Method for waterproof construction using a heat-blocking composition for a paint-film waterproofing technique and using a fiber sheet manufactured using a stitch-bonding technique

Abstract

The present invention relates to a method for waterproof construction using a heat-blocking material for paint-film waterproofing and using a fiber sheet manufactured using a stitch bonding technique, and more particularly, to a method for waterproof construction using a fiber sheet manufactured using a nonwoven stitch bonding technique based on the principle of knitting, which has good workability and adhesiveness due to the use of a fiber sheet which prevents the formation of gas bubbles in a paint-film layer, which does not stretch, and which is easily restored so as to improve the tensile strength of a waterproof layer.

Description

technical field [0001] The present invention relates to the waterproof construction method that utilizes the coating waterproof material that has thermal insulation performance and the fibrous sheet material that stitches to manufacture, more specifically, the present invention relates to will utilize acrylic resin latex, polyurethane acrylic resin, acrylic silicon resin The low-carbon energy-saving coating waterproof material is impregnated with stitch-bonded fiber sheets for waterproofing to prevent the occurrence of air bubbles, and in order to increase the tensile strength of the waterproof layer, the vertical and horizontal tensile strength and physical property deviation are so small that they will not loosen and are easy to restore The fiber sheet has good workability and adhesion, especially the 100% polyester material that is easy to impregnate the waterproof layer and has a textile mesh shape of about 2mm, and is made of non-woven fiber sheet using the stitch-bonding ...

AI Technical Summary

Problems solved by technology

[0007] In particular, the above-mentioned coated waterproof materials such as polyurethane waterproof materials are petrochemical products, and contain a large amount of various unreacted monomers and volatile organic compounds (VOC) and other harmful substances that cause air pollution like polyol TDI. Substances, when released in the atmosphere for a long time, also have the problem of causing extreme damage to the human body

Therefore, after several years of construction, the plasticizer evaporates, and the coating that loses the plasticizer has a problem of carbon disappearance, and in actual construction, there is often a problem of losing reliability in the thickness of the waterproof layer due to excessive competition.

[0008] In addition, the Korean registered patent No. 10-0772329 (Waterproofing and base-layer construction method using thixotropic polyurethane and fiber sheet) uses polyurethane waterproofing material, the most widely used polyurethane waterproofing material in the country as an example, according to the characteristics of polyurethane, only It can only be constructed when the moisture content of the base layer is below 7%, but the waterproof construction is mainly around the rainy season, because there are more leaks in the construction, and the precipitation has increased due to the influence of weather changes such as the El Niño phenomenon, and the rainy season has become longer. In wet conditions, polyurethane waterproofing materials are used before and after the rainy season when waterproofing construction is the most frequent. Due to poor adhesion and poor water vapor permeability on the wet surface, problems such as frequent swelling or swelling of the waterproof layer after construction are the cause of construction defects.

In addition, polyurethane with no water vapor permeability cannot naturally permeate, so a separate degassing facility is required, and there are disadvantages that only professional construction workers can carry out construction, and the construction method is complicated.

[0009] In addition, the above-mentioned polyurethane waterproof technology is toxic because most of the products at home and abroad use low-cost aromatic isocyanate, and the problem of reduced weather resistance due to ultraviolet discoloration, plus water vapor permeability and adhesiveness on wet surfaces Poor, the waterproof layer swells or swells, and the existing waterproof layer must be dismantled and re-constructed during re-construction, which has the problem of excessive life-cycle costs

[0010] In addition, the Korean Registered Patent No. 10-0772329 describes the step of applying a primer (primer) on the entire concrete base layer; after arranging waterproof fiber sheets at intervals of 5-10mm on the primer layer, The step of connecting the intervals with a reinforcing belt to form a fiber sheet layer; the step of coating the thixotropic polyurethane on the fiber sheet layer; the step of spraying an ultra-fast hardening resin on the thixotropic polyurethane to form a coating. , but the fiber sheet construction method for waterproofing is arranged at intervals of 5-10 mm, and the intervals are connected with reinforcing tapes, and in order to solve the problems of water vapor permeability of polyurethane waterproofing and adhesion of wet surfaces, it is necessary to set up water discharge It is a degassing facility for steam, so the construction method is complicated, and it is difficult to obtain physical properties with uniform tensile strength because it is arranged at intervals of 5-10mm
