Abstract
The utility model relates to the field of waterproof engineering of roofs, in particular to a hot-melting calendaring composite polyvinyl chloride waterproof roll. Polyester fabrics serve as a framework layer, a pasty polyvinyl chloride (PVC) adhesion layer is coated at the back side with 30 to 40 kilograms in every square meters, a pasty PVC adhesion layer is coated on the front side with 40 to 60 kilograms in every square meters, a PVC film is coated at the back side with 500 to 550 kilograms in every square meters, a PVC film layer (1) is coated at the front side with 500 to 550 kilograms in every square meters, and a PVC film layer (2) is coated on the front side with 200 to 250 kilograms in every square meters. The hot-melting calendaring composite polyvinyl chloride waterproof roll resolves the problem that an existing PVC waterproof roll is easy to accumulate dust due to the concave-convex surface.
Description
Technical field
The utility model relates to the roof waterproof engineering field, particularly hot melt calendering Polyvinyl chloride plastic sheets for waterproofing.
Background technology
Roof waterproof engineering is an important engineering of building construction, and life-span, resident family that the workmanship quality directly influences building produce and life.Roof leakage is a modal common fault in the construction work, guarantee the quality of waterproofing, and design is a prerequisite, and construction is crucial, also will select suitable waterproofing materials.Particularly in the South China, temperature is high, solar radiation is strong, rainwater is many, and the selection of waterproofing materials seems more important.At present, most polyvinyl chloride (be called for short PVC) waterproof roll be with polyester tricot as casing play, surperficial applying PVC film is as waterproofing course.PVC film and polyester textile caking property extreme difference in the process of construction, are easy to generate two-layer PVC waterproofing course and come off, and cause the phenomenon of roof leakage to take place.And polyester tricot is a net structure, and the compound back of direct and PVC film is prone to produce concave-convex sense, and the surface is accumulated dust easily, and self-cleaning is poor, influences the reflecting effect of PVC waterproof roll.
Summary of the invention
The utility model is the problem to the existing technical existence of Polyvinyl chloride plastic sheets for waterproofing; A kind of hot melt calendering composite polrvinyl chloride waterproof roll that solves polychloroethylene film and polyester textile bad adhesion that proposes; And can make the Polyvinyl chloride plastic sheets for waterproofing surfacing, dust stratification dirt and reach high reflective effect not.
The technical scheme that the utility model adopts: a kind of hot melt calendering composite polrvinyl chloride waterproof roll, with polyester tricot as casing play 1; Reverse side is coated with paste polyvinyl chloride tack coat 3,30-40g/m
2Front surface coated has paste polyvinyl chloride tack coat 2,40-60g/m
2Reverse side is coated with layers of polyvinyl chloride films 5,500-550g/m
2Front surface coated has layers of polyvinyl chloride films 1,500-550g/m
2Front surface coated has layers of polyvinyl chloride films 26,200-250g/m
2
Above-mentioned casing play 1 is that the woven density of 1000D-1500D broadwise 1000D-1500D is that warp-wise 9-12 root/inch broadwise is 9-12 root/inch polyester tricot for the thickness of yarn warp-wise;
Above-mentioned positive and negative coating paste polyvinyl chloride tack coat 2, tack coat 3 adopt mode, warm-up mill and the infrared rays Gel Treatment of roller coat.
Add the tackifier that contain isocyanates in above-mentioned positive and negative tack coat 2, the tack coat 3; Isocyanates can effectively combine with polyester tricot; It makes an addition in the paste polyvinyl chloride; Can well combine with the polyvinyl chloride calendered film again, strengthen the peel strength between the hot melt calendering Polyvinyl chloride plastic sheets for waterproofing level greatly, be prone in using process, can significantly reduce surface decortication phenomenon.
Above-mentioned front surface coated paste polyvinyl chloride tack coat 2 can effectively be filled and led up the jog of polyester tricot.
Above-mentioned positive and negative coating layers of polyvinyl chloride films 1, layers of polyvinyl chloride films 5, layers of polyvinyl chloride films 26 adopt hot melt calendering coating method, and directly cooling and shaping is handled.
Above-mentioned front surface coated layers of polyvinyl chloride films 26 is for having the white or the milky polychloroethylene film of uvioresistant, reflection function.
The effect of the utility model:
1. pass through in this product structure, to increase tack coat 2, tack coat 3, layers of polyvinyl chloride films 26 has strengthened casing play and layers of polyvinyl chloride films 1, the adhesive property of layers of polyvinyl chloride films 5.
2. tack coat 2 has been filled and led up the recessed position of casing play, makes product surface smooth, has reduced existing Polyvinyl chloride plastic sheets for waterproofing surface irregularity and the phenomenon that accumulates dust.
Description of drawings
Fig. 1 is the structural representation of the utility model hot melt calendering composite polrvinyl chloride waterproof roll.
Among the figure: 1---casing play; 2---tack coat; 3---tack coat; 4---layers of polyvinyl chloride films one; 5---layers of polyvinyl chloride films; 6---layers of polyvinyl chloride films two.
Below in conjunction with accompanying drawing the utility model is specifically described:
As shown in Figure 1, casing play 1 is 1300D for the thickness of yarn warp-wise, and broadwise is 1300D; Woven density is that 12/inch of warp-wise broadwise is 12/inch;
The utility model hot melt calendering composite PVC waterproof roll performance indications
