Embodiment approach 1

[0029] (1) Weigh 45.032g (0.45mol) of succinic anhydride and 47.313g (0.45mol) of diethanolamine, first add diethanolamine into a three-necked flask with a magnetic stirrer, then dissolve succinic anhydride with an appropriate amount of DMAc; then Put it into the dropping funnel installed on the three-necked bottle of diethanolamine, stir while adding dropwise, after the dropwise addition, raise the temperature to 40°C and react for 12h, and the product of the reaction is AB 2 type monomer. Add 160 mL of toluene (toluene is a water-carrying agent) to the above system first, then add 20.126 g (0.15 mol) of trimethylolpropane as a nuclear molecule, and add 0.500 g of p-toluenesulfonic acid as a catalyst; then start heating until boiling , there is reflux in the spherical condenser tube, and the temperature is raised to 140° C. for 8 hours to obtain a hyperbranched polymer solution with a hydroxyl group at the end. Then weigh 64.854 g (0.90 mol) of acrylic acid and 0.889 g of p-...

Abstract

The invention relates to the field of artificial boards, in particular to a preparation method of hyperbranched paraffin and application of the hyperbranched paraffin in artificial boards. The preparation method includes: synthesizing hydroxyl terminated hyperbranched polymer; using acrylic acid modification to introduce double bonds to the terminal of the polymer to synthesize double-bond hyperbranched polymer; polymerizing the double-bond-terminated hyperbranched polymer with paraffin under the effect of an initiator to obtain the hyperbranched paraffin. The hyperbranched paraffin which is an artificial-board waterproof agent excellent in performance is good in waterproof effect, good in stability and lasting in effect. The synthesizing process of the hyperbranched paraffin is simple andeasy to achieve industrialization.

Description

technical field [0001] The invention relates to the technical field of wood-based panels, in particular to a hyperbranched paraffin wax for improving the water resistance of wood-based panels, and to a preparation method thereof. Background technique [0002] With the development of the home decoration market and the improvement of people's living standards, floor decoration materials are developing in diversification. Wood-based panels are used to manufacture billboards, floors, tables and chairs, signs, toilet decoration, shipping boxes, building templates, vehicle interior decoration, shop facade decoration, etc. due to their beautiful, wear-resistant, practical, and easy-to-clean features. Therefore, the requirements for various physical and mechanical properties of wood-based panels, especially waterproof performance, are getting higher and higher. As we all know, the wood-based panels made of plant fibers still have the characteristics of porosity between the joint po...
