Waterproof protective material and production process thereof
Technical Field
The invention relates to the technical field of waterproof materials, in particular to a waterproof protective material and a production process thereof.
Background
The concrete protective layer of the planted roof or the roof is laid above the waterproof layer to protect the waterproof layer from being damaged.
In the prior art, a concrete protective layer is arranged on the waterproof layer to protect the waterproof layer from being damaged. The existing concrete protective layer has the following defects: first, the existing protective layer is formed by casting concrete, so that the consumption of concrete is large and the manufacturing cost is high. Secondly, the concrete protective layer can not be constructed in the weather of low temperature (winter) and heavy rain and heavy snow, and the plastic drainage plate can be constructed after the concrete protective layer is dried, which can cause certain influence on the construction period. Thirdly, the concrete protective layer is not easy to seep water and can not drain water, and the water leaked to the concrete protective layer by the drainage plate is difficult to drain.
Therefore, how to provide a waterproof protective material which has the function of protecting the waterproof layer, can save the using amount of concrete, reduce load and save construction cost, is particularly suitable for accessible roofs and inaccessible roofs, and has good hydrophobicity and a production process thereof are one of the technical problems to be solved in the field.
Disclosure of Invention
In view of the above, the present invention provides a waterproof protective material and a production process thereof. The purpose is to solve the above-mentioned deficiency and offer.
In order to solve the technical problems, the invention adopts the following technical scheme:
the waterproof protective material consists of a rubber particle layer and a rubber modified asphalt binder or an aqueous emulsion adhesive filled in the rubber particle layer.
Preferably, the rubber particle layer is 3-8 mm small rubber particles.
Preferably, the rubber modified asphalt binder comprises the following raw materials in parts by weight:
preferably, the aqueous emulsion adhesive comprises the following raw materials in parts by weight:
20-30 parts of water-based emulsion
10 portions of cement
50 parts of medium sand.
Meanwhile, the invention also provides a production process of the waterproof protective material, which comprises the following steps:
1) mixing and stirring the small rubber particles, the rubber modified asphalt binder or the aqueous emulsion adhesive for 1 hour at low temperature to obtain a mixed raw material;
2) putting the mixed raw materials obtained in the step 1) into a mould, compacting and cooling to form a permeable rubber plate with gaps, namely the waterproof protective material.
Preferably, the low temperature in step 1) is below 50 ℃.
Preferably, the sizes of the water discharge protection material prepared in the step 2) are as follows: the width is 60cm, the length is 60cm, and the thickness is 1-2 cm.
Compared with the prior art, the invention has the following technical effects:
1) the size of the water discharge protective material (the permeable rubber plate with the gap) prepared by the invention can be cut according to the thickness or size of the water discharge protective material according to the site construction requirement, and the water discharge protective material has better compression resistance and permeability than a concrete protective layer, the compression strength is more than or equal to 100KPa/mm, the impact resistance is 0.5 kg.m, the water discharge protective material is not permeable, and the permeability coefficient is not less than 1.0 multiplied by 10 < -2 > cm/s;
2) compared with the existing concrete protective layer, the waterproof protective material can adopt a factory prefabricated production mode, can also be constructed in severe weather, and saves the construction period. Or heating, stirring and laying on site; because the rubber protective layer has certain thickness and elasticity, the waterproof layer can be protected when the rubber protective layer is laid, and after the rubber protective layer is laid, a concrete protective layer does not need to be laid, so that the using amount of concrete is saved, the load is reduced, the engineering cost is saved, and the waterproof layer is particularly suitable for roofs with people and roofs without people. Because the rubber protective layer has certain elasticity, the rubber protective layer is suitable for a planting roof of backfill, and sharp stones, waste residues and the like in the backfill cannot cause damage to the rubber protective layer. The water storage layer has a certain gap, rainwater can enter the drainage pipeline along the gap to form organized drainage, and the water storage layer cannot be formed by water stored in the protective layer.
