The invention relates to a wear-resistant anti-slip TPO waterproof coiled material and a preparation method thereof.
Background
With the rise of distributed photovoltaic construction, the service life of a roof is required to be higher and higher by an owner, the same service life of the roof and a distributed photovoltaic module needs to be met, and the service life of the roof reaches 25-30 years.
TPO waterproofing membrane's waterproof weatherability is fit for distributing type photovoltaic very much, and TPO waterproofing membrane uses widely in the waterproof separation engineering, has the weatherability, and high temperature resistant, low temperature resistance can all be fine, and the pliability is good, has better limited slip performance.
However, the distributed photovoltaic roof has the requirement of being frequently accessible to the roof and needs to be frequently maintained, so that the waterproof roll is required to have good surface wear resistance, good slip resistance and good weather resistance. Whereas existing TPO coils are not abrasion resistant. Aiming at the point, the invention provides a wear-resistant anti-slip TPO waterproof coiled material and a preparation method thereof.
Disclosure of Invention
The invention aims to provide a wear-resistant anti-slip TPO waterproof coiled material which comprises the following components in parts by mass:
preferably, the TPO elastomer has a density of less than 0.88g/cm 3 。
Preferably, the SEBS has a star-shaped structure.
Preferably, the elongation at break of the SEBS is not less than 400%.
Preferably, the mass ratio of the total amount of the TPO elastomer and the SEBS to the PP is 3:7 to 4:6.
Preferably, the light stabilizer is selected from one or more of hindered amine, o-hydroxybenzophenone and benzotriazole.
Preferably, the antioxidant is selected from one or more of 2,6-bis (1,1-dimethylethyl) -4-methylphenol, pentaerythrityl tetrakis [ beta- (3,5-di-tert-butyl-4-hydroxyphenyl) propionate ], pentaerythrityl tetrakis (3,5-di-tert-butyl-4-hydroxy) phenylpropionate, and tris (2,4-di-tert-butylphenyl) phosphite.
The invention also provides a preparation method of the wear-resistant anti-slip TPO waterproof coiled material, which comprises the following steps:
1) Adding PP, TPO elastomer and SEBS into a high-speed mixer, and uniformly mixing at normal temperature to obtain a first mixture; then adding the first mixture into a main feeding port of a double-screw extruder for blending granulation to obtain a granulation material;
2) Adding titanium dioxide, a light stabilizer and an antioxidant into a high-speed mixer, and uniformly mixing at normal temperature to obtain a second mixture;
3) Adding the granulated material obtained in the step 1) into a main feeding port of a double-screw extruder, adding the second mixture obtained in the step 2) into a side feeding port of the double-screw extruder, melting and extruding a sheet through the extruder, calendering by a three-roller system, cooling, forming and rolling to obtain the wear-resistant and anti-slip TPO waterproof coiled material.
Preferably, in the step 1), the processing temperature of the extruder is 170 to 200 ℃, the screw rotation speed is 80rpm, the drawing speed is 12m/min, and the particle size of the granulated material is controlled to about 6mm.
Preferably, in the step 3), the processing temperature of the extruder is 170-200 ℃, the screw rotation speed is 15rpm, the traction speed is 0.9m/min, and the tension is controlled to be 10N +/-5N.
The invention has the advantages and beneficial effects that: the TPO waterproof coiled material has the advantages of good static friction coefficient, good slip resistance, good wear resistance, good weldability, good low temperature resistance and high temperature resistance, and is very suitable for the photovoltaic roof of people.
SEBS (polypropylene ethylene) is a thermoplastic block copolymer, has good weather resistance and good elasticity due to hydrogenation, has higher Tg due to the addition of styrene, forms an interpenetrating network structure in the blending process with PP and TPO elastomers, strengthens the physical crosslinking performance, has higher wear resistance and better skid resistance compared with a linear structure due to the wear resistance of a star structure, is softer and has good flexibility, so that the TPO waterproof coiled material has better static friction coefficient and better skid resistance; and the low temperature resistance and the high temperature resistance are good.
However, SEBS is in an amorphous structure, has poor surface welding performance, and needs to be blended with TPO elastomer to obtain better welding performance, so that the content needs to be controlled, and the welding efficiency and the abrasion resistance need to be balanced. If too much SEBS is added, the mechanical properties (especially the elongation at break) of the TPO waterproof coiled material can be reduced rapidly and are lower than the standard of the TPO waterproof coiled material.
TPO elastomer's melting range is very wide, and the crystallinity is low, when improving waterproofing membrane pliability, can promote welding efficiency, simultaneously because the pliability is high, the coefficient of static friction is also high, has fine limited slip performance, can prevent that people's operation from slipping to tumble injury on the roofing. However, the TPO elastomer has the defects of no abrasion resistance, serious mass abrasion and hidden danger of leakage when a roof is stepped by a person for a long time. The adopted star SEBS is soft and has good blending dispersibility with TPO material, so the material still has slip resistance and good wear resistance; is very suitable for the photovoltaic roof of people.
The traditional method adopts wear-resistant auxiliary agents (such as silicone materials) and achieves the purpose of wear resistance by improving the surface lubricity, and the traditional method has the defects of loss of welding performance, reduction of weather resistance and quick reduction of mechanical performance, is not suitable for the standard of TPO waterproof coiled materials and has adverse effect on slip prevention.
