Abstract
Disclosed is a concrete non-cure material for preventing the surface of cement mortar, which maintains contact with said material, from setting or hardening. This invention also discloses a concrete product or concrete structure with surface decorations produced by affixing the concrete non-cure material to the surface of the decorative material or to the inner surface of a form for a concrete molding and production methods therefor.
Claims5
A concrete non-cure material for preventing the surface of cement mortar, which maintains contact with said concrete non-cure material, from setting or hardening:
- wherein said concrete non-cure material is a polymer having a high water absorption which is made from mixing propylene glycol with maleic anhydride and either phthalic anhydride or isophthalic acid, dissolving the resultant unsaturated alkyd into 2-hydroxyethyl methacrylate in a weight ratio of 60 to 40 or 70 to 30, adding 100 ppm of hydroquinone and 5,000 ppm of 6% copper naphthenate into the resultant mixture, mixing 55% methyl ethyl ketone peroxide with the resultant liquid.
A concrete non-cure material for preventing the surface of cement mortar, which maintains contact with said concrete non-cure material, from setting or hardening:
- wherein said concrete non-cure material is a powdered polymer having a high water absorption which is made from mixing propylene glycol with maleic anhydride and either phthalic anhydride or isophthalic acid, dissolving the resultant unsaturated alkyd into 2-hydroxyethyl methacrylate in a weight ratio of 60 to 40 or 70 to 30, adding 100 ppm of Hydroquinone and 5,000 ppm of 6% copper naphthenate into the resultant mixture, mixing 55% methyl ethyl ketone peroxide with the resultant unsaturated polyester resin, and hardening the resultant liquid.
A concrete non-cure material for preventing the surface of cement mortar, which maintains contact with said concrete non-cure material, from setting or hardening:
- wherein said concrete non-cure material is made from coating a surface of sand particles or gravel with a polymer having a high water absorption and hardening said coated sand particles or gravel, said polymer having a high water absorption is made from mixing propylene glycol with maleic anhydride either phthalic anhydride or isophthalic acid, dissolving the resultant unsaturated alkyd into 2-hydroxyethyl methacrylate in a weight ratio of 60 to 40 or 70 to 30, adding 100 ppm of hydroquinone and 5,000 of 6% copper naphthenate into the resultant mixture, and mixing 55% methyl ethyl ketone peroxide with the resultant unsaturated polyester resin.
A concrete non-cure material comprises an embedding agent which is removed by water washing:
- wherein said embedding agent comprises a mixture of sodium silicate, a curing agent with reinforcing agent incorporated therein and a powdered polymer having a high water absorption which is made form mixing propylene glycol with maleic anhydride and either phthalic anhydride or isophthalic acid, dissolving the resultant unsaturated alkyd into 2-hydroxyethyl methacrylate in a weight ratio of 60 to 40 or 70 to 30, adding 100 ppm of hydroquinone and 5,000 ppm of 6% copper naphthenate into the resultant mixture, mixing 55% methyl ethyl ketone peroxide with the resultant unsaturated polyester resin, and hardening the resultant liquid.
