Embodiment 1

[0069] The coating composition was prepared by mixing 50% by weight of OMYA-N (OMYA DEV AG) as a pigment, 15% by weight of SE-57 (NOROO CHEMICAL CO.) as a water-soluble starch binder, and 0.5% by weight as a dispersant NOPCO-44 (SAN NOPCO KOREA LTD.), 0.2% by weight of NOPCO-8034 (SAN NOPCO KOREA LTD.) as a defoamer, 0.2% by weight of BYK-346 (BYK CHEMICAL CO.) as a wetting agent, 0.7% by weight of ER-4400 (DOW CHEMICAL CO.) as a thixotropic agent, 0.3% by weight of ammonia water (Toko Chemical Co., Ltd.) as a pH adjuster, 0.1% by weight of XIAMETER OFS-6040 as a silane derivative (Dow Corning Corporation), and 33% by weight of water. The glass transition temperature of the coating composition is 13°C.

Abstract

A paint composition for a vinyl greenhouse is provided to control the inner temperature of the green house to a moderate level by blocking the input of heat energy inside the greenhouse when painted on the outer side of a greenhouse finishing material. A paint composition for a vinyl greenhouse includes 30-70 wt% of a pigment; 3-25 wt% of a water-soluble binder manufactured by emulsifying starch; 0.1-0.7 wt% of a dispersant; 0.01-0.3 wt% of a foaming agent; 0.01-0.3 wt% of a moisturizing agent; 0.1-1 wt% of a viscoelasticity controller; 0.1-2 wt% of a pH controller; 0.01-1 wt% o a silane derivative; and residual water. A forming method of a coating includes a step of manufacturing the paint composition; a step of spreading the paint composition on an elastic substrate including a polyethylene film and a polyvinyl film; and a step of drying the spread material.

Description

[0001] Related Application Cross Reference [0002] This application claims priority to Korean Patent Application No. 2012-0019874 filed on Feb. 27, 2012 at the Korean Intellectual Property Office (KIPO), the entire contents of which are incorporated herein by reference. technical field [0003] Exemplary embodiments of the present invention relate to a coating composition for a greenhouse and a method of manufacturing a coating film using the coating composition. In particular, exemplary embodiments of the present invention relate to a method of effectively shielding the heat of the sun to provide a suitable temperature inside a vinyl plastic greenhouse, and a method of manufacturing a coating film using the coating composition. Background technique [0004] In addition to suitable humidity and temperature, sufficient light is usually required for the healthy growth and development of plants, so that plants can fully perform photosynthesis and absorb carbon dioxide, because...
