The use of regenerated low-temp liquid rubber modifier makes it has wide use temp range from minus 40 deg.C to 100 deg.C and low cost and may be used in roofing, underground building, water pool, warehouse, cold storage and other waterproofing engineering.
Description
The present invention relates to a kind of water-proof material for building, be specifically related to a kind of hot-melting type superpolymer cryogenic liquid regenerated-rubber water-proofing material and preparation method thereof.
For a long time, the waterproof of cement works roofing and the waterproof, seepage control of underground works are ubiquitous technical barriers, and all are not well solved always.In recent years, along with the developing rapidly of construction industry, people's continuous exploration and practice, the high polymer waterproof material of development and development of new has become the developing direction of current water-proof material industry.But up to now, generally the water-proof material of Cai Yonging is pitch and modifying asphalt, and the warm area scope that the former adapts to is little, and is easily aging, and poor heat resistance is easily trickled, bubbled crisp, the poor flexibility of low temperature; Though the every performance of the latter all is better than the former, and is also not ideal, and adopt the higher polymkeric substance of price such as styrene-butadiene rubber(SBR), chloroprene rubber, SBS, SBR, APP Atactic Polypropelene to make properties-correcting agent, product cost height is difficult to apply.
The objective of the invention is to overcome the deficiencies in the prior art, providing a kind of is the hot-melting type superpolymer cryogenic liquid regenerated-rubber water-proofing material of properties-correcting agent with the cryogenic liquid regenerated rubber, this material had both kept advantages such as asphalt waterproofing, antiseepage, overcome the shortcoming that pitch is cold short, heat is dropped down again, had good low temperature flexibility, thermotolerance, extensibility, cohesiveness and resistance to deterioration.
Hot-melting type superpolymer cryogenic liquid regenerated-rubber water-proofing material of the present invention is made up of following each component, and wherein the configuration proportion of each component is: (weight %)
10# petroleum pitch 13-15
6# petroleum pitch 4-6
Cryogenic liquid regenerated rubber 25-28
Reinforcing filler 48-52
Plastic waste 3-7
Vulcanizing agent 0.5-1
But described reinforcing filler talcum powder or carbon black or kaolin or graphite or xylogen or shellac or resol or polystyrene; Vulcanizing agent is ultra-fine sulphur; Plastic waste is a polyethylene.
The preparation method of hot-melting type superpolymer cryogenic liquid regenerated-rubber water-proofing material of the present invention is:
Accurate according to the above ratio each component of weighing, and the order of pressing pitch, cryogenic liquid regenerated rubber and plastic waste, reinforcing filler, vulcanizing agent adds heated polymerizable in the polymeric kettle with each component, the rotating speed of the agitator in the polymeric kettle is 18-50 rev/min, polymerization temperature is controlled at 140-240 ℃, after polymerization 5-9 hour, resulting polymers is milled through two roll-in refining machines and is promptly got product after mixing, and the speed of two roll-ins refining machine is 32-55 rev/min.
The present invention compared with prior art has the following advantages:
1, the warm area scope of Shi Yinging wide-40-100 ℃, non-foaming under the high temperature, do not trickle, under the low temperature not crisp firmly, do not ftracture;
2, extensibility, adhesive property are good;
3, anti-aging energy property is strong, shelf life is long;
4, because employing cryogenic liquid regenerated rubber is made properties-correcting agent, thereby the product cost is low;
5, applied widely, can be used for waterproofing works such as various building roofs, underground installation, pond, warehouse, freezer.
Hot-melting type cryogenic liquid regenerated-rubber water-proofing material of the present invention can adopt the single ply waterproofing structure when using on engineering, construction can require according to the length in engineering work-ing life to deal with on the merits of each case, general work-ing life is 5-10's, material usage is 4-6kg for every square metre, coat-thickness is 2-6mm, and construction temperature is 180-190 ℃, like this, material easily infiltrates in the crack of fabric structure, thereby reaches the excellent waterproof effect.
