Method for manufacturing anti-flaming waterproof ventilated cushion

Abstract

The invention provides a method for manufacturing an anti-flaming waterproof ventilated cushion, and relates to the technical field of manufacturing a composite material with functions of flame retardance, water prevention and ventilation. The method comprises the following steps of: firstly, carrying out mixing granulation on polypropylene H2800, metallocene polyethylene, Exxon Mobil elastomer PP6002, nano calcium carbonate, a coupling agent, a dispersing agent, a lubricating agent and chlorinated paraffin, so as to form a sheet material; secondly, heating and stretching the sheet material to manufacture a copolymerization microporous membrane; thirdly, thermally pressing polypropylene non-woven fabrics on the two surfaces of the copolymerization microporous membrane through a hot roll, so as to form a three-in-one semi-finished product; and finally, soaking the three-in-one semi-finished product in mixed impregnation liquid containing a fire retardant, a hydrophilic agent, and a silane coupling agent JS-D758, and drying through using a drying cylinder, so as to form the anti-flaming waterproof ventilated cushion. The anti-flaming waterproof ventilated cushion manufactured by using the method by the invention is applicable to a metal roof, a pitched roof, and one layer of protection film outside thermal-insulating cotton and rock wool. Due to the specific ventilation property of the anti-flaming waterproof ventilated cushion manufactured by using the method provided by the invention, water inside a building structure is rapidly discharged, so that the flame retardance can be shown in the case of fire, and the loss can be reduced.

Description

technical field [0001] The invention relates to the technical field of making composite materials with flame-retardant, waterproof and air-permeable functions. Background technique [0002] At present, thermal insulation cotton and rock wool outer protective film on the market have poor thermal insulation performance. In addition, they are prone to spread when exposed to fire, and their fire safety performance is poor, which cannot meet the needs of modern industries or buildings. Contents of the invention [0003] The object of the present invention is to propose a method for making a flame-retardant waterproof air-permeable cushion with flame-retardant, waterproof, and breathable functions. [0004] The present invention comprises the following steps: [0005] 1) After mixing polypropylene H2800, metallocene polyethylene, ExxonMobil elastomer PP6002, nano-calcium carbonate, coupling agent, dispersant, lubricant and chlorinated paraffin, extrude through twin-screw to gra...
