Abstract
The invention discloses a self-adhesion silica gel powder-modified asphalt waterproof coiled material which is of a three-layer composite structure and is characterized in that a middle layer is polyester tire cloth and silica gel powder-modified asphalt layers filled with silica gel powder and thickening agents are arranged on the upper and lower surfaces. The invention provides a formula and a process for preparing the self-adhesion silica gel powder-modified asphalt waterproof coiled material. The self-adhesion silica gel powder-modified asphalt is prepared by mixing asphalt, the thickening agents, silica gel powder modifying agents and the like. After the coiled material is modified by the silica gel powder, the coiled material is free of bubbles and slip when being heated for 2 hours at the temperature of 120 DEG C, has low-temperature flexibility of -40 DEG C and does not have cracks, so that the application range of the self-adhesion silica gel powder-modified asphalt waterproof coiled material is expanded.
Description
1, technical field
The present invention relates to construction engineering waterproof material, be applicable to waterproof between roof waterproof, underground waterproof, tunnel water proofing, railway waterproof, the bath of lavatory, kitchen, refer more particularly to a kind of self-adhesion silica-gel powder modifying asphalt prescription and technology.
2, background technology:
1) appearance of self-adhesion silica-gel powder modified asphalt waterproof coiled material, solved the abominable shortcoming of construction environment, the silastomer goods that to lose have namely improved coiled material greatly in processing activated adding waterproof roll performance also turns waste into wealth, and becomes widely used waterproof material.
2) learn with exploitation after deliberation, adopt various polymer modified asphalts can improve the use properties of pitch base material greatly.Silica-gel powder is for the general polymer modifying asphalt, and the high temperature anti-current is dropped down, low temperature cracking resistance ability can improve greatly, and ageing-resistant and weathering resistance strengthens and the adhesive capacity of base material also increases.
3, summary of the invention:
1) the purpose of this invention is to provide a kind of silica-gel powder modifying asphalt adhesive waterproof coil, performance surpasses national standard, and self-adhesion silica-gel powder modified asphalt waterproof coiled material energy-conservation, that environmental field is interior.
2) the invention provides a kind of self-adhesion silica-gel powder modified asphalt waterproof coiled material, be three-layer composite structure, its middle layer is polyester blank cloth, and the upper and lower surface of polyester blank cloth is and adds silica-gel powder modifying asphalt self-adhesive layer.
3) tackifier are selected from machine oil, petroleum resin, liquid coumarone.
4) the invention provides the production method of described self-adhesion silica-gel powder modified asphalt waterproof coiled material.Batching and processing step are as follows:
A, batching: amount is than being that 90 pitches 100, silica-gel powder 10-20, tackifier 10-20 the present invention are owing to having adopted silica-gel powder to make the performance of waterproof roll substantially exceed national standard, this kind coiled material is after the silica-gel powder modification, 120 ℃ of high temperature, heating 2h does not have bubble, fricton-tight, low-temperature tenderness-40 ℃, therefore flawless has enlarged the range of application of self-adhesion modified asphalt waterproof coiled material.
B, at temperature 120-180 ℃, with pitch, silica-gel powder properties-correcting agent, tackifier, add mixing equipment, obtain self-adhesion silica-gel powder modifying asphalt, pass through forming technology of coiled material then, with in the middle of polyester blank is arranged in, the self-adhesion silica-gel powder modifying asphalt that makes evenly is coated in the upper and lower surface of polyester blank cloth, again through cooling, meter length, side cut, rolling, packing.
C, used pitch are that 90#, properties-correcting agent are that silica-gel powder, tackifier are petroleum resin and liquid coumarone.
5) bright spot of the present invention:
The appearance of a, self-adhesion silica-gel powder modified asphalt waterproof coiled material, the silastomer goods that will lose have namely improved coiled material greatly in processing activated adding waterproof roll performance also turns waste into wealth, and becomes widely used waterproof material.
B, learn with exploitation after deliberation, adopt various polymer modified asphalts can improve the use properties of pitch base material greatly.Silica-gel powder is for the general polymer modifying asphalt, and the high temperature anti-current is dropped down, low temperature cracking resistance ability can improve greatly, and ageing-resistant and weathering resistance strengthens and the adhesive capacity of base material also increases.
