Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of waterproofing and fireproofing construction of buildings such as roofs, external walls, or floors, and a waterproofing and fireproofing ground treatment agent therefor.

In general, waterproofing of the roofs of buildings is performed using a laminated structure based on synthetic rubber such as butyl rubber, or vulcanized or unvulcanized natural rubber, and the surface of which is coated with concrete mortar. However, since the base rubber material is not nonflammable, there is a problem that if the concrete mortar is coated with a large amount of violet, the building law will not apply. Although it is attached, there is no rmvt on top of the waterproof and water rubber sheet.
Therefore, it was often inconvenient to apply coating with a lath net or the like.

This invention was made in layers based on the points mentioned above, and a waterproofing agent is applied to the base material such as rubber material, concrete, wood, etc. from above and bonded. The object of the present invention is to provide a method for waterproofing and fireproofing buildings by applying a cationic synthetic resin mortar as a binder to form a thin layer of waterproofing material with excellent adhesive strength.

In addition, the present invention aims to improve the adhesion between a desired base and a cationic synthetic resin mortar by blending a pigment or a thickener, or both, with hexane or other organic bath agent. The purpose of the present invention is to provide a waterproof and fireproof base treatment agent.

By the way, the cationic synthetic m-lipid mortar used in this invention is 1.
Preferably, it is a mortar composition based on the cationic/vinyl acetate copolymer emulsion blend of the invention of No. 112998.

That is, the base material of the cationic synthetic resin mortar of the present invention has the general formula (wherein, tl is alkylene or hydroxyalkylene, R1 and S are hydrogen or alkyl, R3 and R4 are alkyl, and X is an inorganic A cationic ethylene-Me vinyl copolymer having a cationized resin containing 1$Ii or two or more cationic groups selected from the group of cationic groups (al, (bl, tc) represented by (or organic anions) This is a cationic ethylene-acetic acid vinyl copolymer emulsion formulation based on Emulsion/.

Further, the waterproof and fireproof base treatment agent according to the present invention is constituted by distributing a pigment or a thickener, or both, to a bath agent such as hexane, perchlorethylene, 1.1.l-trichlorethylene, or ethylene chloride. In particular, due to the evaporation of the solvent, the coated surface becomes the same as the uncoated surface, making it impossible to confirm whether the coating has been applied or not. It is possible to clarify the difference between the coated surface and the uncoated surface to facilitate subsequent construction.

An embodiment of the waterproofing and fireproofing construction method for buildings according to the present invention will be described below, together with a specific example of the waterproofing and fireproofing base treatment agent.

A base 2 made of vulcanized or non-vulcanized rubber is coated on the surface of the paste 1 with a coating layer of a waterproofing agent. 3 is a cationic synthetic resin mortar coating layer and a cationic ethylene-vinyl acetate copolymer emulsion or d88
It has a structure in which a R, type copolymer emulsion compound and desired cement mortar, aggregate, etc. are blended.

Next, the structure of each coating layer described above will be explained.

0.3 1 In the above composition, various pigments can be used depending on the coloring, and the thickener can be arbitrarily selected, such as methyl cellulose or urethane resin, and both solvents can be used. The presence or absence of coating is visually confirmed by the presence or absence of color or viscosity. In addition, "compounds" indicated as "other" refer to dispersants or preservatives for effective dispersion of pigments.

Next, the composition of the cationic synthetic resin mortar coating 1- will be described.

This basic structure consists of groups of cationic groups (a) and (b) represented by
.

A cationic ethylene-vinyl acetate copolymer emulsion having a cationized resin containing one or more cationic groups selected from (c) is used as a base, and this base is combined with a thickener and freeze-thaw stability A cationic ethylene-vinyl acetate copolymer emulsion compound containing one or more of additives, rust inhibitors, preservatives, antifoaming agents, emulsifiers, or dispersants together with water is prepared in advance into a cement-based copolymer. Obtained by mixing with mortar.

A, in the above formula, R1 is alkylene or hydroxyalkylene, R and 3 are hydrogen or alkyl, and
represents alkyl, and X represents an inorganic or organic anion.

Cement-based mortar refers to cement with 0 to 5 parts of aggregate added, and cement refers to hydraulic cement such as Portland cement, gypsum,
Refers to air-hard cement such as lime.

The details of the concrete example of the cement-based mortar are the same as those shown in the invention of Japanese Patent Application No. 112999/1987 filed by the present applicant, so the explanation thereof will be omitted.

The waterproof and fireproof base treatment agent and cationic synthetic resin mortar material having the above-mentioned specific configuration are prepared by first applying the waterproof and fireproofing F base treatment agent to the surface to be coated, for example, the base 1, and then applying the cationic synthetic resin mortar material. The construction is done by photon coating by applying it in layers.

The hardness of the cationic synthetic resin mortar material can be freely changed by changing the amount of mortar mixed, and furthermore, a multilayer cement mortar layer can be formed on the surface by coating means.

In addition, when the adhesive strength of the above example was tested,
It was possible to obtain a very strong tensile strength corresponding to 1cIlfi 10.5# to 121p. (However, using a Kenken-type measuring machine) Although the embodiments of this invention have been described above, roofs,
When forming a cationic synthetic resin mortar layer on the surface of an area that requires waterproofing, such as an exterior wall, a waterproofing agent is applied in advance to the butyl rubber base or wood that constitutes the base, and then the coating surface is coated with a waterproofing agent. Since the cationic synthetic resin mortar layer is formed, the coating amount of the layer is small, and the non-flammable effect can be sufficiently enhanced to form a high-quality construction surface, and the waterproof and fireproof base treatment agent has a kind of binder effect, so it can be bonded. It has many effects such as high sexual performance.
