preparation example Construction

[0038] The preparation method of the hot melt adhesive composition of the present invention will be described in detail below.

[0039] figure 2 It is a process flow diagram schematically showing a method for preparing a hot melt adhesive composition described in an embodiment of the present invention.

[0040] refer to figure 2 , The method for preparing a hot melt adhesive composition of the present invention includes the following steps: (S100) preparing and mixing raw materials; and (S200) vacuum degassing the mixed raw materials.

[0041] Prepare and mix ingredients

[0042] The step of preparing and mixing raw materials (S100) is carried out, the purpose of which is to prepare and mix the resin components required for preparing the hot melt adhesive composition.

[0043] The raw materials include butyl rubber, ethylene propylene diene monomer (EPDM) rubber, styrenic block copolymers, amorphous polyalphaolefin (APAO) and tackifying resins, wherein the styrenic bloc...

Embodiment 1

[0089] As shown in the following table 1, the following raw materials are mixed in a mixer: the total weight of the hot melt adhesive composition is 100wt%, 14.5wt% butyl rubber; 14.5wt% ethylene propylene diene (EPDM) rubber; 9.6 wt% of styrene block copolymer containing styrene-isoprene-styrene (SIS) rubber; 7.7 wt% of amorphous polyalphaolefin (APAO); 19.4 wt% of aliphatic petroleum resin as Tackifying resin; 9.6wt% rosin ester as tackifying resin; 9.6wt% terpene resin as tackifying resin; 9.6wt% plasticizer containing polyisobutylene; 4wt% maleic anhydride polypropylene; 1wt% phenolic antioxidant; and 0.5wt% UV stabilizer. Then, the mixed raw materials were vacuum degassed for 4 hours under the conditions of a vacuum degree of 80 mmHg and a temperature of 170° C. using a vacuum pump, thereby obtaining the hot melt adhesive composition of the present invention.

[0090] Then 1.5 g of hot melt adhesive formed from the hot melt adhesive composition was applied to polypropyle...

Embodiment 2 to Embodiment 4

[0092] The hot melt adhesive composition of the present invention was prepared in the same manner as described in Example 1, except that the composition was prepared according to the components, contents and vacuum conditions shown in Table 1 below. Swellable samples were prepared using the prepared compositions.

Abstract

Disclosed is a method for preparing a hot-melt adhesive composition and a hot-melt adhesive composition prepared thereby. The method comprises: preparing and mixing raw materials, including a butyl rubber, an ethylene propylene diene (EPDM) rubber, a styrene block copolymer, an amorphous poly-alpha-olefin (APAO) and a tackifier resin; and performing vacuum degassing of the mixed raw materials, wherein the styrene block copolymer comprises a styrene-isoprene-styrene (SIS) rubber. The hot-melt adhesive composition has high resistance in temperature cycles between low and high temperatures so as to maintain its physical properties, and thus has an excellent property of sealing a headlamp for a long period of time until the end of the lifespan of the headlamp. Also, the composition generates no gas in the sealed state of the headlamp, and thus does not create bubbles or voids and does not pose a water tightness problem.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of Korean Patent Application No. 10-2015-0087222 filed with the Korean Intellectual Property Office on June 19, 2015, the entire disclosure of which is incorporated herein by reference. Background technique [0003] Exemplary embodiments of the present invention relate to a method of preparing a hot melt adhesive composition and a hot melt adhesive composition prepared thereby. More specifically, exemplary embodiments of the present invention relate to a method for preparing a hot melt adhesive composition, wherein air bubbles and gases can be completely removed by vacuum degassing during the preparation of the hot melt adhesive composition, thereby maximizing It maintains the watertightness of a vehicle lamp sealed with the composition and relates to a hot melt adhesive composition prepared by the method. [0004] The rapid development of modern society has made automobiles popular. ...
