preparation example Construction

[0031] One, the preparation method of acrylate polymer:

[0032] Under the conditions of stirring and nitrogen protection, 0.1-3% (to monomer content) of thermal initiator benzoyl peroxide and various acrylate mixtures are heated in toluene solution (30-70% in different concentrations) In the polymerization reaction, the polymerization temperature is 65-110° C., and the polymerization time is 3-10 hours.

[0033] The molecular weight of the polymer is controlled by the polymerization time, polymerization temperature, initiator dosage and toluene content.

[0034] The properties of the polymer are controlled by the type of acrylate used during polymerization.

[0035] The acrylate may be ethyl acrylate, butyl acrylate, octyl acrylate, acrylic acid, lauryl acrylate, octadecyl acrylate, hydroxyethyl acrylate, hydroxypropyl acrylate, propyl acrylate, methyl acrylate and the like.

Synthetic example 1

[0037] Ethyl acrylate (25%), butyl acrylate (20%), octadecyl acrylate (10%), hydroxyethyl acrylate (20%), a total of 100 grams of methyl acrylate (25%) were added to 100 grams of toluene , add 0.1 g of benzoyl peroxide, heat up to 80°C, react for 10 hours and wait for the product to be used for further reaction.

Synthetic example 2

[0039] Octyl acrylate (30%), butyl acrylate (20%), lauryl acrylate (15%), hydroxypropyl acrylate (20%), and 100 grams of propyl acrylate (15%) were added to 50 grams of toluene , add 0.5 g of benzoyl peroxide, heat up to 65° C., react for 6 hours and wait for the product to be used for further reaction.

Abstract

The invention relates to a kind of acrylate polymer, the synthesizing method and its application, belonging to environment- friendly light solid coating and application field. The method comprises following steps: mixing heat initiator benzoyl peroxide and acrylate, feeding said mixture into toluene under stirring and nitrogen gas protection condition for heat plolymerization, getting acrylate ploymer, adding acrylic acid into acrylate ploymer, adding p-toluenesulfonic acid as catalyst and eldopaque as inhibitor, reaction at 100- 120 Deg. C, removing water, decompressing to remove disslovant and unreacted material, and getting final product. The product can be used as additive for wood paper surface working, and it can imcrease sealing performance for wood micropore and adhesive force to wood paper.

Description

technical field [0001] The invention belongs to the field of environment-friendly photocuring paint and its application, in particular to the formulation of free radical photocuring system and the synthesis of special additives. Background technique [0002] Photoradical polymerization is the use of light as the reaction force, through the action of light on light-sensitive compounds, so that a series of photophysical and photochemical reactions occur, and active material free radicals are generated. Under the initiation of free radicals, the polymerizable monomers Polymerization occurs, and finally the liquid resin is converted into a solid polymer material. Its aggregation characteristics are: [0003] (1) Energy saving: energy consumption in the photopolymerization process only needs to ensure that the active chemical formula undergoes polymerization and crosslinking reaction under light irradiation, and there is no need to heat the substrate, so the energy consumption o...
