Description
Technical field
The present invention relates to a kind of preparation for preparing roofing phase-change accumulation energy slurry, specifically a kind of room cool in summer and warm in winter
The compound method of face waterproof phase-change accumulation energy slurry.
Background technology
The current residential building building of China, cement roof is in the majority, and cement roof generally there are two large problems, one is waterproof is asked
Topic, the often leak because poorly sealed between prefabricated board seam；The second is the heat radiation problem of cement, summer, The hot sun is high in the sky, water
Mud plate by heat radiation to top layer room, just as among food steamer, be radiated severe cold in top layer room by winter cold jelly, cement plate,
Just as in ice cell.Resident to this general house top layer has an intimate knowledge.It is general to be applied using pitch in order to prevent roof leaking
Apply, but through exposing to the sun and rain, ageing of asphalt starts roof leaking again soon, is repaired again, so goes round and begins again, and unbearably it is tired of.It is right
In the heat radiation of cement roof, conventional is the method for taking air buffer, i.e., with brick into some in length and breadth short on roofing
Small partition wall, covers waterproof thing, such as slabstone, asbestos shingle, cement plate again above, once but roofing leak, again by covering
Raise, brick baffle is destroyed, be very much inconvenient.A solution that the present invention is proposed aiming above mentioned problem.
The content of the invention
The purpose of the present invention, aiming at cement roof leak and heat transfer problem, and a solution for proposing, that is, match somebody with somebody
A kind of phase-change accumulation energy slurry is made, for roof waterproof, while reaching indoor purpose cool in summer and warm in winter.
A kind of compound method of roof waterproof phase-change accumulation energy slurry cool in summer and warm in winter of the present invention, it is characterized in that being pressed by following raw materials according
Weight proportion is formulated：
