Embodiment approach

[0061] As a preferred embodiment of the present invention, in the HO-SBS, the grafting ratio of hydroxyl groups is 25-40%.

[0062] As a preferred embodiment of the present invention, in the HO-SBS, the grafting rate of hydroxyl groups is 33%.

[0063] The white mineral oil used in this application is not particularly limited, and may be a commercially available product.

[0064] The term "antioxidant" in the present invention refers to a compound that can prevent or inhibit the oxidation process by causing macromolecular chain breakage, crosslinking, and performance deterioration due to the oxidation of polymers. Antioxidants are divided into two categories: free radical terminators and hydroperoxide decomposing agents. The free radical terminator mainly generates inactive free radicals or stable products through chain transfer to terminate the chain. Sterically hindered phenols, aromatic amines and certain cyclic hydrocarbons are good free radical stabilizers. Phenolic com...

Embodiment 11）

[0133] Example 11) First put 50 parts by weight of D1, 20 parts by weight of E1 and 0.5 parts by weight of F1 into stainless steel

[0134] In the reactor, after heating up to 120°C, add 100 parts by weight of A1 and 10 parts by weight of B1, and control the temperature of the reactor within 140°C;

[0135] 2) Add 150 parts by weight of C1 and 5 parts by weight of G1 after all the SBS and HO-SBS are dissolved,

[0136] Control the temperature of the stainless steel reactor at 140°C and stir for 30 minutes;

[0137] 3) Vacuumize the inside of the reactor to -0.085Mpa, discharge the material, and pack it after cooling.

Abstract

The invention discloses environment-friendly anti-aging automobile inner decorating glue. The glue is prepared from SBS, hydroxy-terminated hyperbranched polyurethane, HO-SBS, white mineral oil, dimethyl sulfoxide, antioxidant and silane modified hyperbranched polyimide, wherein the silane modified hyperbranched polyimide is prepared from raw materials including epoxy silane coupling agent and amino-terminated hyperbranched polyimide. The invention further discloses a preparation method of the environment-friendly anti-aging automobile inner decorating glue.

Description

technical field [0001] The invention belongs to the field of glue for bonding, and more specifically, the invention relates to an environment-friendly anti-aging automotive interior glue and a preparation method thereof. Background technique [0002] With the development of the automobile industry, the interior of the car is becoming more and more luxurious, so the amount of glue used for bonding the interior of the car is also increasing. At present, the adhesives used in automotive interiors usually contain a large amount of harmful substances such as formaldehyde, benzene, and xylene due to the use of non-environmentally friendly organic solvents, which pose a huge threat to human health. In addition, the automotive interior adhesives in the prior art also have the disadvantages of weak initial adhesion and poor anti-aging performance, which need to be solved urgently. [0003] Therefore, it is very necessary to prepare an environment-friendly high-adhesive, high-aging...
