[0003] However, the traditional composite color steel plate uses an adhesive to composite the core material between the face plate and the bottom plate, which has the disadvantages of insufficient side strength, insufficient bonding strength between the face plate, the bottom plate and the core material, and insufficient mutual docking of the composite color steel plate.
Moreover, because the outer side of the color steel plate is sprayed with plastic and paint for a long time, it will peel off. When the coating is peeled off, the inner steel plate is prone to rust, which affects the structural strength, making the ability to resist wind, snow and pressure in winter weak.
Moreover, the general color steel plate simple house is relatively weak in thermal insulation and sound insulation performance, especially for the simple house on the construction site. Famous workers cannot sleep comfortably, and a good rest environment has been challenged, which will greatly affect the work efficiency of migrant workers during the day

Embodiment 1
[0034] A roof cover plate for a simple house, the preparation method comprising:
[0035] (1) Asbestos fiber pretreatment
[0036] Weigh 15kg of asbestos fibers, add 9kg of water-based polyurethane emulsion (purchased from Taixing Zhongfang Auxiliary Factory, brand name PU328-9K, solid content 33%) to it, stir and mix evenly, and let stand for 2h to obtain mixture I;
[0037] (2) Weigh 40kg of cement (purchased from Anhui Chaodong Cement Co., Ltd., Dongguan brand, cement strength grade 32.5) and 100kg of yellow sand (purchased from Lingshou County Hengchuan Mineral Products Processing Plant, sand particle size distribution 10-20 order), add 350kg of water to be reconciled into cement mortar, the mixture I in the step (1) is added and stirred evenly, then add 8kg zinc oxide whiskers, continue to stir to obtain the mixture II,
[0038] (3) Spread half of the mixture II on the plastic cloth on the working table, smooth it, let it stand for 15 minutes, and then spread the carbon ...
Embodiment 2
[0041] This embodiment is the same as the preparation method of the house cover in Example 1, the difference is that the pouring amount is controlled so that the total thickness of the house cover is 8mm, wherein the thickness of the main body layer is 3.81mm, and the thickness of the carbon fiber cloth layer is 0.38mm .
Embodiment 3
[0043] This embodiment is the same as the preparation method of the house cover in Example 1. The difference is that the pouring amount is controlled so that the total thickness of the house cover is 8 mm, wherein the thickness of the main body layer is 3.72 mm, and the thickness of the carbon fiber cloth layer is 0.56 mm. .

Abstract
The invention relates to the technical field of building plates, in particular to a roof cover plate for a makeshift house. The roof cover plate for the makeshift house comprises two main body layersand a carbon fiber cloth layer clamped between the two main body layers, and the main body layers are composed of cement, yellow sand, asbestos fiber, inorganic whiskers in a compound ratio mode; thethickness ratio of the main body layers and the carbon fiber cloth layer is 1:(0.05-0.2); and the asbestos fiber is modified by 0.5-0.9 times amount of an aqueous polyurethane emulsion. According to the roof cover plate for the makeshift house, the integral strength is enhanced through the structural design of the two main body layers and the carbon fiber cloth layer between the two main body layers; at the same time, the addition of the inorganic whiskers in the main body layers is matched with the asbestos fiber to further enhance the structural strength of the roof cover plate, and the strength requirement of the roof cover plate is met; and damage caused by the asbestos fiber is significantly reduced after the asbestos fiber is modified, and the roof cover plate can replace asbestos tiles which are low in cost and harmful to be used for roof construction of the simple house.
Description
technical field [0001] The invention relates to the technical field of building boards, in particular to a roof cover board for a simple house. Background technique [0002] The simple house is a kind of temporary building with fast construction speed and wide application. Now it generally adopts light steel frame composite color steel plate structure. Composite color steel plate is a thermal insulation composite maintenance plate formed by combining color coated steel plate or other panels and bottom plates with thermal insulation core material through adhesive (or foaming), which has the advantages of convenient construction, flexible and fast installation, heat insulation and high strength. The advantage of being tall, it is suitable for the construction of side panels and roof covering panels of simple houses. [0003] However, the traditional composite color steel plate uses an adhesive to composite the core material between the face plate and the bottom plate, which h...
