Abstract

The invention relates to a carton composite adhesive. The invention is characterized in that the carton composite adhesive is prepared from the following raw materials in parts by weight: 4-5 parts of urea, 12-15 parts of polyvinyl alcohol, 4-5 parts of melamine, 1-2 parts of tea polyphenol, 4-5 parts of guar gum, 1-2 parts of sodium hexametaphosphate, 6-8 parts of pure acrylic emulsion, 2-3 parts of itaconic acid, 2-3 parts of potassium persulfate, 4-5 parts of natural emulsion, 10-12 parts of styrene-acrylic emulsion, 3-4 parts of crosslinking agent TAIC (triallyl isocyanurate), 1-2 parts of morpholine and 100-120 parts of water. The invention provides a composite simple-component adhesive which can be directly used. The viscosity of the carton composite adhesive is moderate, and thus, the carton composite adhesive can be brushed or sprayed; and the curing speed and initial viscosity are high, and thus, the carton composite adhesive can well satisfy the quick production demands for the carton production line.

Description

A kind of carton composite adhesive and preparation method thereof

Technical field

The present invention relates to a kind of chemical materials, more specifically relate to a kind of tackiness agent.

Background technology

At present, be used for cardboard box glue stick kind a lot, three-aldehyde glue and white glue with vinyl etc. are arranged.Some tackiness agent can discharge free state formaldehyde in production and application process, serious to human body and environmental hazard; Some tackiness agent, water tolerance and wet fastness are poor, easily moisture absorption in damp atmosphere, bonding strength is not high; At high temperature use to produce creep, Joint strength is descended, storing easy freezing below-5 ℃, emulsion is damaged, therefore cause its application greatly limited.The bonding strength that needs research to make new advances is high, the tackiness agent of safety and environmental protection, good stability.

Summary of the invention

The objective of the invention is to overcome the deficiencies in the prior art, a kind of carton composite adhesive and preparation method thereof is provided.

Technical scheme of the present invention is as follows:

A kind of carton composite adhesive is characterized in that being made by the raw material of following weight part: urea 4-5, polyvinyl alcohol 12-15, trimeric cyanamide 4-5, tea-polyphenol 1-2, guar gum 4-5, Sodium hexametaphosphate 99 1-2, pure-acrylic emulsion 6-8, methylene-succinic acid 2-3, Potassium Persulphate 2-3, natural emulsion 4-5, benzene emulsion 10-12, Linking agent TAIC3-4,Morpholine 1-2, water 100-120.

The preparation method of described carton composite adhesive is characterized in that may further comprise the steps:

(1), urea, trimeric cyanamide, tea-polyphenol, guar gum, Sodium hexametaphosphate 99, methylene-succinic acid, morpholine are added to the water, be heated to 60-70 ℃, add again Potassium Persulphate, stirring reaction 1-2 hour;

(2), step (1) material is mixed with other leftover materials, be heated to 50-60 ℃, stirring reaction 1-2 hour, and get final product.

The present invention is the matrix material single-component adhesive, can directly use.Modest viscosity can brush, spray; Curing speed is fast, and initial bonding strength is high, can satisfy well the quick need of production of carton streamline.

Embodiment

A kind of carton composite adhesive, made by the raw material of following weight part (kilogram): urea 4, polyvinyl alcohol 12, trimeric cyanamide 4, tea-polyphenol 2, guar gum 5, Sodium hexametaphosphate 99 2, pure-acrylic emulsion 8, methylene-succinic acid 3, Potassium Persulphate 2, natural emulsion 5, benzene emulsion 12, Linking agent TAIC4,Morpholine 1, water 100.

The preparation method of described carton composite adhesive may further comprise the steps:

(1), urea, trimeric cyanamide, tea-polyphenol, guar gum, Sodium hexametaphosphate 99, methylene-succinic acid, morpholine are added to the water, be heated to 60-70 ℃, add again Potassium Persulphate, stirring reaction 1-2 hour;

(2), step (1) material is mixed with other leftover materials, be heated to 50-60 ℃, stirring reaction 1-2 hour, and get final product.

The tackiness agent of the present invention's preparation, through detecting: after 4 hours, bonding strength reaches 11Mpa, water-tolerant.After bonding, put into 40 ℃ of water and soaked 2 hours, bonding strength is 6 Mpa.
