Problems solved by technology

[0003] At present, the waterproof membranes used in ports and wharfs in the prior art are continuously optimized in terms of waterproof performance. Due to the geographical location of ports and wharfs, strong winds and waves and ultra-high tides often occur, and the requirements for the wear resistance and compressive performance of the membranes are Higher, at present, the usual technical means to improve the wear resistance of PVC waterproof membrane is to add wear-resistant inorganic materials, but wear-resistant inorganic materials (fillers) will affect the compressive properties, tensile properties and flexibility of waterproof membranes etc., will directly reduce the overall performance of the waterproof membrane, reduce the service life, increase the replacement frequency, and increase the cost. This defect limits the application field and development of the product to a certain extent.

Abstract

The invention provides a super-weather-resistant composite waterproof roll. The super-weather-resistant composite waterproof roll is prepared from diisodecyl phthalate, epoxypropane glyceryl polyether, a tackifier, castor oil alkyd resin and zinc stearate. A preparation method disclosed by the invention comprises the following steps: carrying out plastifying at a temperature of 78 DEG C for 10 minat first, then performing mixing at a temperature of 85 DEG C for 30 min, and then carrying out cooling to 65 DEG C at a speed of 2 DEG C / min. According to the waterproof roll in the invention, lithium-based bentonite is used as an inorganic wear-resistant material, and then a certain amount of aluminate is added to improve the compatibility among components; and with the preparation method, obtained pellets are smooth, low in roughness coefficient, small in fluid resistance and high in uniformity, and the super-weather-resistant composite waterproof roll with integrated wear resistance, compression resistance, tensile properties and flexibility is obtained.

Description

technical field [0001] The invention belongs to the technical field of waterproof coiled materials, and relates to a super-weather-resistant composite waterproof coiled material, in particular to a super-weather-resistant composite waterproof coiled material and a preparation method thereof. Background technique [0002] The full name of polyvinyl chloride is Polyvinylchlorid, referred to as PVC, and the product name is referred to as "chlorine plastic". The main component is polyvinyl chloride, non-toxic and odorless, and the density is 1.40g / cm 3 , which is polymerized from vinyl chloride monomer, is one of the commonly used thermoplastics. These thermoplastic polymers are processed into useful products by extrusion, injection molding, compression molding and other thermoforming methods. The products are bright in color and durable. It has excellent acid resistance, alkali resistance and corrosion resistance; PVC waterproof membrane is especially suitable for ports and wha...
