Problems solved by technology

[0003] Among them, the coating film waterproofing process is a method of repeatedly coating a liquid-type waterproofing agent, which has the following problems: when the ground is not smooth due to the fluidity of the liquid itself, the thickness of the waterproof layer is also uneven, and it is difficult to form a coating film. In order to prevent this phenomenon, it is necessary to accompany the ground smoothing process before waterproofing construction
[0008] In order to solve the above problems, the present inventor has developed a method for preparing an adhesive waterproof sheet and a waterproof sheet prepared therefrom through Korean Authorized Patent No. 10-0907647 (2 companies such as Heungshinenc Co., Ltd.), which is due to the fact that there are no One side of the woven fabric uses an adhesive to bond the sheet attachment process of the asphalt sheet, so it is found that there are environmental hazards and difficulties in the production process, as well as excessive softness and weight problems of the asphalt sheet, and sheet and non-woven Durability is still reduced due to poor

Embodiment

[0055] With respect to 70% by weight of water, 30% by weight of organic acid-based monomers and metal hydroxides were mixed and reacted to prepare an organic acid-based metal salt aqueous solution, and then MBAA crosslinking agent 5 was added based on the above-mentioned organic acid-based metal salt aqueous solution. % by weight, after the gelled substance is prepared by chain polymerization, 200 g / m is bonded to one side of the PVC sheet in the molten state 2 Weighed short-fiber non-woven fabric net and extruded to prepare PVC sheet, impregnated the above-mentioned gelling substance on the above-mentioned non-woven fabric to prepare an acrylic waterproof sheet with an adhesive layer having a thickness of about 2mm , by formulating the following [Table 1], the above-mentioned organic acid-based monomers and metal hydroxides were prepared. Wherein, in embodiment 4, based on the total weight of the gelled substance, about 20% by weight of moisturizing fillers (ethylene glycol, ...

experiment example

[0059] Based on the adhesive acrylic waterproof sheet of the above-mentioned examples, etc., a frame with a size of 500×500 mm was produced under the same conditions as the site construction. In this regard, physical properties such as elongation, tensile strength, and adhesion strength were measured several times, and the average values ​​of the test results are shown in [Table 2].

[0060] [Table 2]

[0061]

[0062] As shown in [Table 2] above, comparing the test results of Examples 1 to 4 and Comparative Example, the acrylate gelling substance of the present invention is mixed with an appropriate amount of organic acid-based monomers and metal hydroxides. prepared by a type of polymerization reaction, thus exhibiting excellent physical properties in all test items such as elongation, tensile strength, and adhesion strength. In particular, Example 4, even though it contains a large amount of moisturizing filler, compared In Example 2, there is little difference in physi...

Abstract

The invention relates to a cohesive acrylate waterproof sheet and a waterproof process method using the same. A non-woven fabric is bonded to one surface of a molten PVC or EVA sheet, and the non-woven fabric bonded to the PVC or EVA sheet is impregnated with an acrylate to form an adhesive layer. The acrylic acid ester comprises 90-99 parts by weight of one or more organic acid-based monomers selected from the group consisting of acrylic acid, methacrylic acid, itaconic acid, and maleic anhydride, based on 65-75% by weight of water; 1-10 parts by weight of one or more inorganic bases selected from the group consisting of monovalent metal hydroxides consisting of sodium hydroxide, potassium hydroxide and lithium hydroxide or divalent metal hydroxides consisting of magnesium hydroxide and calcium hydroxide are mixed and reacted to prepare an aqueous solution of an organic acid-based metal salt; 1-10 wt% of a cross-linking agent is added, and a gelatinized substance is prepared through a chain polymerization reaction.

Description

technical field [0001] The present invention relates to an adhesive acrylate waterproof sheet and a waterproof process using it. More specifically, it relates to bonding a non-woven fabric to one side of a melted PVC or EVA sheet, and impregnating the non-woven fabric with acrylate to Form an adhesive layer, reduce the process of coating adhesive, and be environmentally friendly. Therefore, not only the waterproof function of the surface of the concrete structure is excellent, but also the separation phenomenon of the waterproof layer itself is improved, and the heat insulation effect and corrosion of structural materials and An adhesive acrylic waterproof sheet having excellent crack resistance and easy construction, and a waterproofing process using the same. Background technique [0002] Generally speaking, in order to block the inflow of rainwater and groundwater, and to prevent the structure from cracking or durability reduction, buildings and civil structures must be w...
