一种双组分室温固化胶粘剂及其制备方法
摘要：
本发明提供了一种双组分室温固化胶粘剂及其制备方法，该双组分室温固化胶粘剂包括A组分和B组分；所述A组分由包括如下重量份的原料制得：40～50份酚醛乙烯基酯树脂和30～40份双酚A型环氧乙烯基树脂；所述B组分包括过氧化物引发剂；所述A组分和B组分的重量比满足以下条件：所述A组分和B组分混合后以使所述过氧化物引发剂占A组分和B组分混合后总重量的0.5～3.5％。本发明选用酚醛乙烯基酯树脂和双酚A型环氧乙烯基树脂为A组分的主体树脂，选取过氧化物引发剂为B组分的有效成分，极大加快了胶粘剂的室温固化速度，能使胶粘剂在电子产品的粘结使用中表现出更优异的稳定性。
摘要（英）：

The invention provides a double-component room-temperature curing adhesive and a preparation method thereof. The double-component room-temperature curing adhesive is prepared from a component A and acomponent B, wherein the component A is prepared from the following raw materials in parts by weight: 40 to 50 parts of novolac vinyl ester resin and 30 to 40 parts of bisphenol A type epoxy vinyl resin; the component B comprises a peroxide initiator; the weight ratio of the component A to the component B meets the following conditions: after the component A and the component B are mixed, the peroxide initiator accounts for 0.5 to 3.5 percent of the total weight of the mixture of component A and component B. According to the double-component room-temperature curing adhesive, the novolac vinylester resin and the bisphenol A type epoxy vinyl resin are selected as main body resin of the component A, and the peroxide initiator is selected as an effective component of the component B, so thatthe room-temperature curing speed of the adhesive is extremely increased and the adhesive shows more excellent stability when being used for bonding electronic products.
