Embodiment 1

[0047] The first step is to prepare compound antifungal agent:

[0048] 1) Pretreatment of cation exchange resin

[0049] Put the 732 type cation exchange resin in the ion exchange column, convert it to H+ type with 5% hydrochloric acid and wash away the excess hydrochloric acid.

[0050] 2) Loading of metal ions on cation exchange resin

[0051] Use 0.25mol / L CuSO4 solution to flow through the + The ion exchange column of the type resin, so that the ion exchange reaction occurs between the resin and the solution, and the resin is converted from H + type conversion to Cu 2+ type, wash off excess Cu 2+ ion.

[0052] 3) Loading of metal ions on the montmorillonite carrier

[0053] The raw material sodium-based montmorillonite and water were made into a soil slurry at a ratio of 1:50, stirred by an electric motor for 24 hours, left to stand overnight, and set aside.

[0054] Take 20L of the upper layer of montmorillonite slurry and add it to a 50L container. Take 2L Cu 2...

Embodiment 2

[0071] The first step is to prepare composite antifungal agent

[0072] 1) Pretreatment of cation exchange resin

[0073] The 732-type cation-exchange resin was packed in an ion-exchange column, converted to H+ type with 6% hydrochloric acid and washed away excess hydrochloric acid.

[0074] 2) Loading of metal ions on cation exchange resin

[0075] Use 0.25mol / L CuSO4 solution to flow through the + The ion exchange column of the type resin, so that the ion exchange reaction occurs between the resin and the solution, and the resin is converted from H + type conversion to Cu 2+ type, wash off excess Cu 2+ ion.

[0076] 3) Loading of metal ions on the montmorillonite carrier

[0077] The raw material sodium-based montmorillonite and water were made into a soil slurry at a ratio of 1:100, stirred by an electric motor for 24 hours, left to stand overnight, and set aside.

[0078] Take 20L of the upper layer of montmorillonite slurry and add it to a 50L container. Take 2L C...

Embodiment 3

[0095] The first step is to prepare composite antifungal agent

[0096] 1) Pretreatment of cation exchange resin

[0097] The 732-type cation-exchange resin was packed in an ion-exchange column, converted to H+ type with 7% hydrochloric acid and washed away excess hydrochloric acid.

[0098] 2) Loading of metal ions on cation exchange resin

[0099] Use 0.25mol / L CuSO4 solution to flow through the + The ion exchange column of the type resin, so that the ion exchange reaction occurs between the resin and the solution, and the resin is converted from H + type conversion to Cu 2+ type, wash off excess Cu 2+ ion.

[0100] 3) Loading of metal ions on the montmorillonite carrier

[0101] The raw material sodium-based montmorillonite and water were prepared into a soil slurry at a ratio of 1:200, stirred by an electric motor for 24 hours, left to stand overnight, and set aside.

[0102] Take 20L of the upper layer of montmorillonite slurry and add it to a 50L container. Take ...

Abstract

The invention discloses a preparation method for mould-proof pigment paste, which comprises the following steps: using Cu<2+> ions as an active component and montmorillonite as a carrier to prepare composite mould-proof agent by an ion exchange method, adding the composite mould-proof agent into leather pigment paste to make the content of the leather pigment paste higher than MIC (minimum inhibitory concentration), so as to obtain a leather product with favorable mould-proof effect. The preparation method puts mould-proof emphasis on a leather finishing process, and makes the pigment paste have mould-proof performance through adding the composite mold-proof agent in the leather finishing process, so as to make finished leather have the mould-proof performance. The leather has the mould characteristic of expanding from the surface of the leather to the inside; therefore, for the finished leather and leather products, the mould-proof finishing treatment in the leather finishing process can effectively prevent the finished leather and the leather products from becoming mouldy during storage, transportation and use.

Description

technical field [0001] The invention relates to a preparation method of an anti-mildew pigment paste, which belongs to the technical field of leather surface treatment. Background technique [0002] As a traditional industry in China, the leather industry occupies a very important position in the national economy. Mildew of leather and its products has seriously affected its use value, resulting in huge economic losses. For a long time, anti-mildew has been one of the problems that the leather industry needs to solve but has not been solved fundamentally. There are many types of molds that can easily cause leather mildew, which vary with the type of leather and the climate and environmental conditions. Among them, the main mold species are Aspergillus niger, Penicillium citrinum, Aspergillus flavus, Trichoderma viride, Penicillium acremus, etc. Aspergillus niger is the most harmful to leather. [0003] At present, there are many types of antifungal agents used in the leat...
