Problems solved by technology

However, this design is not beautiful enough, bulky, and for the manufacturer, it increases the cost of design and molds, and it is easy to lose waterproofness due to structural damage, such as cracks or missing blocks.
[0003] However, the existing waterproof packaging materials can only be used in construction, home furnishing and other fields, and it is difficult to apply them to electronic products such as mobile phones and PCs. Moreover, the existing packaging materials have certain toxic effects and are not environmentally friendly.

Abstract

The invention discloses a waterproof packaging material for an electronic product based on polypropylene and a preparation method thereof, wherein the waterproof packaging material is prepared from the following compositions in percentage by weight: 4 to 8 percent of polyvinyl chloride, 8 to 12 percent of hydrophilic nanometer silicon dioxide, 5 to 15 percent of polypropylene, 6 to 7 percent of mica titanium pearl powder, 0.5 to 1.2 percent of tantalum carbide, 0.2 to 0.6 percent of styrene-butadiene rubber and the balance of deionized water. The waterproof packaging material provided by the invention is prepared from polyvinyl chloride, hydrophilic nanometer silicon dioxide, polypropylene, mica titanium pearl powder and tantalum carbide according to the specific proportion. A higher waterproof function is realized; in addition, the packaging material is colorless and transparent and has good coating performance; all ingredients are nontoxic ingredients. The preparation process is simple; the operation is simple and convenient; the production cost of the mobile phone production is reduced.

Description

technical field [0001] The invention relates to a polypropylene-based waterproof packaging material for electronic products and a preparation method thereof. Background technique [0002] With the development of society, the advancement of science and technology, and the gradual expansion of the mobile phone market, the performance requirements of consumers for mobile phones are also constantly improving. While mobile phones are becoming more functional and intelligent, they are beginning to pursue humanization, such as waterproofing. Due to the continuous development of functionalization and intelligence on mobile phones, consumers can play with mobile phones anytime and anywhere. They use mobile phones when driving, walking, eating, working, and even when going to the toilet and bathing. However, when taking a shower or going to the toilet, the mobile phone is accidentally dropped into the toilet or sink, so that the mobile phone will enter the water, causing the mobile p...
