A kind of preparation method of unsaturated wood substitute

Abstract

The invention discloses a preparation method of an unsaturated wood substitute. The preparation method comprises the following steps: (1) putting substances in a component A into a stirrer according to weight percentage, adding a styrene volatilization inhibitor according to a proportion of 1.7-1.9g / kg, and carrying out sealed stirring and mixing for 15-20 minutes; (2) carrying out vacuum pumping on the uniformly mixed component A; (3) moving the component A from the stirrer to an emptying bucket in batches, adding an accelerant according to a proportion of 0.7-0.9g / kg after carrying out weighing, adding a curing agent according to a proportion of 1.9-2.1g / kg, and carrying out stirring for 10-15 minutes; (4) uniformly stirring the materials in the step (3) and pouring the materials into a mould, moving the mould into a seal box after blowing off the skin blisters of the mould by using an air gun, curing the mould at normal temperature for 1.5-3 hours, and then pumping the styrene gas volatized in the seal box into a sealed cooling tank to collect; (5) drawing the mould to obtain a finished product. The preparation method of the unsaturated wood substitute is environment-friendly in production process, high in raw material utilization rate, low in labor cost, high in production efficiency and stable in quality.

Description

technical field [0001] The invention relates to a preparation method of a wood substitute, in particular to a preparation method of an unsaturated wood substitute. Background technique [0002] "Yogi" is a polymer organic compound, which not only has good strength, plasticity, flexibility, but also has the characteristics of easy cutting, easy carving, no cracking, and no shape change. It is suitable for processing and made into various Various models, such as "sand foundry molds" used as injection molds, will not be reduced in size due to dehydration of traditional wood due to high temperature during mold filling, resulting in reduced accuracy, and can be used as "sand foundry molds" that require high precision for. The main uses of "substitute wood" are: industrial design, shoe molds, standard prototypes, master models, imitation models, jigs for checking, casting molds, stamping molds, vacuum forming molds, injection molds, etc. [0003] With the continuous improvement ...

Problems solved by technology

The production of unsaturated wood substitutes is becoming more and more mature. Styrene, one of the raw materials, has the potential to affect the health of producers and pollute the environment during the production process. Although the amount is relatively small, its negative effects cannot be underestimated. Therefore, how to It is particularly important to reduce styrene emitted into the air during the production process
