lower surface of the fiber heat-insulation layer are respectively compounded with a polyvinyl chloride waterproof layer through a pressure-sensitive adhesive, and then the bottom surface of the polyvinyl chloride waterproof layerat the bottom is compounded with a layer of release paper through the pressure-sensitive adhesive. The two polyvinyl chloride waterproof layers are arranged, the fiber heat insulation layer is arranged between the two polyvinyl chloride waterproof layers, and the heat insulation performance of the waterproof coiled material can be improved through the heat insulation effect of the fiber heat insulation layer, so that the prepared waterproof coiled material not only has high waterproof performance, but also can achieve the heat preservation capacity.
