Waterproof building material based on self-repairing capability and manufacturing process

Abstract

The invention relates to the technical field of waterproof building materials, and discloses a waterproof building material based on self-repairing capability and a manufacturing process. The waterproof building material comprises the following raw materials in parts by weight: 30-40 parts of a pure acrylic polymer emulsion, 6-12 parts of modified carbon fiber powder, 12-16 parts of nitrile rubber, 1.5-2.0 parts of a polyurethane emulsion, 2.5-3.5 parts of a thickening agent, 1.0-1.5 parts of triethanolamine, 3-7 parts of organosiloxane and 4-8 parts of inorganic black iron oxide nanoparticles. By adding an in-situ emulsification liquid, a repairing agent, a defoaming agent, an active agent, the organic siloxane, the inorganic black iron oxide nanoparticles and n-propyltrimethoxysilane, an internally coated magnetic curing agent material is agglomerated due to mutual attraction among magnetic particles, so the contact area of the material and a curing agent is effectively increased, the curing rate of the material is increased, the self-repairing process of the waterproof building material is effectively improved, rapid and effective self-repairing of the material is achieved, and the integrity and the service life of the waterproof building material are cooperatively guaranteed from multiple dimensions.

Description

technical field [0001] The invention relates to waterproof building materials, in particular to a waterproof building material based on self-repairing ability and a manufacturing process. Background technique [0002] Waterproof material is the enclosure structure of the building to prevent the penetration of rainwater, snow water and groundwater; to prevent the erosion of moisture, steam and other harmful gases and liquids in the air, and to prevent the seepage of water supply and drainage in the separation structure. Infiltration, leakage and erosion materials are collectively referred to as materials that prevent rainwater, groundwater, industrial and civil water supply and drainage, corrosive liquids, and moisture and steam in the air from intruding into buildings. The parts of buildings that need to be waterproofed are mainly Roofs, walls, floors and basements. [0003] Waterproof building material coating is a kind of material, which can be coated on the surface of ob...

Problems solved by technology

[0004] The purpose of the present invention is to solve the shortcomings in the prior art, such as: the structural strength of the coating film is poor, so that its service life is still at a low stage, and its function is relatively single, and its weather resistance is not good. When a small tortoise crack occurs due to factors, it cannot be repaired in a font. When people find it, the crack size often becomes large and the repair cost is high. A waterproof building material and manufacturing process based on self-repair ability is proposed
