AI Technical Summary

Problems solved by technology

[0003] At present, there are still some deficiencies in the existing flocking adhesives for paper products, for example; The probability of cracking during the use of the agent shortens the life of the flocking adhesive after use, and the existing flocking adhesives for paper products generally use relatively highly corrosive initiators, which weakens the flocking adhesive. The safety in the preparation process of the agent is easy to cause splashing when the initiator is added to water for dilution, which improves the operating strength of the operator when preparing the flocking adhesive

Abstract

The invention discloses a flocking adhesive for paper products, and a preparation method thereof. The flocking adhesive is prepared from the following raw materials in parts by mass: 15-25 parts of methyl methacrylate, 35-55 parts of n-butyl acrylate, 5-10 parts of N-hydroxymethyl acrylamide, 3-6 parts of hydrogenated rosin, 2-5 parts of alkylphenol ethoxylates, 4-8 parts of sodium dodecyl sulfonate, 3-6 parts of sodium hydrogen sulfite and an appropriate amount of deionized water. The flocking adhesive and the preparation method thereof have the advantages that oxidation resistance and thermal stability of the flocking adhesive are effectively enhanced through addition of the hydrogenated rosin into the raw materials, so that the probability of cracking during the use of the flocking adhesive is reduced, and the service life of the flocking adhesive after use is prolonged; through the sodium hydrogen sulfite as an initiator, the safety of the flocking adhesive during preparation can be effectively enhanced, so that splashing is avoided when the initiator is diluted in water, and the operation intensitystrength of operators during preparation of the flocking adhesive is lowered.

Description

Technical field [0001] The invention relates to the technical field of flocking adhesives, in particular to a flocking adhesive for paper products and a preparation method thereof. Background technique [0002] Flocking adhesive is widely used in the production and preparation process of daily necessities. With the continuous improvement of living standards, people have higher and higher requirements for daily necessities, prompting the development of flocking adhesives in a new and high-performance direction. As an environmentally friendly packaging material, molded pulp products have the characteristics of a wide range of raw materials, strong plasticity, recyclability and easy degradation, and have been used in many fields. However, the shortcomings of pulp molded products such as rough surface, poor texture, and poor appearance limit their application scope, making it difficult to apply to the packaging of high-end products. In recent years, some people have begun to apply ...
