Abstract

The invention discloses a kind of test methods of plastic storage-battery materials and parts gloss retention, this method comprises: cutting the test plastic sheet and comparison plastic sheet of identical appearance size from same plastic storage-battery materials and parts, test plastic sheet is impregnated into certain time in the aqueous sulfuric acid of certain temperature and concentration, glossiness test finally is carried out with unsoaked comparison plastic sheet, so that it is determined that the stability of plastic storage-battery materials and parts glossiness.The invention is simple and feasible, reliable test result, the test suitable for plastic storage-battery materials and parts gloss retention.

Description

A kind of test method of plastic storage-battery materials and parts gloss retention
Technical field:
The invention belongs to Lead-acid Battery Technology fields, and in particular to a kind of survey of plastic storage-battery materials and parts gloss retention Method for testing.
Background technique:
Lead-acid accumulator plastic part includes the components such as cell jar, exhaust valve, handle.These plastic parts under normal circumstances Basic material be modified polypropylene resin, polyvinyl resin, Corvic or ABS resin.Battery manufacturing process or After a period of use, the glossiness of part cell jar reduces, and has seriously affected the presentation quality of product.In the prior art also Not to the test method of plastic storage-battery materials and parts gloss retention.
Summary of the invention:
The purpose of the present invention is to provide a kind of test method of plastic storage-battery materials and parts gloss retention, this method is simple It is easy, reliable test result, the test suitable for plastic storage-battery materials and parts gloss retention.
A kind of the technical solution adopted by the present invention to achieve the above object are as follows: survey of plastic storage-battery materials and parts gloss retention Method for testing, comprising the following steps:
Step 1: the plastic sheet of identical appearance size, the plastic sheet quantity under cutting are cut from same plastic storage-battery materials and parts For even number, half therein is test plastic sheet, the other half is comparison plastic sheet, and all plastic sheets are placed in drying at room temperature and are protected It deposits；
Step 2: selection glass corresponding with test plastic sheet specification or plastic containers are added in glass or plastic containers Percent concentration is 15%~40% aqueous sulfuric acid, and the liquid level of aqueous sulfuric acid is made to be located at the 1/3 of container height Between~2/3；
Step 3: aqueous sulfuric acid being heated, keeps the temperature at 40 DEG C~60 DEG C；
Step 4: it is immersed plastic sheet is tested in step 1 in the aqueous sulfuric acid of heating, standing 6h~for 24 hours；
Step 5: test plastic sheet is taken out from aqueous sulfuric acid, the aqueous sulfuric acid on surface is rinsed out with tap water, And the droplet of test plastic sheet surface is blotted with muslin or blotting paper；
Step 6: range estimation or the test with the dipped aqueous sulfuric acid of glossiness tester contrast test step 1 under natural light The glossiness of the comparison plastic sheet of plastic sheet and not dipped aqueous sulfuric acid, determines test plastic sheet and comparison plastic sheet glossiness Difference, so that it is determined that the stability of plastic storage-battery materials and parts glossiness.
Beneficial effects of the present invention:
Test method of the present invention is simple and easy, and is corroded at high temperature using strongly acidic aqueous solution, reliable test result, fits Test for plastic storage-battery materials and parts gloss retention.
Specific embodiment:
The present invention is described in further details combined with specific embodiments below.
Plastic storage-battery materials and parts of the present invention include the components such as cell jar, exhaust valve, handle, the test plastic sheet of cutting and The minimum gauge for comparing plastic sheet is 10cm × 10cm.
Black 6-QW-120 type cell jar gloss retention is tested using method of the invention, specific steps It is as follows:
Step 1: the plastic sheet of 6 10cm × 20cm is cut from black 6-QW-120 type cell jar, 3 therein are Plastic sheet is tested, another 3 are comparison plastic sheet, and all plastic sheets are placed in drying at room temperature and are saved；
Step 2: the sulphur that percent concentration is 27% being added in the round plastic container that volume is 9L diameter 25cm or so Aqueous acid, and the liquid level of aqueous sulfuric acid is made to be maintained at 20cm or so；
Step 3: aqueous sulfuric acid being heated with water-bath, keeps the temperature at 55 DEG C ± 2 DEG C；
Step 4: 3 test plastic sheets in step 1 being immersed in the aqueous sulfuric acid of heating, 8h is stood；
Step 5: 3 test plastic sheets being taken out from aqueous sulfuric acid, the sulfuric acid for rinsing out surface with tap water is water-soluble Liquid, and the droplet for testing plastic sheet surface is blotted with muslin；
Step 6: testing the glossiness of 3 test plastic sheets of dipped aqueous sulfuric acid with glossiness tester, be averaged Value is the glossiness of the test plastic sheet of dipped aqueous sulfuric acid；3 comparison plastics of the not dipped aqueous sulfuric acid of test simultaneously The glossiness of piece calculates its average value, and determines the glossiness of the comparison plastic sheet of not dipped aqueous sulfuric acid；If testing plastics More than test value 30 Gloss Unit (Gs) of the test value of the glossiness of piece lower than the glossiness of comparison plastic sheet, illustrate black The glossiness of 6-QW-120 type cell jar is unstable, otherwise illustrates stable glossiness.
