Embodiment 1

[0018] Embodiment 1, the formula that adopts and proportioning and step are as follows:

[0019] Waterproof and thermal insulation building materials are composed of the following components (weight ratio):

[0020] Cement: 1 Sand: 2.5

[0021] Expanded vitrified microbeads: 0.1 Water repellent: 0.9

[0022] Polystyrene particles: 0.1 rubber powder: 0.02;

[0023] Preparation:

[0024] Step 1: Determine the dosage of cement, sand, expanded vitrified microbeads, rubber powder, polystyrene particles and waterproofing agent according to the weight ratio requirements;

[0025] Step 2: Mix the above materials together, dry and stir evenly;

[0026] Step 3: Add water repellent and stir evenly to obtain the mixed slurry;

[0027] Step 4: Coating the mixed slurry obtained in the above step 3 on the top surface of the building to form a first coating;

[0028] Step 5: After waiting for the first coating layer in Step 4 to dry, coat the mixed slurry obtained in Step 3 above on the...

Embodiment 2

[0038] Adopt the formula and proportioning of above-mentioned embodiment 1, step is as follows:

[0039] ①Mixing: Manual stirring should be used when the construction area is small, and mechanical stirring can be used when the construction area is large. Mix cement, sand, expanded vitrified microbeads, polystyrene particles, and rubber powder together for dry stirring. After uniformity, add water repellent solution according to the mixing ratio requirements, and then perform wet stirring. It can be used after it is even.

[0040] ② Spreading: Spread the above-mentioned materials that have been stirred evenly on the roof, smooth it with a scraper, and vibrate and compact it with a vibrator according to the standard (virtual square: real square = 1:0.8)

[0041] ③Compact and receive light. The compaction and lightening shall not be less than three times.

Abstract

The invention relates to a waterproof, heat preservation and thermal insulation building material and a preparation method thereof, which are used for the building field. The building material comprises the following components according to the weight ratio: 1 of cement, 2.5 of sand, 0.1 of expanded and vitrified small ball, 0.9 of water repellent, 0.1 of polystyrene particles and 0.02 of rubber powder; the preparation method comprises the following steps: mixing the materials together and dryly and evenly stirring; adding the water repellent and evenly stirring to obtain mixed slurry; coatingthe obtained mixed slurry on the top floor of a building to form a first coating; after the first coating is dried, coating the mixed slurry on the first coating to form a second coating; and coatingthe mixed slurry to form a third coating after the second coating is dried. The waterproof, heat preservation and thermal insulation building material replaces the multi-layer structure of the priorart, is simplified into three layers, meets the technical requirement to the top floor of the building and achieves the effects of water resistance, heat preservation and thermal insulation of the multi-layer structure; and the preparation method is simple, and superior to the preparation and construction method for the multi-layer structure, simplifies the process and improves the efficiency.

Description

technical field [0001] The invention relates to a waterproof thermal insulation building material used in the construction field and a preparation method. Background technique [0002] Now the roof surface of buildings is generally a multi-layer structure, in order to achieve the effect of waterproof and thermal insulation. However, the construction period is long, and the procedures are many and complicated. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to improve the shortcomings of the prior art, and provide a waterproof thermal insulation building material and a preparation method. [0004] In order to achieve the above object, the present invention adopts the following design scheme: the waterproof thermal insulation building material is made up of the following components (weight ratio): [0005] Cement: 1 Sand: 2.5 [0006] Expanded vitrified microbeads: 0.1 Water repellent: 0.9 [0007] Polystyrene particles: 0.1 rubber powder: 0.02;...
