Problems solved by technology

[0002] At present, there are two types of binding adhesives commonly used in the industry: hot-melt adhesive and water-soluble adhesive. Hot-melt adhesive has a firm bond, but the degree of hardening after bonding is high, which makes it difficult to open and read after binding, or the adhesive layer is broken due to a large reading angle. The structure of the spine is damaged. The water-soluble adhesive is relatively soft and can be opened completely, but the bonding strength is not enough, and the pages are easy to drop after repeated reading. Moreover, when the existing adhesive is used for a long time, it is easy to cause the adhesive to mildew due to the influence of the environment. thereby affecting the quality of its use

preparation example Construction

[0025] see Figure 1~2 , in the embodiment of the present invention, calendar adhesive, the preparation method of calendar adhesive is the following steps:

[0026] S1. Put a certain amount of antibacterial and antifungal agent, weather-resistant plasticizing composition, defoamer and emulsifier into the mixing tank, and stir evenly for 15-20min under the condition of 40-50°C to obtain the third component;

[0027] S2. Then put the first component and the second component into the mixing tank, mix evenly with the third component, and stir at a constant speed of 80-90r / min, control the temperature at 20-30°C, and control the stirring time at 20 -30min, after uniform mixing, the calendar adhesive can be prepared;

[0028] Among them, the pH value of the 320-type ternary copolymerization high-viscosity white glue is 6.5-7.5, and the 320-type terpolymerization high-viscosity white glue is passed through the NDJ rotational viscometer with the No. The viscosity measured under temp...

Embodiment 1

[0035] Calendar adhesive, the adhesive is composed of three components, the three components are divided into parts by weight:

[0036] The first component: 40 parts of 320-type ternary copolymer high-viscosity white glue;

[0037] The second component: 30 parts of 7013 latex;

[0038] The third component: 15 parts of antibacterial and antifungal agent, 5 parts of weather-resistant plasticizing composition, 3 parts of defoamer, and 7 parts of emulsifier;

[0039] The antibacterial and antifungal agent is composed of 25 parts by weight of nano-titanium dioxide, 35 parts of nano-zinc oxide and 40 parts of nano-silicon dioxide, and the proportion of nano-titanium dioxide, nano-zinc oxide and nano-silicon dioxide is: 0.25:0.35 :0.4;

[0040] The weather-resistant plasticizing composition is composed of 15 parts by weight of talcum powder, 10 parts of quartz powder, 20 parts of mica powder, 20 parts of amphibole asbestos powder, and the balance is water.

Embodiment 2

[0042] Calendar adhesive, the adhesive is composed of three components, the three components are divided into parts by weight:

Abstract

The present invention relates to the technical field of calendar adhesives, and discloses a calendar adhesive, which comprises, by weight, a first component, a second component, a third component. Thefirst component is 20-40 parts of 320 type ternary polymerization high-viscosity white glue; the second component is 20-30 parts of 7013 type latex; and the third component comprises 10-15 parts of an antibacterial mildew preventive, 5-15 parts of a weather-resistant plasticizing composition, 3-5 parts of a defoaming agent and 7-10 parts of an emulsifier. The adhesive has high bonding strength, the flexibility of an adhesive film is also improved, the adhesive can be conveniently applied to the fields of binding without threads and spine gluing, and the problems of difficulty in reading, book back breakage and page falling can be solved; and meanwhile, the mildew resistance and the elasticity of the adhesive are relatively strong, so that the adhesive is not damaged by thermal expansion and freezing expansion, the weather resistance of the adhesive is improved, and the service life of the adhesive is prolonged.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to calendar adhesives, which are mainly used in the technical field of desk-top calendars and other wireless bindings and spine brushing. Background technique [0002] At present, there are two types of binding adhesives commonly used in the industry: hot-melt adhesive and water-soluble adhesive. Hot-melt adhesive has a firm bond, but the degree of hardening after bonding is high, which makes it difficult to open and read after binding, or the adhesive layer is broken due to a large reading angle. The structure of the spine is damaged. The water-soluble adhesive is relatively soft and can be opened completely, but the bonding strength is not enough, and the pages are easy to drop after repeated reading. Moreover, when the existing adhesive is used for a long time, it is easy to cause the adhesive to mildew due to the influence of the environment. Thereby affecting its quality of u...
