Abstract

The utility model provides a kind of high-performance compound painting paperboard, include wood pulp fiber layer and oxytalan layer successively to table from inner, described oxytalan layer using fourdrinier wire starching because forming network structure, wood pulp cellulose therein will be greatly speeded up because being not directly contacted with dissolution velocity after lead plaster, thoroughly solve course of dissolution and apply the problem of paperboard is remained on pole plate, simultaneously as the usage amount of oxytalan is reduced, use cost is substantially reduced.

Description

High-performance is compound to apply paperboard

Technical field

The utility model belongs to pulp technology for making paper, more particularly to a kind of compound painting paperboard of high-performance.

Background technology

Apply paperboard to be mainly used in the paste application process of polar plate of lead acid storage battery, be the paste application process of polar plate of lead acid storage battery In backplate paper.But existing to apply the common paper that paperboard is exactly the string of individual layer, it is poor to there is heat resistance, drying course In easily there is pole plate adhesion phenomenon；Water content is high, reduces pole plate drying efficiency；Impurity ion content is high, accelerates the battery later stage certainly Electric discharge, causes battery capacity to decay；The sour ability of string suction is weak, is unfavorable for the absorption to acid in pole plate formation process, increase The internal resistance of battery；Later stage vitriolization speed is different, and paper is also partly present in polar board surface after chemical conversion, increases internal resistance, makes Into battery capacity and the difference of cryogenic property.

Utility model content

In view of the shortcomings of the prior art, the present invention provides a kind of high-performance compound painting paperboard, and wood pulp cellulose therein is not because Directly dissolution velocity will be greatly speeded up after contact lead plaster, thoroughly be solved course of dissolution and applied the problem of paperboard is remained on pole plate, together The usage amount of Shi Yinwei oxytalans is reduced, and substantially reduces use cost.

To realize goal of the invention, the present invention takes following technical scheme：

High-performance is compound to apply paperboard, includes wood pulp fiber layer and oxytalan layer, described acidproof fibre successively to table from inner Layer is tieed up because forming network structure using fourdrinier wire starching.

Preferably, the wood pulp cellulose of described wood pulp fiber layer is bleached wood pulp, the thickness of wood pulp fiber layer for 11 ± 0.5g/㎡。

Preferably, the oxytalan in described oxytalan layer is modified polyvinyl alcohol fabric, described acidproof fibre The thickness for tieing up layer is 4.5 ± 0.5g/ ㎡.

The compound maximum feature of paperboard that applies of high-performance of the present utility model is that oxytalan is combined with wood pulp cellulose bilayer, acidproof Fiber is combined shaping with wood pulp cellulose in netted, and the product strength is high, gas permeability is high, and oxytalan face is fitted with lead plaster, wood pulp Fiber is not contacted directly with lead plaster, and wood pulp cellulose will be greatly speeded up because being not directly contacted with dissolution velocity after lead plaster, thoroughly be solved molten Solution preocess applies the problem of paperboard is remained on pole plate, simultaneously as the usage amount of oxytalan is reduced, substantially reduces use cost.

Brief description of the drawings

Fig. 1 is the compound structural representation for applying paperboard of high-performance of the present utility model.

Embodiment

The utility model is described in further details below in conjunction with the accompanying drawings.

High-performance as shown in Figure 1 is compound to apply paperboard, includes wood pulp fiber layer 1 and oxytalan layer 2 successively to table from inner, Described oxytalan layer using fourdrinier wire starching because forming network structure；The wood pulp cellulose of described wood pulp fiber layer is bleaching wood Slurry, the thickness of wood pulp fiber layer is 11 ± 0.5g/ ㎡；Oxytalan in described oxytalan layer is fine for modified polyvinylalcohol Dimension, the thickness of described oxytalan layer is 4.5 ± 0.5g/ ㎡.

Embodiment described above is only that preferred embodiment of the present utility model is described, not to this practicality New spirit and scope are defined, on the premise of the utility model design concept is not departed from, ordinary skill in this area The all variations and modifications that technical staff makes to the technical solution of the utility model, all should fall into protection model of the present utility model Enclose, the claimed technology contents of the utility model, all recorded in detail in the claims.

Claims

It is described 1. high-performance is compound to apply paperboard, it is characterised in that include wood pulp fiber layer and oxytalan layer successively to table from inner Oxytalan layer because forming network structure using fourdrinier wire starching, the wood pulp cellulose of described wood pulp fiber layer is bleached wood pulp, The thickness of wood pulp fiber layer is 11 ± 0.5g/ ㎡, and the oxytalan in described oxytalan layer is modified polyvinyl alcohol fabric, The thickness of described oxytalan layer is 4.5 ± 0.5g/ ㎡.
