Embodiment 1

[0076] After fully dissolving 50g of PVA 1788 with 450g of dimethyl sulfoxide, add 0.5g of organotin catalyst under stirring, add 3g of ethyl acrylate-2-isocyanate and 10g of dimethyl sulfoxide dropwise at 60°C Solution, react for one hour to obtain ethyl acrylate isocyanate modified polyvinyl alcohol resin solution; slowly add the reaction solution to 1000ml ethanol for precipitation, take out the precipitate and dry it in vacuum at 70°C to constant weight to obtain acrylate isocyanate Modified polyvinyl alcohol resin.

Embodiment 2

[0078] After fully dissolving 50g of PVA 1788 with 450g of dimethyl sulfoxide, add 0.5g of organotin catalyst under stirring, dropwise add the solution made of 5g of blocked ethyl acrylate-2-isocyanate and 20g of dimethyl sulfoxide, in React for one hour at 100°C to obtain ethyl acrylate isocyanate modified polyvinyl alcohol resin solution; slowly add the reaction solution to 1000ml of ethanol for precipitation, take out the precipitate and dry it in vacuum at 70°C to constant weight to obtain acrylic acid Isocyanate modified polyvinyl alcohol resin.

Embodiment 3

[0080] After fully dissolving 50g of PVA 1788 with 450g of dimethyl sulfoxide, add 0.5g of organotin catalyst under stirring, add 3.3g of ethyl methacrylate-2-isocyanate and 10g of dimethyl sulfoxide dropwise at 60°C The prepared solution was reacted for one hour to obtain the isocyanate ethyl methacrylate modified polyvinyl alcohol resin solution; the reaction solution was slowly added to 1000ml of ethanol for precipitation, and the precipitate was taken out and dried in vacuum at 70°C to constant weight , to obtain methacrylic acid isocyanate modified polyvinyl alcohol resin.

Abstract

The invention relates to the technical field of materials, in particular to modified resin for a water-based material and a preparation method thereof, the modified resin comprises matrix resin and aside chain group graft on the matrix resin; the matrix resin comprises at least one of polyvinyl alcohol resin and polyvinyl acetate resin with hydroxyl; each of the side chain group grafts comprisesat least one isocyanate group and at least one vinyl group. The modified resin for the water-based material provided by the invention can be used as an active emulsifier of various water-based materials, e.g., water-based ink, water-based paint, water-based photo-sensitive adhesive, water-based adhesive, photoresist, 3D printing materials and the like. The water-based photo-curing resin is especially suitable for water-based photo-curing ink, water-based photo-curing paint, water-based photo-curing photo-sensitive adhesive, water-based photoresist and water-based photo-curing 3D printing materials, and has excellent curing reaction activity, water resistance, acid and alkali resistance, solvent resistance, wear resistance, cohesiveness and strength.

Description

technical field [0001] The invention relates to the field of material technology, in particular to a modified resin for water-based materials and a preparation method thereof. Background technique [0002] Water-based materials, such as water-based inks, water-based coatings, water-based photosensitive adhesives, water-based adhesives, photoresists, 3D printing materials, etc., especially water-based light-curable inks, water-based light-curable coatings, water-based light-curable photosensitive adhesives, water-based light-curable Adhesives, water-based photoresists, water-based photocurable 3D printing materials, etc., while solving the problems of VOC emissions and safety of use of oily materials, they also bring about a serious problem, that is, water resistance and wear resistance. , seriously restricting the application of water-based materials. [0003] Water-based materials, in order to achieve the purpose of water-based, that is, use water as a solvent or dispersio...
