Problems solved by technology

The reason for this is considered to be that the reactivity of the radical polymerizable resin contained in the above-mentioned radical polymerizable resin composition is low, and it is presumed that the unreacted radical polymerizable resin segregates on the surface of the coating film, resulting in a decrease in the surface dryness of the coating film.

Embodiment

[0068] Hereinafter, the present invention will be described in more detail using examples.

Synthetic example 1

[0069] [Synthesis Example 1] Synthesis of Urethane Methacrylate (A-1)

[0070] Into a four-neck flask equipped with a thermometer, a stirrer, an inert gas inlet, an air inlet, and a reflux cooler, polyester polyol ("Polylight OD-X-2044 manufactured by DIC Corporation", number average molecular weight: 2,000) was charged. 1,000 parts by mass and 174 parts by mass of toluene diisocyanate were reacted at 80° C. for 4 hours under a nitrogen stream. After confirming that the isocyanate group equivalent was 1,100 and almost reached the theoretical value, it was cooled to 50°C. Next, 0.07 parts by mass of hydroquinone and 131 parts by mass of 2-hydroxyethyl methacrylate were added under air flow, and reacted at 90° C. for 5 hours. When the isocyanate % became 0.1% or less, 0.07 mass parts of t-butyl catechols were added, and number average molecular weight: The urethane methacrylate (A-1) of 2,608 was obtained.

Synthetic example 2

[0071] [Synthesis Example 2] Synthesis of Urethane Methacrylate (A2)

[0072] Into a four-necked flask equipped with a thermometer, a stirrer, an inert gas inlet, an air inlet, and a reflux cooler, polycarbonate polyol ("ETERNACOLL UH-200" manufactured by Ube Industries, Ltd., number average molecular weight 2,000) was charged. 1,000 parts by mass and 174 parts by mass of toluene diisocyanate were reacted at 80° C. for 4 hours under a nitrogen stream. After confirming that the isocyanate group equivalent was 1,100 and almost reached the theoretical value, it was cooled to 50°C. Next, 0.07 parts by mass of hydroquinone and 131 parts by mass of 2-hydroxyethyl methacrylate were added under airflow, and reacted at 90° C. for 5 hours.

Abstract

The aim of the invention is to provide a free radical polymerized resin composite which can provide a coating film being dry in surface and excellent in tensile property. The free radical polymerized resin composite is characterized in that the composite comprises a urethane (meth) acrylate (A), a free radical polymerized monomer (B) and an acrylic polymer (C). In addition, the invention provides a civil construction material, and the civil construction material is characterized by comprising the above free radical polymerized resin composite. By employing the free radical polymerized resin composite, a coating film which is dry in surface and excellent in tensile property can be obtained, and the free radical polymerized resin composite is suitable for the manufacture of civil construction materials such as floor materials, paving materials, waterproof materials, road coatings, priming paint, wall surface coating materials, road marking materials, injecting materials, adhesives, lining materials, wave absorbing plates and the like in factories, warehouses, cleaning rooms and the like.

Description

technical field [0001] The present invention relates to a radically polymerizable resin composition capable of obtaining a coating film excellent in surface dryness and tensile properties. Background technique [0002] In civil engineering and construction fields such as road paving, unsaturated polyesters, polyester (meth)acrylates, epoxy (meth)acrylates, and urethane (meth)acrylates are widely used in response to shortened construction periods. Radical polymerizable resins such as esters, and radical polymerizable resin compositions containing radical polymerizable monomers (for example, refer to Patent Document 1). [0003] Although the above-mentioned radically polymerizable resin composition has excellent tensile strength and is suitable for spraying, it needs further improvement in the surface dryness of the coating film. This is considered to be due to the low reactivity of the radically polymerizable resin contained in the radically polymerizable resin composition, ...
