Embodiment 1

[0017] This embodiment provides an adhesive for yachts, which is used in the adhesion of yachts made of PVC. It has the characteristics of strong initial adhesion and excellent weather resistance. The adhesive is 70-85% by weight Organic solvent and 15-30% main agent are raw materials, the two raw materials are mixed and stirred at 30-40°C for 1-2 hours to obtain a solid content of 15-30% and a rotational viscosity of 300 at 25°C ~600mPa·s adhesive; wherein, the main agent is 92~93% polyester polyol and 7~8% toluene diisocyanate by weight percentage as raw materials, each raw material is heated at 75~95 ℃ After mixing and reacting at high temperature for 1-2 hours, the resin obtained is extruded and granulated by twin-screw. Organic solvent can adopt any one in toluene, ethyl acetate, methyl acetate, butanone or acetone.

[0018] The polyester polyol in the above-mentioned main ingredient is a polyester with a hydroxyl value of 45-55 mgKOH / g, an acid ester of 0.1-2 mgKOH / g, a...

Embodiment 2

[0042] This embodiment provides an adhesive for yachts, which is used for bonding yachts made of PVC, and has the characteristics of strong initial adhesion and excellent weather resistance. The preparation method of the adhesive is as follows:

[0043] Prepare the main ingredient:

[0044] (a) prepare main ingredient polyester polyol, get each raw material according to following formula:

[0045]

[0046] Steps:

[0047] (1) primary esterification:

[0048]Add 27 parts by mass of 1,4 succinic acid and 35 parts by mass of hexanediol into the polyester synthesis kettle, raise the temperature of the polyester synthesis kettle to 210-230°C, and react for 2-3 hours; during the reaction, keep The water output of the polyester synthesis kettle is stable (the water output is 0.5-1.0% / hour of the total weight of raw materials input into the primary esterification), and the distilled water is 8.24%;

[0049] (2) Secondary esterification:

[0050] Add 20 parts by mass of isophtha...

Embodiment 3

[0063] This embodiment provides an adhesive for yachts, which is used for bonding yachts made of PVC, and has the characteristics of strong initial adhesion and excellent weather resistance. The preparation method of the adhesive is as follows:

[0064] (a) the preparation of polyester polyol, get each raw material that prepares polyester polyol by following formula:

[0065]

[0066] Steps:

[0067] (1) primary esterification:

[0068] Add 30 parts by mass of 1,4 succinic acid and 35 parts by mass of hexanediol into the polyester synthesis kettle, heat up to 210-230° C., and react for 3 hours. During the reaction, keep the water output stable (the water output is 0.5 to 1.0% of the total weight of the raw material is put into the esterification once per hour), and the distilled water is 9.15%;

[0069] (2) Secondary esterification:

[0070] Add 18 parts by mass of isophthalic acid and 17 parts by mass of ethylene glycol to the polyester synthesis kettle after primary es...

Abstract

The invention discloses an adhesive for the yacht and a preparation method thereof, belonging to the adhesive field. The adhesive comprises the following raw materials by weight percent: 70-85% of organic solvent and 15-30% of main agent. The preparation method is as follows: the two raw materials are mixed and stirred at 30-40 DEG C for 1-2 hours to obtain the adhesive of which solid content is 15-30% and the rotary viscosity is 300-600mPa.s at 25 DEG C, wherein the main agent comprises the following raw materials by weight percent: 92-93% of polyester polyol and 7-8% of toluene diisocynate;and the preparation method of the main agent is that the raw materials are mixed to react at 75-95 DEG C for 1-2 hours and a double screw extruder is used to granulate and prepare resin, namely the main agent. In the adhesive of the invention, soft polyester units are introduced in high-crystallinity two-functionality small molecules such as 1,4-succinic acid; and non-aromatic isocyanic acid is introduced in the synthesis process, thus the polyurethane adhesive has better initial adhesion and more excellent weather resistance compared with the traditional yacht adhesive in the market.

Description

technical field [0001] The invention belongs to the technical field of adhesives, and more specifically relates to an adhesive for yachts and a preparation method thereof. Background technique [0002] Yacht is a high-grade durable consumer goods for water entertainment. It integrates navigation, sports, entertainment, leisure and other functions to meet the needs of individuals and families to enjoy life. In developed countries, yachts are mostly privately owned like cars, while in developing countries, yachts are mostly used as parks and tourist attractions for people to consume, and a small amount are also used as working means for port supervision, public security, and border defense. The essential feature of a yacht as a recreational tool makes it different from high-speed ships and tourist ships as means of transportation. [0003] In the yacht manufacturing process, especially the PVC material series yachts, the use of adhesives is inseparable from the bonding and s...
