preparation example Construction

[0038] A kind of preparation method of the solvent glue that is used for SEBS base plastic runway bonding, comprises the following steps:

[0039] Step 1: Weigh 10-30 parts of thermoplastic elastomer TPE, 10-40 parts of tackifying resin, 20-30 parts of mineral spirits, and 10-20 parts of ester solvent in parts by weight, and pour them into the reaction kettle in turn as the bottom Material, control the reaction temperature at 78°C-82°C by reflux to completely dissolve it.

[0040] Step 2: React 100 parts of hydroxyl-terminated polybutadiene, 10-30 parts of isocyanate molecules, and 0.1-1.0 parts of organotin catalyst under nitrogen protection at 60°C for 6 hours to control the relationship between hydroxyl-terminated polybutadiene and isocyanate molecules. The molar ratio is 1:2-1:3 to obtain isocyanate-terminated polybutadiene.

[0041] Step 3: Weigh 20-60 parts of isocyanate-terminated polybutadiene, add it into the mixed system dissolved in Step 1, stir evenly under nitrog...

Abstract

The invention discloses a solvent adhesive for SEBS-based plastic runway bonding and a preparation method thereof. The solvent adhesive is mainly prepared from the following raw materials in parts byweight: 10-30 parts of thermoplastic elastomer TPE, 10-40 parts of tackifying resin, 20-30 parts of solvent oil, 10-20 parts of an ester solvent and 20-60 parts of isocyanate-terminated polybutadiene.The isocyanate-terminated polybutadiene is obtained by reacting 100 parts of hydroxyl-terminated polybutadiene, 10-30 parts of isocyanate molecules and 0.1-1.0 part of an organic tin catalyst. The solvent adhesive realizes rapid initial adhesion with a runway by virtue of the thermoplastic elastomer TPE and the tackifying resin after solvent volatilization within 10 minutes, and the bonding strength is improved by virtue of isocyanate water vapor curing in the later period. The solvent adhesive developed by the invention has the characteristics of fast initial adhesion, strong adhesion, stable properties after curing and the like.

Description

technical field [0001] The invention relates to the field of chemical process solvent glue, in particular to a solvent glue used for bonding SEBS-based plastic runways and a preparation method thereof. Background technique [0002] With the country's vigorous advocacy of national sports, the demand for sports venues, especially plastic tracks, has increased year by year, and higher requirements have been put forward for the durability and construction methods of plastic tracks. The prefabricated SEBS-based plastic runway, as a new type of fully recyclable and environmentally friendly plastic runway, can replace the traditional on-site paved runway and has better stability. It has been popularized and applied in various sports venues. However, how to achieve stable side bonding between prefabricated plastic runways is a problem that the industry needs to solve urgently. [0003] At present, there is no mature solution for the side bonding between prefabricated plastic runway...
