Problems solved by technology

[0004] At present, the most common concrete insulation board has been widely used in various buildings, but the concrete insulation board has large internal pores, high water absorption, moisture expansion, drying shrinkage, and loose surface, which leads to cracking and hollowing on the surface of the insulation board. Even falling off, water seepage in the wall and other phenomena will not only seriously shorten the service life of the insulation board, but also lead to a significant reduction in insulation performance

Embodiment 1

[0043] see figure 1 , a preparation process of an oil-bleeding type anti-seepage building insulation board, comprising the following steps:

[0044] S1. Weigh the following raw materials in parts by weight: 15 parts of Portland cement, 10 parts of fly ash, 10 parts of polypropylene fiber, 5 parts of expanded perlite particles, 4 parts of silicon carbide, 6 parts of functional particles, 10 parts of Inorganic colloid, 4 parts of calcium stearate, 3 parts of foaming agent, 0.5 part of water reducing agent and 20 parts of water;

[0045] S2. Take the above-mentioned raw materials and add them to the mixer for stirring. After uniform mixing, pour them into the mold. During the pouring process, a plurality of oil bleeding anti-seepage balls 1 are pre-embedded in time, and the oil bleeding anti-seepage balls 1 are pre-embedded to maintain oil bleeding. The anti-seepage ball 1 is 1-3cm away from the inner and outer surfaces of the finished insulation board without sinking;

Abstract

The invention discloses a preparation process of an oil bleeding type anti-seepage building insulation board, belongs to the technical field of building insulation, and aims to improve the insulationperformance and crack resistance of a concrete insulation board by improving the raw materials of the concrete insulation board and fill hydrophobic and oleophylic organic bentonite to perform overallphysical modification on the insulation board, so that the anti-seepage performance of the insulation board is improved. In addition, a plurality of oil bleeding anti-seepage balls which are uniformly distributed are embedded in the position, which is close to the surface, of the interior of the insulation board in advance, the oil bleeding action in the oil bleeding anti-seepage balls is triggered by sensing the water seepage phenomenon, and oil wrapping belt water-repellent microspheres are forced to carry out reverse filling along a water seepage path. By means of the action that the water-repellent microspheres decompose when encountering water, permeation water is repelled, and oil is dispersed through the oleophylic characteristic of the insulation board at the same time, so that seepage prevention treatment and blocking treatment are conducted on a seepage area, permeation water can be effectively prevented from further diffusing and going deep, finally, seepage prevention protection of the insulation board is achieved, and the heat preservation service life of the insulation board is prolonged.

Description

technical field [0001] The invention relates to the technical field of building heat preservation, and more specifically relates to a preparation process of an oil-bleeding anti-seepage building heat preservation board. Background technique [0002] Exterior wall insulation board, also known as horizon building exterior wall decoration integrated board. It is made of composite materials such as polymer mortar, glass fiber mesh cloth, flame-retardant molded polystyrene foam board (EPS) or extruded board (XPS), and functions as an external wall insulation board. Factory production, on-site bonding construction, is the preferred material to meet the current energy-saving needs of housing construction, improve the thermal insulation level of industrial and civil building exterior walls, and is also the preferred material for energy-saving renovation of existing buildings. Used for high-rise exterior walls, indoor shopping malls, and industrial equipment, it has the advantages o...
