Embodiment 1

[0027] Temperature-resistant / environmentally friendly high-viscosity and high-strength SEBS adhesive, which includes the following components: SEBS rubber, tackifying resin (including C 5 Petroleum resin, terpene resin, rosin and 138 resin mixture), antioxidant 300, 6# solvent gasoline, ester solvent (methyl acetate, ethyl acetate) solvent.

[0028] Among them, the weight percentages of SEBS rubber, tackifying resin, antioxidant 300, 6# solvent gasoline and ester solvents are: 15%, 28%, 0.5%, 48.5%, and 8%.

[0029] C in tackifying resin 5 The weight ratio of petroleum resin, terpene resin, rosin and 138 resin is 1:2:3:10 in sequence.

[0030] The weight ratio of methyl acetate and ethyl acetate in the ester solvent is 2:3 in turn.

[0031] The preparation method of the above-mentioned temperature-resistant / environmental protection type high-viscosity high-strength SEBS glue comprises the following steps in turn:

[0032] a. First put quantitative 6# solvent gasoline and es...

Embodiment 2

[0043] Temperature-resistant / environmentally friendly high-viscosity and high-strength SEBS glue, which includes the following components: SEBS rubber: 11%, rosin: 4%, rosin pentaerythritol ester: 5%, terpene resin: 2.8%, C 9 Petroleum resin: 12%, antioxidant 330: 0.2%, methyl acetate: 6%, butyl acetate: 10%, 6# solvent gasoline: 49%.

[0044] Antioxidant 330, scientific name 1,3,5-trimethyl-2,4,6-tris(3,5-tert-butyl-4-hydroxybenzyl)benzene. It is a high molecular weight polybasic hindered phenol. It has the characteristics of no pollution, no discoloration, low toxicity, and high antioxidant capacity.

[0045] Structural formula:

[0046]

[0047] Molecular formula: C 54 h 78 o 3

[0048] When preparing the above-mentioned temperature-resistant / environment-friendly high-viscosity and high-strength SEBS glue, first put quantitative 6# solvent gasoline and ester solvents (methyl acetate, butyl acetate) into the mixer, start the machine to stir evenly; then put the SEBS...

Embodiment 3

[0052] Temperature-resistant / environment-friendly high-viscosity and high-strength SEBS glue, which includes the following components: SEBS rubber: 14%, C 5 Petroleum resin: 4.5%, 138 resin: 4.5%, rosin pentaerythritol ester: 2.8%, terpene resin: 10%, antioxidant 300: 0.2%, butyl acetate: 8%, ethyl methyl carbonate: 8%, 6 #Solvent gasoline: 48%.

[0053] The preparation method is the same as in Example 1. This method is used to prepare high-viscosity and high-strength SEBS glue.

[0054] The product obtained by this method can replace solvent-based neoprene, and can reach the viscosity of neoprene, but its solid content is higher than that of neoprene, low in VOC content, and less harmful to human body. It is an environmentally friendly adhesive.

Abstract

The invention belongs to the field of adhesive and particularly relates to a heat resistance / environmental protection type high viscosity and high strength SEBS adhesive and a preparation method thereof. The SEBS adhesive comprises the following components by weight percent: 9-15% of SEBS rubber, 18-35% of tackifying resin, 0.2-1.5% of antioxidant, 40-60% of gasoline solvent and 8-20% of ester solvent. The preparation method comprises the following steps: 1) pouring a define amount of gasoline solvent and ester solvent in a mixer, starting the mixer to mix evenly; 2) adding SEBS rubber in a reactor; 3) adding tackifying resin and antioxidant in the mixer to mix; and 4) adding all the materials obtained in the step 1), the step 2) and the step 3) in the mixer to mix for about 1-4 hours to ensure that the materials are dissolved to obtain light yellow and uniform adhesive, and filtering with a screen. The SEBS adhesive is non-toxic and has high bonding strength and ideal ageing resistant / heat resistant index.

Description

technical field [0001] The invention belongs to the field of adhesives, and in particular relates to a temperature-resistant / environmental protection type high-viscosity and high-strength SEBS adhesive and a preparation method. Background technique [0002] SEBS is a hydrogenated product of thermoplastic elastomer SBS, often called hydrogenated SBS. SEBS is a linear three-block copolymer with polystyrene as the terminal block and ethylene-butene copolymer obtained by hydrogenation of polybutadiene as the middle elastic block. SEBS does not contain unsaturated double bonds, so it has good stability and aging resistance. [0003] SBS is an excellent styrene-based plastic elastomer. It has physical properties similar to vulcanized rubber without being vulcanized. It can be directly injection molded and can be recycled 100%. It has been widely used in various fields. However, the SBS main chain contains a large number of aliphatic double bonds, which is not resistant to climat...
