Waterproof flame-retarding composite coiled material and preparation method thereof

Abstract

The invention discloses a waterproof flame-retarding composite coiled material and a preparation method thereof. According to the invention, recycled waste materials are mainly used as a raw material; solid-state epoxy resin is added to the waste materials, such that the strength and corrosion resistance are improved, and physical and chemical cross-linking effects among the materials can be provided; other components such as a fire retardant, a waterproof agent, a curing agent and a vulcanizing agent are added to the materials; the materials are mixed, and the mixture is subject to a calendering technology, such that the coiled material is prepared. During the process, no adhesive is used, and no harmful substance is generated. The prepared coiled material is advantaged in high strength, good stability, good deformation resistance, high flatness, excellent moisture resistance, good nail-holding power, good flame retardance, good water resistance, and good corrosion resistance.

Description

technical field [0001] The invention relates to a waterproof material and a preparation method thereof, more specifically, to a waterproof and flame-retardant composite coil prepared from waste raw materials and a preparation method thereof. Background technique [0002] With the development of my country's economic construction, there is an urgent need for an advanced waterproof material in the difficult waterproofing of large-scale infrastructure construction such as high-speed railways, subways, tunnels, and water conservancy projects. This kind of waterproof coating should overcome the shortcomings of traditional waterproof materials such as aging resistance, no exposure, low strength, no puncture resistance, high requirements on the construction environment, slow curing, and low work efficiency. The polyurea waterproof material in the prior art is a material with a 100% solid content, which utilizes the -NCO of the A component and the -NH of the B component 2 It is sol...

Problems solved by technology

At present, the recycling and reuse of waste plastics in my country is not ideal. Most of them are simply used, with low technical level and lack of market competitiveness. Most of the waste plastics are used to make composite materials such as plastic wood and thermal cracking to produce lubricants, Gasoline, diesel, heat-shrinkable materials, etc., the preparation method is complicated, the technical level is low, the energy consumption is large, and it is easy to cause secondary pollution

At present, the recycling status of thermosetting foam plastic waste in my country is not ideal. Most of them only develop and utilize thermoplastic foam plastics that are easy to regenerate, and there is a lack of recycling methods for thermosetting foam plastics that are difficult to regenerate.
