Conventionally, when applying mortar to the exterior wall of a building, a waterproof layer is formed on a wooden board such as plywood, and then resin cement or various types of lightweight bone are applied on top of the waterproof layer in order to save labor and shorten the construction period. Mortar base materials with a cement layer added with wood have come into widespread use.

This type of mortar base material has a strong waterproof layer formed on the wooden substrate, and during construction, it has excellent adhesion between wood composite boards or with top coat mortar, etc., and is easy to install, and has sufficient waterproofing. Since there is no sealant for wood composite boards that has the properties of waterproofing, there remains a problem in waterproofing the joints during construction.

The present invention was made to solve the various problems mentioned above, and provides a sealant composition that has many advantages and is used for waterproofing wood composite boards used as a base material for mortar coating. This product eliminates the above drawbacks by blending a filler containing a certain amount of sandy aggregate with an aqueous one-component synthetic resin latex such as acrylic, styrene-butadiene, or butyl rubber. be.

In other words, conventional sealants are mainly used for the joints of cement, tiles, etc., and because the material of the filling part is relatively simple, they are used to improve the dispersion of the filler and fill even the smallest voids. Aiming to achieve this goal, the technical focus was on making the entire filler particles finer to facilitate their dispersion and filling.

However, if the particles of the filler are simply made finer, there is a problem that cracking or peeling may occur when the sealant dries after application, and it is difficult to seal parts such as wood composites where various compositions are laminated. There are naturally limitations on the synthetic resin that can be used, and the concept of simply using a synthetic resin material to compensate for the cracking and peeling described above is not sufficient.

Rather, the present invention achieves an optimal composition as a sealing material for wood composite boards by combining relatively coarse and fine filler particle sizes. 50 to 250 parts by weight of the filler is mixed with 100 parts by weight of the one-component synthetic resin latex, and 20 to 50% by weight of the filler is sandy aggregate with a particle size of 150 to 500 microns.

The aqueous one-component synthetic resin latex used in the present invention includes acrylic ester latex, styrene-butadiene latex, butyl rubber latex, and the like. Calcium carbonate, talc, clay, etc. are usually used as fillers added to these aqueous one-component synthetic resin latexes, and these can also be used in conjunction with the fillers used in the present invention. However, the effect of the present invention is that sandy aggregate
50 to 250 parts by weight of a filler containing 20 to 50% by weight per 100 parts by weight of an aqueous one-component synthetic resin latex.
It is obtained by adding parts by weight. As the above-mentioned sandy aggregate, natural sand such as silica sand and standard sand is most suitable. Furthermore, in order to obtain the effects of the present invention, the particle size and amount of the natural sand etc. in the filler are particularly important. Previously, calcium carbonate talc and clay used for this type of application had a particle size of 100.
When a sealing composition consisting only of these fillers is used in the application of the present application, it is difficult to obtain sufficient adhesion to wood, cement, cement mortar, etc., since it is a fine powder of less than a micron size. A sealing composition with good adhesion and good performance can be obtained by mixing 20 to 50% by weight of a known filler with natural sand or the like having a particle size of 500 to 500 microns. The reason for this is not clear, but because these natural sands have large particle sizes and hardness, they can be filled into the voids of porous and highly water-absorbing materials such as plywood, cement, and cement mortar. It is thought that it is possible to form a filled layer with increased hardness and high hardness, and also to form a sealing layer with less volumetric shrinkage after drying and curing.

It is also important that the proportion of natural sand etc. in the filler is 20 to 50% by weight; if it is less than 20%, the adhesive strength to wood, cement and cement mortar will decrease, resulting in peeling of the sealing layer after construction.
If the amount is more than 50% by weight, the stability as a sealing composition is lost and the inner wall of the extrusion plunger of the caulking gun is abraded.
