Embodiment 1

[0042] Polyether polyol Voranol TM 2000LM 500g was heated and dehydrated in a three-necked flask connected with a vacuum device and equipped with a stirrer and a thermometer for 2h, and then slowly added 125g of aromatic diisocyanate MDI-50 to react for 2-3h to prepare a prepolymer with an NCO% of 3.36%. That is, component A of the damping layer. Component B consists of 11 parts of chain extender tripropylene glycol (TPG), 32.9 parts of liquid flame retardant tris(2-chloropropyl) phosphate (TCPP), 55.7 parts of 100 mesh mica powder, and defoamer BYK-A530 0.2 parts, catalyst bismuth isooctanoate Bicat Zn 0.2 parts are mixed and stirred in a kneader. A and B components are mixed at a mass ratio of 3:2 (functional group equivalent ratio 1.05:1), stirred, and then scraped on the surface of the metal substrate with an anti-corrosion primer. The thickness of the scraped coating is about 1mm. A damping layer is obtained after curing.

Embodiment 2

[0050] Polyether polyol Voranol TM 1000LM 500g was heated and dehydrated in a three-neck flask connected with a vacuum device and equipped with a stirrer and a thermometer for 2h, then slowly added 250g of aromatic diisocyanate MDI-50 to react for 2-3h to prepare a prepolymer with an NCO% of 5.6%. That is, component A of the damping layer. Component B consists of 13.95 parts of chain extender 2-ethyl-1.3-hexanediol (EHD), 35 parts of liquid flame retardant tris(2-chloropropyl) phosphate (TCPP), 50.55 parts of 400 mesh mica powder, 0.25 parts of defoamer BYK-A530 and 0.25 parts of catalyst Bicat Zn are mixed and stirred in a kneader. A and B components are mixed at a mass ratio of 3:2 (functional group equivalent ratio 1.05:1), stirred, and scraped on the surface of the metal substrate with an anti-corrosion primer. The thickness of the scraped coating is about 1mm. A damping layer is obtained after curing.

Embodiment 3

[0059] Polyether polyol Voranol TM 1000LM 500g was heated and dehydrated in a three-necked flask connected with a vacuum device and equipped with a stirrer and a thermometer for 2 hours, then slowly added 174g of aromatic diisocyanate TDI-80 / 20 to react for 2-3 hours to prepare a prepolymer with an NCO% of 6.2%. The body is the A component of the damping layer. Component B consists of 18.2 parts of chain extender DPG, 35 parts of liquid flame retardant tris(2-chloropropyl) phosphate (TCPP), 46 parts of 400 mesh mica powder, 0.4 parts of defoamer BYK-A530, catalyst isooctanoic acid Bicat Zn 0.4 parts are mixed and stirred in a kneader. A and B components are mixed at a mass ratio of 2:1 (functional group equivalent ratio 1.05:1), stirred, and then scraped on the surface of the metal substrate with an anti-corrosion primer. The thickness of the scraped coating is about 1mm. A damping layer is obtained after curing.

Abstract

The invention discloses a polyurethane damping floor material and a preparation method thereof. The material includes a two-layer structure of a damping layer and a constraining layer. Among them, the damping layer material is a two-component solvent-free polyurethane material, including A component and B component. A component is a polyurethane prepolymer with an isocyanate content of 3%~6%, and B component is a curing agent. The ingredients are chain extender, liquid flame retardant, functional filler, catalyst, defoamer, etc. Constraining layer material is polyaspartic acid ester type polyurethane material, including A component and B component, A component is HDI trimer, isocyanate content is 15%~20%, B component is curing agent , the main components are polyaspartate chain extender, liquid flame retardant, solid flame retardant, molecular sieve, defoamer, etc. The material can be widely used in vibration and noise reduction of home decoration, floors, workshops and other grounds. The material has good damping performance, flame retardant performance, wear resistance and construction process performance.

Description

technical field [0001] The invention specifically relates to a polyurethane damping floor material and a preparation method thereof, belonging to the field of building materials. Background technique [0002] The floor refers to the use of specific materials and techniques to carry out construction treatment on the original ground and present a certain decorative and functional ground. Polyurethane floor refers to the use of polyurethane floor coating combined with a new type of solvent-free, non-polluting ground decoration construction technology to meet certain specific use requirements (high-end conference or entertainment centers focus on comfort requirements; industrial and mining enterprises focus on anti-corrosion and durability) grinding requirements, etc.), it is especially suitable for various industrial and mining enterprise workshops, parking lots, sports fields and other floor coatings that require anti-slip, anti-corrosion, and wear-resistant. Polyurethane flo...
