Problems solved by technology

[0004] However, in actual use, most DIY markable label paper usually chooses to increase the adhesive effect of the adhesive in order to increase the stickiness of the face paper and prevent the face paper from falling off, but on the contrary, it makes the face paper difficult to tear off after use. If it is opened, it will leave glue marks on the pasted object, which is difficult to remove. At the same time, the surface paper will be damaged, so that the information records on the surface paper will be lost.

Abstract

The invention provides a production process of DIY markable label paper, which relates to the field of label paper production process, and comprises the steps of: Iintroducingpaper sheet raw materialsinto a stirring kettle, heating up to T1, continuously stirring for 40-50 min to a standard gray value while hot air drying, and calendering through a soft roller calendarto obtain a paper sheet; placing adhesive raw material in a reaction kettle, first heating up to T2, stirring and dissolving for 30-40 min, cooling to T3 and continuously stirring for reaction till an adhesive is obtained; coating the paper sheet witha layer of adhesive on the paper sheet by a coating machine with the thickness of the adhesive controlled at 0.8-1.2 mm, and after the coating is completed, adopting the hot airof 135-140 DEG C for drying; after the coated paper sheet is cut, pressing and bonding the paper sheet with a base paper, and perform a secondary cutting to obtain a final product. The invention realizes repeated use of adhesive while effectively increasingimproving the hardness of a paper sheet.

Description

Technical field [0001] The invention relates to the field of label paper production technology, in particular to a DIY markable label paper production technology. Background technique [0002] DIY markable label paper is mostly simple strip paper, generally small in size, which is convenient for timely recording. At present, most DIY labels can be labeled as self-adhesive labels. The self-adhesive label consists of three parts: release paper, face paper and adhesive used to bond the two. Release paper is commonly known as "bottom paper". The surface is oily. The bottom paper can isolate the adhesive, so use It is used as an attachment of the facial paper to ensure that the facial paper can be easily peeled off from the bottom paper, while the facial paper is pressed on the release paper. The user can choose to record various new types on the facial paper, and the back of the facial paper Adhesive is applied. On the one hand, it ensures proper adhesion between the bottom paper a...
