The invention discloses a method for preparing a 6,6'-bi(2,3-dimethoxyphenyl)-alpha,alpha-D-trehalose intermediate. The method comprises the following steps: (1) dissolving 2,3-dimethoxybenzoic acid in anhydrous tetrahydrofuran, adding N,N'-carbonyl diimidazole, stirring at room temperature, and performing carboxyl activation; (2) adding a compound shown as a formula II and N-bromo-succinimide in a catalytic amount into the reaction solution subjected to carboxyl activation in the step (1), stirring and reacting; and (3) adding water into the solution reacted in the step (2), stirring for 10-15 minutes, extracting for three times by using dichloromethane, mixing the organic layers, washing for three times by using a saturated potassium carbonate aqueous solution, washing by using saturated salt, drying by using anhydrous sodium sulfate, filtering, concentrating, recrystallizing the residues by using ethanol / water, thereby obtaining the 6,6'-bi(2,3-dimethoxyphenyl)-alpha,alpha-D-trehalose intermediate, removing the trimethylsilyl of the intermediate under weakly acidic conditions, thereby obtaining 6,6'-bi(2,3-dimethoxyphenyl)-alpha,alpha-D-trehalose. The method disclosed by the invention is mild in reaction conditions, low in cost and suitable for industrial production.

The invention discloses a combined jute blocking paster. The combined jute blocking paster comprises a main body and a jute eyelet fabric covering the main body, wherein the main body comprises an outer blocking ring and an inner blocking ring; the outer blocking ring and the inner blocking ring are connected with each other and concentrically arranged; the outer blocking ring has a first cylindrical body group obliquely and upwardly extending towards the outer side of the outer blocking ring from the upper surface of the outer blocking ring; the inner blocking ring has a second cylindrical body group vertically and upwardly extending from the upper surface of the inner blocking ring; and the first cylindrical body group and the second cylindrical body group penetrate the jute eyelet fabric.
