摘要:
The present invention relates to a sheet of covering material, in particular a roof covering material, the use of said sheet as covering material, in particular for roofs, a building structure comprising a substrate, in particular a roof, covered with said sheet and a method for manufacturing said sheet.
摘要:
A polymer pre-laid waterproof rolling material, which comprises a polymer base material layer, a pressure-sensitive adhesive layer on the polymer base material layer, and a sand anti-sticking layer on the pressure-sensitive adhesive layer; wherein the pressure-sensitive adhesive layer includes: 25-35 parts by mass of a styrene-isoprene-styrene block copolymer; 32-38 parts by mass of a C5 petroleum resin; 5-12 parts by mass of a 145 pentaerythritol modified rosin resin; 25-32 parts by mass of a naphthenic oil; 0.3 parts by mass of an antioxidant; and 0.5 parts by mass of a UV light stabilizer; the C5 petroleum resin has a softening point of 95-105°C and a color number of less than 4; the naphthenic oil has a kinematic viscosity of 9-11 mm 2 at 100°C and a density of 0.8950 g/cm 3 -0.9100 g/cm 3 at 20°C. The pressure-sensitive adhesive layer has a stronger bonding with the sand of the sand anti-sticking layer and further has improved bonding to concrete applied on the sand anti-sticking layer.
摘要:
A membrane roofing system that includes a waterproof layer that protects an insulation layer and a granule coupled to the waterproof layer. The granule has a 65% or greater reflectivity that reduces transmission of ultraviolet light to the waterproof layer. The granule is coated in a fluorinated acrylic copolymer that resists adsorption and absorption of asphaltic chemicals by the granule from the waterproof layer.
摘要:
A device for heating and connecting sheets (11, 12, 111, 121) of bituminous or synthetic membranes (100), comprising at least one sheet (11, 12, 111, 121) of a bituminous or synthetic membrane (100) which is applied to at least one base layer (141), said membrane (100) being formed with a single compound or having at least one bottom layer including a compound or a bituminous mixture and at least one upper layer including a polymeric material and an electrically conductive material, which is heated; in particular, a body (13, 23) having a mainly longitudinal (A) development and placed on a first edge (11a, 21a) of a first sheet (11, 21, 111, 121) of the membrane (100) in order to connect said first edge to a second edge (12a, 22a) of a second sheet (12, 22, 111, 121) of the membrane (100) is provided with an upper face (13a, 23a).
摘要:
A low radiant energy absorbing roofing product having a near-infrared (near-IR) reflective polymer in a substrate layer and a near-IR transmissive polymer in a second layer. The substrate layer is near-IR reflective to minimize radiant energy absorption, even while the second layer is provided with a dark color. Pigments are contained within the co-extruded polymers to provide a durable finished product.
