Embodiment approach 1

[0008] Set up the steel mold, place the steel mold on the vibrating frame of the flat vibrating machine, the weight ratio of each component of the concrete is: 35% of 425 grade white cement, 40% of rice grain stone with a volume of 0.1-0.4 cubic centimeters, and The size is 20% of sand of 0.001-0.008 cubic centimeter, 5% of rubber water, fully stir. Spread it in the steel mold, start the vibration machine, the vibration is dense, non-porous, and the surface is smooth. The finished product specification is: 50cm×50cm×2.5cm.

Embodiment approach 2

[0009] Embodiment 2: In order to increase strength and save cost, it can be divided into upper and lower layers, the upper layer is the composition of the present invention, and the lower layer is ordinary concrete plus perlite particles. The production method is:

[0010] Lay the upper layer in the steel mold first, with a thickness of 1.25cmm. The weight ratio of each component is: 37% of 425 grade white cement, 38% of rice grain stone with a volume of 0.1-0.4 cubic centimeter, 20% of sand with a particle size of 0.001-0.008 cubic centimeter, and 5% of rubber water. Stir well . Lay it on ordinary concrete, start the vibrator, and vibrate densely and without holes.

[0011] Lay the lower layer again, i.e. concrete composed of cement, stones, sand, and perlite particles. The weight percentage of perlite particles is about 2%. Start the vibration machine to make it dense and smooth the surface.

[0012] The finished product specification is: 50cm×50cm×2.5cm.

Embodiment approach 3

[0013] Embodiment 3: set up the steel mold, place the steel mold on the vibrating frame of the flat vibrating machine, the weight proportion of each component of the concrete is: 36% of No. 425 white cement, and the rice grain stone with a volume of 0.1-0.4 cubic centimeters 41%, 17% sand with a particle size of 0.001-0.008 cubic centimeters, and 6% rubber water. Stir well. Spread it in the steel mold, start the vibration machine, the vibration is dense, non-porous, and the surface is smooth.

[0014] The finished product specification is: 50cm×50cm×2.5cm.

Abstract

The invention discloses a water proofing heat-insulation room plate of which the constituent element ratio is: white cement 30-45 percent, rice rock 35-45 percent, sand 15-25 percent, glue 3-8 percent. Blend the raw material to pasty cement and injecting into steel mould placed on plain shaking machine. Polish the surface after shaking to tighten the material. The advantages of the invention are that the production is of fine heat and water resistance, long service life, low cost, non-positioning and incombustible. It can be made into standard product and the construction take no influence from the weather.

Description

technical field [0001] The invention relates to a waterproof and heat-insulating roof panel, especially a roof panel capable of reflecting sunlight. Background technique [0002] At present, building waterproofing and heat insulation are a major problem, and the low-grade existing technology is a building material composed of asphalt, ointment, and felt. The high-end building materials are linoleum, foam board, perlite, and plastic film, all of which must go through multiple processes to complete the construction, and the service life of waterproof and heat insulation is short, generally only valid for 5-8 years. And the waterproof, heat-insulating layer that is laid with the above-mentioned composition building material that contains perlite is degenerated and brittle after several years and turns into powder. If the heat insulation layer is adopted, the project cost is high. Burning cement during construction will produce harmful gas, which not only pollutes the environm...
