Waterproof, sun-proof and heat-insulating building material protection brick and preparation method thereof

Abstract

The invention relates to the technical field of building materials, in particular to a waterproof, sun-proof and heat-insulating building material protection brick and a preparation method and application thereof. The waterproof, sun-proof and heat-insulating building material protection brick at least comprises the following components in parts by weight: 30-60 parts of cement, 70-100 parts of aheat-insulating material, 25-45 parts of an acrylic emulsion, 5-25 parts of a polyurethane emulsion, 0-3 parts of a release agent and 5-15 parts of a filler. The prepared protection brick is light inweight, cannot damage the bearing structure of a building, is good in bearing performance, and can bear multiple people to walk randomly at the same time; the waterproof, sun-proof and heat-insulatingbuilding material protection brick is laid on the top of a building, can form an integrated waterproof barrier, has good heat-insulation performance, can completely block exposure to the sun in midsummer and invasion of cold air in winter, improves indoor comfort, and saves cooling and heating cost.

Description

Technical field [0001] The invention relates to the technical field of building materials, in particular to a waterproof, sun-proof, and heat-preserving building material protective brick, and a preparation method and application thereof. Background technique [0002] At present, in my country's industrial and civil construction, concrete flat roofs are commonly used, and the roof is above the flat roof. The well-known roof structure is a multi-layer structure to prevent rainwater leakage and sun exposure in summer. According to the book "Mixed Structures of Civil Houses" published by China Construction Publishing House, flat roof waterproofing mainly includes coil waterproofing and rigid waterproofing. The construction process of the coiled material waterproof layer is complicated, the construction conditions are demanding, and the environment is polluted during construction. The coiled material is easy to age, crack, bulge, high cost, and short life; the rigid waterproof struc...

Problems solved by technology

[0003] With the development of society, people's requirements for living comfort are getting higher and higher. In order to ensure the effect of residential heat insulation, heat insulation bricks are needed. The waterproof effect of heat insulation bricks currently used is poor, resulting in heat insulation The bricks have a short service life and will be damaged when in contact with water for a long time, which increases the cost of using the insulation bricks and reduces the practicability of the insulation bricks

The traditional heat insulation method is to lay a layer of cement prefabricated board overhead on the roof, and form an air layer between the cement prefabricated board and the roof, and block the heat from entering the room through the air layer. Although this method can play a certain role Thermal insulation

However, due to the heavy weight of the cement prefabricated board, the load-bearing burden of the building is increased. In fact, the air itself is hot on a hot day, so its heat insulation effect is not ideal.

At present, heat insulation bricks are used instead of prefabricated panels, and the effect is better than that of prefabricated panels. However, because this kind of insulation brick uses flammable materials as the insulation layer, it is not suitable for application.
