Problems solved by technology

At present, domestically produced EPDM waterproof membranes, polyethylene polypropylene fiber composite waterproof membranes, PVC waterproof membranes, ternary butyl rubber membranes, polyurethane waterproof membranes, etc. only consider the waterproof performance of the membranes. , ignoring the flame retardant performance, so there are widespread fire safety hazards
Polyurethane flame-retardant and waterproof membranes are widely used in thermal insulation structures of equipment and pipelines in petroleum, chemical, electric power, construction, etc. Although they have good waterproof and flame-retardant properties, the cost of use is quite high, and it is difficult to promote and popularize.

Embodiment 1

[0015] a. Ingredients mixing: put 62.5% linear low density polyethylene resin, 1.5% light shielding agent, 1.5% antioxidant, 1.0% adhesion promoter, 33% flame retardant masterbatch, 0.5% dispersant Stir evenly in the container, the unit is percentage by weight; b, one-time hot-melt direct pressure: put the stirred material into the screw extruder, and melt and extrude it into a resin film through the screw extruder at a temperature of 155°C; c, two Secondary hot-melt direct pressure: While extruding the resin film, introduce the non-woven fabric into a pair of drafting rollers from both sides at the same time, and through the extrusion of the rollers, the non-woven fabric and the resin film are hot-pressed and combined into one, the temperature is 165 ℃ to form a waterproof membrane. The flame retardant masterbatch is mainly composed of 81.1% polyolefin resin, 2.5% polyethylene wax, 14% coupling agent, 1.2% white oil and 1.2% zinc stearate. Due to the relatively high content ...

Embodiment 2

[0017] a. Ingredients mixing: put 70.4% linear low density polyethylene resin, 0.5% light shielding agent, 0.5% antioxidant, 0.5% adhesion promoter, 28% flame retardant masterbatch, 0.1% dispersant Stir evenly in the container, the unit is percentage by weight; b, one-time hot-melt direct pressure: put the stirred material into the screw extruder, and melt and extrude it into a resin film through the screw extruder at a temperature of 165°C; c, two Secondary hot-melt direct pressure: While extruding the resin film, introduce the non-woven fabric into a pair of drafting rollers from both sides at the same time, and through the extrusion of the rollers, the non-woven fabric and the resin film are hot-compressed into one body, and the temperature is 155 ℃ to form a waterproof membrane. The flame retardant masterbatch is mainly composed of 80% polyolefin resin, 2.5% polyethylene wax, 15.1% coupling agent, 1.2% white oil and 1.2% zinc stearate. The flame retardant masterbatch used...

Embodiment 3

[0019] a. Ingredients mixing: put 66.5% linear low density polyethylene resin, 0.7% light shielding agent, 0.9% antioxidant, 0.6 adhesion promoter, 31.0% flame retardant masterbatch, 0.3% dispersant Stir evenly in the container, the unit is percentage by weight; b, one-time hot-melt direct pressure: put the stirred material into the screw extruder, and melt and extrude it into a resin film through the screw extruder at a temperature of 160°C; c, two Secondary hot-melt direct pressure: While extruding the resin film, introduce the non-woven fabric into a pair of drafting rollers from both sides at the same time, and through the extrusion of the rollers, the non-woven fabric and the resin film are hot-compressed into one body, the temperature is 160 ℃ to form a waterproof membrane. The composition of the flame retardant masterbatch is mainly composed of 80.9% of polyolefin resin, 1.5% of polyethylene wax, 16% of coupling agent, 0.8% of white oil, and 0.8% of zinc stearate. Acco...

Abstract

The chemical composition of waterproof coiled material is composed of linear low density polyvinyl resin, light shielding agent, antioxygen, dispersing agent, stick-supporting agent and fire resisting masterbatch. The present invention can raise fire fighting safety of the waterproof coiled material.

Description

technical field [0001] The invention relates to building materials and petrochemical industries, in particular to a polyethylene polypropylene polymer composite flame-retardant and waterproof material. Background technique [0002] With the continuous development of the petrochemical industry in the construction industry and the continuous improvement of the country's fire protection requirements for various industries, higher requirements are also put forward for waterproof materials. At present, the domestic production of EPDM waterproof membranes, polyethylene polypropylene fiber composite waterproof membranes, PVC waterproof membranes, ternary butyl rubber membranes, polyurethane waterproof membranes, etc. only consider the waterproof performance of the membranes. , ignoring the flame retardant performance, so there are widespread fire safety hazards. Polyurethane flame-retardant and waterproof membranes, which are widely used in thermal insulation structures of equipme...
