Abstract
The invention discloses a bio-based MS adhesive, which comprises a first component and a second component, wherein the first component comprises the following components in parts by weight: 75-95 parts of silane modified polyether resin, 62-86 parts of common filler, 0.6-1.8 parts of ultraviolet absorbent and 0.5-1.5 parts of silane coupling agent; the second component comprises the following components in parts by weight: 38-72 parts of plasticizer, 10-18 parts of reinforcing filler and 2.3-6.5 parts of catalyst; wherein the weight part ratio of the first component to the second component is 1: 1. The adhesive prepared by the invention has good high temperature resistance, low temperature resistance and weather resistance, and is not easy to crack and debond, thereby overcoming the problems in the prior art.
Description
Technical Field
The invention relates to the field of adhesives, in particular to a bio-based MS adhesive and a preparation method thereof.
Background
Since the advent of MS glue in japan in 1979, more than 40 years of development have been in progress. Referring to data of 2016, in Japan where the MS glue is most developed, the markets of the MS glue and the silicone glue account for 45% and 19% respectively; in addition, the market proportion of MS glue in Europe and America is 30% and 23%. Therefore, the MS glue has a long distance from the sealant crown, namely the MS glue enters China in 2010 and the market of China with the market occupancy of only 2% changes all night. According to the statistics of the Chinese adhesive and adhesive tape industry association, the silane Modified (MS) adhesive in China obtains a high growth rate of nearly 40% in 2020, and keeps the growth rate of more than 20% for three consecutive years, the MS adhesive industry really enters the explosive growth period, and the industry prospect is bright.
The MS adhesive is a cross-linked polymer based on silane terminated polyether, does not contain formaldehyde and isocyanate, has outstanding environmental protection characteristics of no solvent, no toxicity, no odor, low VOC (volatile organic compound) release and the like, has high affinity to qualified human bodies in the environment, is suitable for most building base materials, has good construction property, caking property, durability and weather resistance, particularly has non-pollution property and a coatable property, and is widely applied to building decoration.
However, most of the existing MS adhesives have poor weather resistance and temperature resistance, and when the MS adhesives are applied to outdoor equipment, the MS adhesives are easily cracked and debonded, which greatly shortens the service life of the outdoor equipment.
Disclosure of Invention
Aiming at the problems in the prior art, the invention aims to provide a bio-based MS glue adhesive and a preparation method thereof.
The purpose of the invention is realized by adopting the following technical scheme:
in a first aspect, the invention discloses a bio-based MS adhesive, which comprises a first component and a second component, wherein the first component comprises the following components in parts by weight:
75-95 parts of silane modified polyether resin, 62-86 parts of common filler, 0.6-1.8 parts of ultraviolet absorbent and 0.5-1.5 parts of silane coupling agent;
the second component comprises the following components in parts by weight:

Strontium zirconate titanate behaves more strongly due to the high barium titanate, probably because strontium has a smaller ionic radius, has a greater hydration energy, and is less likely to be adsorbed by clays or colloidal substances, and thus the structural morphology of strontium zirconate titanate behaves more strongly.

In the preparation of the reinforcing filler, the step (2) is to coat the one-dimensional single-wall aluminosilicate nanotube by adopting the strontium zirconate titanate precursor synthesized in the step (1), the selected aluminosilicate nanotube is of a one-dimensional single-wall structure, and compared with the traditional two-dimensional or three-dimensional nanotube structure, the one-dimensional single-wall structure has very high surface activity, can be better combined with the strontium zirconate titanate precursor and has stronger coating performance; in addition, the coating is carried out under hydrothermal conditions, compared with the conventional method for synthesizing strontium zirconate titanate by calcining at the temperature of nearly 1000 ℃, the synthesis method disclosed by the invention has the advantages that the energy consumption is lower, and the coating of the generated product is more uniform.
