Embodiment 1

[0022] A kind of manufacturing method of waterproof coiled material adopts such as Figure 1~2 The equipment shown is manufactured. First, 15% calcium carbonate, 1% plastic defoamer, and the remaining amount of polyethylene are stirred and mixed for 4 minutes through the raw material compounding device 1; then the mixed polyethylene mixture is extruded The outlet device 2 is melted and plasticized, and the plasticizing temperature is 220°C. After melting and plasticizing, a film with a thickness of 1.0mm is extruded from the die head 21 of the extrusion device 2 and is in a molten state; then the above-mentioned film and the two-layer non-woven fabric The substrates are laminated, pressed and bonded and cooled by the metal cooling roller of the compound device 4 to form a composite material; finally, the above composite material is pulled by the guide roller 6 and the traction device 7, and then transported to the double-station center coil Take machine 8 and wind up into coil...

Abstract

The invention relates to a production method of a waterproof rolled material for construction engineering and a device for producing the material. The production method comprises the following steps: mixing polyethylene with calcium carbonate and plastic antifoaming agent, extruding a film through plasticizing and fusion, then laminating the film with two layers of non-woven fabrics, compacting and bonding by a laminating device and cooling to obtain a composite material, drawing the composite material through a guide roller and a draw gear, conveying the drawn composite material to a double station center reeling machine for reeling to obtain the rolled material. The produced waterproof rolled material has the advantages of good structural behavior, and excellent peel strength, tensile strength, fracture resistance, percentage elongation, aging resistance and other comprehensive properties. The device for producing the material comprises a raw material proportioning and blending unit, a first unreeling unit, the laminating device, the draw gear and the double station center reeling machine, and also comprises an extrusion unit arranged at one side of the laminating device and a second unreeling unit for sending the rolled material to the laminating device, and a printing device and a clipping device which are successively arranged at the back of the laminating device and at the front of the draw gear. The device has the advantages of simple structure and convenient operation.

Description

technical field [0001] The invention relates to a method for manufacturing waterproof coiled material for construction engineering and equipment for manufacturing the waterproof coiled material. Background technique [0002] The traditional asphalt felt waterproof material can no longer adapt to the requirements of the new situation. Some developed countries in foreign countries have widely used polymer waterproof membranes and advanced equipment. In order to meet the needs of the domestic construction industry, a polymer composite waterproof membrane with good structural performance has been developed. Due to the high price of imported equipment, it is urgent to provide the production process and production equipment for the waterproof membrane in combination with my country's national conditions. Contents of the invention [0003] The technical problem to be solved by the present invention is: based on the above problems, the present invention provides a method for manuf...
