Example Embodiment

[0036] Example 1

[0037] Preparation of Epoxy Latex in Wuyi: 100 parts by weight of Wuyi oxide epoxy monomer, 200 parts of deionized water, 5 parts of emulsifier, 5 serviced, 0.5 parts of pH adjusting agent by stirring, ultrasound alternate about 1 h The premix is ​​mixed, and the premixture is substantially 20% by weight of the premixture in the three flasks, heated to 60 ° C, adding 0.3 parts by weight of the initiator reaction for 30 minutes, starting to add the remaining premix, dripping speed about 3 seconds / drop. After the prematurated droplets were added, 0.3 parts of the initiator continued to react for 4 hours, warmed to 80 ° C for 30 minutes, and finally cool down to the room temperature over the nylon filters to give the ubiquite oil epoxy latex.

[0038] like figure 1 As shown in, the plant oil-based fatty acid cyclic oxygen monomer: the preparation process of the ubiquite oil epoxy monomer is as follows:

[0051] Example 2

[0052] Preparation of palm oil epoxy latex: 200 parts by weight of Palm oxide monomer, 400 parts of deionized water, 10 parts emulsifier, 10 parts of milk, 1 part pH adjusting agent, ultrasonic mix, uniformly forming premixture . Take about 20% by weight of the prematurate in three flasks, heated to 60 ° C, adding 0.6 parts by weight of the initiator reaction for 30 minutes, starting to add the remaining premix, and the dropping speed is about 5 seconds per drop. After the prematurated droplets were added, 0.6 parts by weight initiator continued to react for 5 hours, warmed to 80 ° C for 30 minutes, and finally cooling to the room temperature over the nylon filters, i.e., Palm oil epoxy latex.

[0053] Among them, the vegetable oil-based fatty acid cyclic oxygen monomer: the preparation process of the palm oil epoxy monomer is in Example 1.

[0054] The preparation method of vegetable oil-based adhesive is in Examples 1.

[0055] Example 3

[0056] Preparation of high oleanic vegetable seed oil epoxy latex: 150 parts of high oleic vegetable seed oil epoxy monomer, 300 denominates, 7.5 parts of emulsifier, 7.5 parts of the milk, 0.75 parts of pH adjusting agent Stir, ultrasonic mixing is uniformly formed. Take about 20% by weight of prematurate in three flasks, heated to 60 ° C, adding 0.45 parts by weight of the initiator to react for 30 minutes, and start to add the remaining premix, and the dropping speed is about 4 seconds per drip. After the prematurated droplets were completed, 0.45 parts of the initiator continued to react for 3 hours, warmed to 80 ° C for 30 minutes, and finally cooled to the room temperature over the nylon filters to give high oleanic vegetable seed oil epoxy latex.

[0057] Among them, the vegetable oil-based fatty acid cyclic oxygen monomer: the preparation process of high oleanic vegetable seed oil epoxy monomers is the same.

Abstract

The invention provides vegetable oil-based latex, which is synthesized by taking vegetable oil as a raw material, and is a bio-based material, wherein the epoxidized vegetable oil monomer has a conversion rate of more than 98%, so that the requirement of emulsion polymerization is met. According to the invention, the vegetable fat-based latex prepared through emulsion polymerization can be directly coated on a base material to be dried in the air to complete adhesion to be used as a pressure-sensitive adhesive, and can also be dried in the air to be heated and cured to be used as a thermosetting adhesive, and tests show that the latex has good adhesion; and the vegetable fat-based latex can be used as bio-based epoxy resin after being cured at high temperature by adding a curing agent, and the cured epoxy resin has excellent mechanical properties.

Description

technical field [0001] The invention relates to the technical field of bio-based latex, in particular to a vegetable oil-based latex, a preparation method and an application thereof. Background technique [0002] The main component of vegetable oil is fatty acid triglyceride, and fatty acid accounts for about 95% of the total weight of triglyceride. Due to the variety and origin of oil crops, the length and degree of unsaturation of fatty acid chains are also different. Common fatty acids include palmitic acid, stearic acid, oleic acid, linoleic acid, linolenic acid, etc. For example, the fatty acids in palm oil are mainly palmitic acid, oleic acid and linoleic acid, rapeseed oil, soybean oil and high oleic acid Sunflower oil is mainly composed of oleic acid and linoleic acid, and tallow tree oil is mainly composed of linoleic acid, linolenic acid and oleic acid. In addition to these common components, there are also some special components, such as tungoleic acid in tung o...
